Koch-Glitsch A valves are standard, round full-size valves with a wide operating range and a higher capacity than standard sieve trays.

This is the standard, round, full-size, one-piece valve that has been used successfully in columns around the world for over 50 years.  

• It is provided in several leg lengths to accommodate various tray deck thicknesses 
• It is normally dimpled to help prevent sticking to the deck, but can be flush-seated if needed 
• The orifice can be made to prevent the valve from spinning 
• Dual valve weights may be used in alternating rows to extend the already wide operating range 

BETA RING® random packing from Koch-Glitsch utilizes a unique, proprietary construction to provide excellent surface area for improved separation efficiency.

The BETA RING random packing utilizes a unique, proprietary construction of slots, tabs, and spokes to provide excellent surface area for effective gas and liquid contact and improved separation efficiency. The open structure inhibits fouling by allowing solids to be more easily flushed through the bed by the liquid.

The low aspect ratio of the BETA RING random packing results in preferential orientation when loaded into the tower, which increases capacity and provides lower pressure drop compared to Pall rings and saddles.

CASCADE MINI-RINGS® random packing from Koch-Glitsch is available in multiple sizes to optimize efficiency and capacity for your specific applications.

The low aspect ratio of CASCADE MINI-RINGS random packing results in preferential orientation when loaded into the tower, which can increase capacity and reduce pressure drop. Koch-Glitsch offers multiple sizes of this packing to optimize the efficiency and capacity for your specific applications.

The geometry of the CASCADE MINI-RINGS random packing provides higher efficiency by more efficient use of the packing surface. The open structure inhibits fouling by allowing solids to be more easily flushed through the bed by the liquid.

Koch-Glitsch CASCADE MINI-RINGS® random packing provides more efficient use of packing surfaces with increased capacity and reduced pressure drop.

In 1971, a new approach was taken to the slotted ring packing concept with the introduction of CASCADE MINI RINGS or CMR high-performance random packing. CMR random packing utilizes an aspect ratio of 1:3 (height of the cylinder is 1/3 of the diameter). As a result, the packing elements preferentially orient themselves with the cylindrical axis tending towards vertical. This preferential orientation better exposes both the interior and exterior surfaces of the rings to the liquid and vapor, providing more efficient use of the packing surface. At the same time, this orientation allows a less restricted flow for the vapor, resulting in increased capacity while reducing pressure drop.

Koch-Glitsch continuous vertical support columns provide a simpler tray installation process, reduces installation time and minimizes hot work within a tower.

The Continuous Vertical Support Column provides a simpler tray installation sequence and reduces total installation time. It provides a rigid structure, which minimizes hot work within the tower without any reduction in the tray bubbling area. 

This column is suitable for packed tower revamps involving trays when:

• Changing number of flow passes
• Increasing or decreasing tray spacing
• Changing tray orientation
• Converting packed tower to trays

Expansion rings are used to provide support for the trays where there is no existing welded support ring.  The expansion rings can be leveled even when existing tray support rings are significantly out of level. The continuous vertical columns provide a more leak-resistant connection to the downcomer.

FLEXIFIBER® mist eliminators from Koch-Glitsch provide the highest removal efficiency of sub-micron mists and can help reduce visible stack gas plumes.

Constructed of special media contained between two concentric or flat parallel screens, FLEXIFIBER mist eliminators reduce visible stack gas plumes. For the Koch-Glitsch line of mist elimination products, the FLEXIFIBER mist eliminator provides the highest removal efficiency of sub-micron mists.

Koch-Glitsch offers multiple types of FLEXIFIBER mist eliminators which use the following separation mechanisms:

• Brownian Diffusion (Type BD) 
• Impaction Cylinder (Type IC) 
• Impaction Panel (Type IP) 

Each FLEXIFIBER mist eliminator solution from Koch-Glitsch is engineered and fabricated to the application and specifications: 

• Cages available in multiple metals, plastics, and FRP 
• Packing media produced in glass, plastics, and carbon  
• Skid-mounted units are also available 

FLEXIFIBER® type BD mist eliminators from Koch-Glitsch use Brownian Diffusion to achieve high collection efficiencies for submicron liquid particles.

High collection efficiency on submicron liquid particles; low to moderate pressure drop 

The FLEXIFIBER type BD element uses the Brownian Diffusion mechanism to achieve collection efficiencies of up to 99.95% or higher on all submicron liquid particles down to 0.1 microns. Operating pressure drops are normally designed in the range of 50 to 500 mm (2-20 in) W.G.  

An interesting feature of the FLEXIFIBER Type BD mist eliminator is that, with submicron particles, the collection efficiency actually increases as the gas flow rate decreases through the bed. Increasing residence time in the fiberbed optimizes Brownian movement. 

Type BD elements are cylindrical in shape and are available in a wide variety of materials. The Type BD element with carbon fiber media is recommended if your application contains flourides, a high PH, or is subjected to steam. This will help increase the life expectancy of the element compared to glass fiber media.  

FLEXIFIBER type BD-LdP (low pressure drop) has increased submicron particle collection efficiency with reduced pressure drop compared to conventional fiberbed technology. Because fiberbeds can consume large amounts of energy (such as in chlorine and sulfuric acid production trains), increased efficiency and reduced pressure drop provide significant reductions in operating costs. This technology brings benefits to any process in the forms of decreased investment, lower operating costs, and improved plant performance.  

How it works 
Brownian Diffusion occurs with extremely small droplets that randomly move from side to side, not directly following the path of the gas stream. Typically, the smaller the particle, the greater the Brownian movement. 

Product Benefits

• Reduce or eliminate visible stack gas plumes 
• Provide unlimited turndown from design capacity 
• Achieve guaranteed pressure drop as low as 1.5 in [40 mm] W.G. 
• Interchangeable with existing fiberbed equipment 
• High-efficiency capture of submicron mist particles

FLEXIFIBER® type IC mist eliminators from Koch-Glitsch use impaction to economically and efficiently capture liquid particles in the 1 to 3 microns range.

Economically capture liquid particles in the 1 to 3 microns range 

Primarily utilizing the impaction mechanism, FLEXIFIBER type IC fiberbeds are designed to economically capture liquid droplets in the 1 to 3 microns range. Collection efficiencies at 1 micron will vary from 90% on liquid mists with a specific gravity of 1.0 to 97% on liquid mists with a specific gravity to 1.8. Operating pressure drops are typically in the range of 100-250 mm (4-10 in) W.G.  

In addition to the standard FLEXIFIBER type IC elements, Koch-Glitsch also offers FLEXIFIBER types IC-K, IC-KLF, and IC-M mist eliminators.  

Type IC-K is a low pressure drop, high capacity mist eliminator. It is typically used in applications where frequent washing of the element is necessary, whether it be soluble and insoluble solids. An example of this type of application is sulfate buildup in air drying towers at sulfuric acid plants.  

Type IC-KLF and type ICK combine our knitted wire mesh and fiberbed technologies to produce extended life mist eliminators that are less inclined to foul with solids. This provides energy savings and longer run lengths in critical services, such as sulfuric acid drying towers.  

Type IC-M is an element that uses a primary layer of glass fibers and secondary layer of knitted wire mesh that offers high efficiency and high capacity, i.e. protection against liquid carryover.  

How it works 

Inertial impaction occurs where the mass of the droplet is large enough that it typically cannot follow the path of the gas stream and impacts directly on the target.  

Product Benefits

• High collection efficiency combined with good fouling resistance 

FLEXIFIBER® type IP mist eliminators from Koch-Glitsch use impaction to remove entrainment from vapor and capture liquid particles in the 1 to 3 microns range.

Economically capture liquid particles in the 1 to 3 microns range. 

FLEXIFIBER type IP mist eliminators primarily use the impaction mechanism to remove entrainment from vapor. Collection efficiencies on 98% sulfuric acid mist are essentially 100% on all particles greater than 3 microns, 85 to 97% on all particles 1 to 3 microns and 50 to 85% on 0.5 to 1.0 microns. Operating pressure drops are normally 125 to 180 mm (5 to 7 in) W.G. 

Elements are normally rectangular in shape and are available in various metals, typically metal frames and glass fiber media.  

Type IP fiberbeds are most commonly used in sulfuric acid plants. 

How it works 

Inertial impaction occurs where the mass of the droplet is large enough that it typically cannot follow the path of the gas stream and impacts directly on the target.

FLEXIPAC® CP™ structured packing sets a new standard in post-combustion carbon capture, offering up to 65% reduction in pressure drop compared to traditional structured packings. Its advanced design delivers increased capacity without compromising efficiency, ensuring optimal performance for a wide range of applications.

FLEXIPAC CP structured packing provides a pressure drop reduction of up to 65% compared to existing structured packings used in post-combustion carbon capture service along with an increase in capacity. The low pressure drop and high-capacity of FLEXIPAC® CP™ structured packing:

• Allows for reduced column diameters
• Reduced energy consumption for the blower
• Higher throughput
• Smaller diameter allows for less total solvent required
• Smaller diameter allows for less structured packing volume and brick quantity for shorter installation

While increasing the crimp size of structured packings can offer reduced pressure drop and higher capacity, there is a trade-off of lower efficiency and increased packing height. With FLEXIPAC CP structured packing, this lower pressure drop and capacity is achieved without lower efficiency. The optimization of FLEXIPAC® CP™ structured packing for carbon capture actually improves its efficiency compared to existing X-crimp structured packings in addition to the lower pressure drop and higher capacity. This allows for a packing height reduction or reduced operating expenses due to lower recirculation and regeneration requirements with the same packed height. The improved efficiency of FLEXIPAC CP structured packing:

• Allows for reduced column height
• Reduced overall pressure drop due to less packed height
• Smaller packed height allows for less structured packing volume and brick quantity for shorter installation
• Higher capture efficiency for same packed height
• Reduced solvent recirculation and regeneration for same packed height

FLEXIPAC HC structured packing has been used in thousands of columns to increase capacity and reduce pressure drop for new construction and for replacing standard sheet metal structured packings, conventional random packings, and trays.

FLEXIPAC HC structured packing combines excellent capacity and efficiency characteristics with a lower pressure drop per theoretical stage. It is the preferred packing for vacuum distillation applications.

Similar in construction to FLEXIPAC packing, FLEXIPAC HC packing has a modification in the geometry of the corrugation at the top and bottom for each packing layer. The change in geometry:

• Eliminates the abrupt change in flow direction of the liquid and vapor phases at the packing layer interface
• Eliminates the premature build-up of liquid
• Helps maintain the low pressure drop characteristics of structured packing throughout the efficient operating range of the packing

The advantages of FLEXIPAC HC packing are particularly strong for smaller corrugation crimp size, higher surface area packings.

FLEXIPAC® S structured packing uses a smooth metal packing surface, eliminating the small areas where fouling material can accumulate.

FLEXIPAC S structured packing uses a smooth metal packing surface as opposed to conventional FLEXIPAC packing, which can employ various surface textures. The removal of the surface texturing eliminates the small areas on the packing surface where fouling material can accumulate.

GOODLOE® mesh structured packing from Koch-Glitsch provides high mass transfer efficiency as a knitted wire structured packing solution.

Provides high mass transfer efficiency as a knitted wire structured packing.

GOODLOE mesh structured packing can generate HETP (height equivalent to a theoretical plate) values as low as 2 inches [50 mm] in pilot columns, and values of 3 inches [75 mm] in production columns. These high efficiencies are possible because of the high ratio of surface-area-to-volume inherent in the GOODLOE mesh structured packing design.

GOODLOE mesh structured packing is produced by knitting multiple fine metallic filaments that are then surface textured and either spiral wound or layered into elements for insertion into the tower. The open structure creates multiple twisting paths for the vapor to travel while providing a high-void fraction that minimizes pressure drop. At the same time, the inherent capillary action of the fine wires causes the liquid to spread into thin films that continuously combine and divide for optimum mixing and contact with the vapor throughout the entire packing volume. The peripheral compression feature of the packing construction assures firm contact with the tower wall, minimizing the possibility of vapor bypassing or liquid channeling. The net result is a packing with high mass transfer efficiency and low pressure drop.

GOODLOE mesh structured packing is manufactured in several different styles depending on efficiency and pressure drop requirements.

It is available in 300 and 400 series stainless steel, nickel-based alloys, titanium and many other alloys.

The catalyst for each application is supplied as specified. 

For demanding gas-solid fluidized bed systems, KFBE fluidized bed structured packing from Koch-Glitsch enhances gas-solid contact without restricting flow.

Designed for the demanding needs of gas-solid fluidized bed systems, KFBE structured packing enhances gas-solid contact without restricting flow or allowing solids stagnation. The rugged metal plates turn and break up the catalyst, promoting uniform fluidization and slow, uniform descent of catalyst through the stripper. As steam rises in small turbulent bubbles, hydrocarbon is efficiently stripped. The durable construction of this fluidized bed structured packing is not susceptible to mechanical failure, and the open design resists coking. 

Although FCC catalyst stripping is the largest use of KFBE structured packing, the structured packing is also used in other services that need stripping/replacement of the fluidizing gas in a granular fluidized catalyst.  

KFBE structured packing is supplied in layers that are contoured to fit any vessel configuration or packed column design. Each layer is comprised of packing blocks that fit through vessel manways. Designs account for out-of-round tolerance on vessels as well as for thermal expansion.  

KFBE fluidized bed structured packing has these favorable features, compared to disc-and-donut or baffle/shed trays:

Koch-Glitsch KY-FIBER media is a high-efficiency product specially designed for the separation of fine dispersions of one liquid phase from another.

KY-FIBER media is a high efficiency product specially designed for separation of fine dispersions of one liquid phase from another.  Depending on chemical compatibility and wettability, these elements incorporate glass fiber, carbon or plastic fiber which is positioned between concentric screens in a metal or plastic cage.
 
Similar to the FLEXIFIBER® mist eliminator, these elements are installed via mounting flange onto a tube sheet contained in the separator.  The liquid phases are forced to flow radially through the media, which coalesces the small droplets in the dispersed phase for separation from the continuous liquid phase.

The performance characteristics of KY-FIBER media make it a good fit for dispersions that create a hazy appearance.  Typically, these dispersions are tough to separate with long settling times or conventional media.  KY-FIBER media is not recommended for fouling services.

KY-FLEX® liquid-liquid coalescing media provides superior collection and drainage channels for liquids and solids and comes in a variety of shapes/spacings.

Droplet dispersions require extensive settling when they must travel long distances to the coalescing unit. Liquid-liquid coalescer units uses enhanced gravity settling to allow increased throughput capacity and improve product purity. Enhanced gravity settling minimizes the turbulence effect by dividing the stream into multiple channels. 

KY-FLEX liquid-liquid coalescing units provides superior collection and drainage channels for liquids and solids. A variety of corrugation shapes and spacings are available to optimize the fouling resistance and efficiency to the needs of each process. 

KY-MESH liquid-liquid coalescing media consists of mixtures of metal and non-metallic wires and fibers engineered for the specific chemicals involved.

Applications with smaller droplets that settle very slowly or not at all present a significant challenge. Solutions focus on increasing the size of the droplets so they will quickly separate by gravity settling to minimize vessel length. 

KY-MESH liquid-liquid coalescers consist of mixtures of metal and non-metallic wires and fibers and are engineered for the properties of the specific chemicals involved. The internal geometry promotes growth of the droplet size and maximizes liquid throughput velocities for minimum vessel diameters. 

MINIVALVE® trays produced by Koch-Glitsch produce reduced entrainment and better efficiency than conventional valve and sieve tray designs.

The MINIVALVE® trays produce reduced entrainment and better efficiency than conventional valve tray design and sieve trays. The improvement in capacity can exceed 13% in spray regime services with low-to-moderate weir loadings. MINIVALVE® valves exhibit a more uniform froth action on the tray deck compared to full-size valves. They are offered in both fixed (VG-0) and movable (MV-1) styles. 

MINIVALVE® valves are directional with the rear leg being a little wider than the downstream front leg. This gives a slight pushing action to the liquid as vapor passes through the valves. The liquid push assists in maintaining a more uniform flow pattern on cross-flow trays with less retrograde action. It also helps offset vapor cross-flow channeling effects to a small degree.

High performance packing for thermal mass exchange

BSH packings combine the essential features and properties of sheet metal packings and fabric packings in one packing type. The patented surface structure is an outstanding characteristic of the BSH packing. It consists of rhomboidal openings with alternatively crimped edges. This structure results in an exceptional and uniform wetting of smallest as well as large liquid loads. Turbulences caused by the crimped edges of the openings create a continuous mixing of the liquid film on the packing surface.   

Properties:

• Large capacities and flexibility
• Good wettability and therefore optimum contact areas between gas and liquid
• High separation performance, close to capacity limits
• Liquid loads 0.02 to more than 150 m³/(m² h)

The patented liquid distributor Type S is suited for extremely small sprinkling densities. The special design enables high drip point densities, to achieve a complete wetting of the packing surfaces even at smallest liquid quantities.

The basic design of the MONTZ-Channel Duct Distributor Type S corresponds to the proven MONTZ modular system. Drain pipes are further equipped with draining spouts. This allows the liquid streams flowing through distribution pipes to be further split into several smaller single streams. Even for smaller liquid quantities, drip point densities of >100/m² can be achieved through this design principle                                                                                                                          

Type S:

Plastic Packings made from PTFE for separation of corrosive substances

The MONTZ-Pak Type C1 made from pure PTFE is a structured mass transfer packing with a specific surface of 300 m2/m3. The C1-Packing is manufactured in the shape of round packing elements for smaller diameters and as segments for larger diameters. The packing layers are held together and stabilized in a basket.                                                                           

Properties: The MONTZ-Pak Type C1 structure is very similar to the one of the B1-Packing; this implies that properties such as pressure drop and separation performance are similar. 

Applications:

• Distillation
• Absorption
• Desorption
• Liquid / liquid extraction

Materials:

• Distribution and support systems for the C1-Packing are among other materials manufactured from e.g. Hastelloy C4, B2, Titanium and Tantalum.

Column data:

• Operating temperature up to 130 °C
• Liquid loads app. 2 to 150 m³/(m² h)
• Specific surface of 300 m²/m³
• The smallest possible column diameter is app. 60 mm. The packing elements can be made in one piece up to a diameter of app. 1,500 mm. Manufacturing in segments from 800 mm column diameter is possible.

MONTZ-Pak Type M and Type MN are patented further developments of the proven MONTZ structured packings Type B1 and BSH as well as A3.

Differently adapted and improved wave geometries result in two packing variants which, at identical surface area, increase either the throughout or the separation performance by 30 %. Both packing variations use a patented height-variable wave pattern, which prevents liquid accumulation at the transition zone between two packing layers. The packing types can be characterized as follows: 

The M-Series: Type M packings are particularly suited for throughput increases of up to 30 % for existing columns. It enables a reduced pressure drop at nearly the same separation performance compared to the standard packing. The areas of application include new column as well as existing columns. MONTZ M-Packings offer a 20 - 30 % reduced pressure drop compared to standard packings. Increased throughputs, smaller pressure drops or reduced column diameters are possible due to the streamlined wave patterns. The M-Packing is particularly suited for low vacuum applications and smallest irrigation densities.

The MN-Series: Type MN packings are characterized by an increased separation performance of up to 30 %, at an increased throughput or reduced pressure drop when compared to the standard packing. Higher product qualities and lower overall heights are achievable. 

For new distillation columns, the MONTZ-Packings Type M and MN reduce investment costs with regard to diameter and construction height.

Reductions in column height or / and diameter are possible through the increase in separation performance and throughput. The advantages of both high performance packings are also achieved by retrofits of existing columns. The overall throughput of existing facilities can be increased, product quality be improved or energy reductions can be achieved through the reduction of reflux rates.

Koch-Glitsch MV-1 valves are high-efficiency MINIVALVE® moving valves with higher capacity than full-size valve trays and a wide operating range.

Originally used only on SUPERFRAC® high-performance valve trays, this moving valve is now available for use on conventional trays. This valve offers high capacity, efficiency and a wide operating range. Because of the way the legs are inserted into the deck, the valves cannot spin. The valves come in two leg lengths, although the longer length is rarely needed – the shorter leg accommodates most common deck thicknesses. Valves are normally furnished dimpled with tabs to space the cap edges slightly off the deck. A flush-seated style is available upon request. 

MINIVALVE® valves:

• Provide reduced entrainment and better efficiency than conventional valve and sieve trays
• Provide improvement in capacity that can exceed 13% in spray regime services with low-to-moderate weir loadings
• Exhibit a more uniform froth action on the tray deck compared to full-size valves
• Are directional with the rear leg being a little wider than the downstream front leg
• Provide a slight pushing action to the liquid as vapor passes through the valves
• Maintain a more uniform flow pattern on cross-flow trays with less retrograde action

OMNI-FIT® technology from Koch-Glitsch is a set of mechanical engineering designs used to reduce the cost and downtime of revamps.

OMNI-FIT technology is a set of mechanical engineering designs used to reduce the cost and downtime of packed tower revamps. These technologies include expansion rings, continuous vertical support columns, pedestal supports, downcomer adapters, and innovative mass transfer equipment designs that can minimize or eliminate welding on an existing tower. Efficiency and capacity enhancements can be achieved by using high-performance trays combined with OMNI-FIT technology.

• Can eliminate welding to the vessel shell
• Shorten turnarounds

Koch-Glitsch SUPERFRAC® trays are high-performance crossflow trays ideal for both new construction and revamps that offer high capacity and efficiency.

The patented PLUS technology acts as a deentrainment device and can decrease the efficiency loss that often occurs in low-liquid and high-vapor-rate applications. In these types of conditions, it is common for high vapor rates to blow the liquid off the trays. While the PLUS technology will not prevent a tray from blowing dry, it does help offset the efficiency losses that occur because of high entrainment in low-liquid-rate services. Gains of 5% in usable (efficient) capacity are typical.   

PLUS technology is installed below each tray and helps reduce the entrainment of liquid droplets from one tray to the next. The deentrainment device is a customized design that typically uses a specifically designed FLEXIPAC® structured packing. Because structured packing is used, this technology typically is not applied in fouling services. ​

PROFLUX® severe service grid packing combines the efficiency of structured packing with the robustness and fouling resistance of grid packing.

Engineered to withstand harsh conditions.

The new high-performance severe service grid packing from Koch-Glitsch combines the efficiency of structured packing with the robustness and fouling resistance of grid packing. You get the best of both worlds in a packing that outperforms both of its predecessors in severe services.

PROFLUX severe service grid is a rugged assembly of sturdy corrugated sheets welded to heavy gauge rods. The combination of welded rod assembly and corrugated sheets of increased material thickness provides a very robust design that resists damage from tower upsets or erosion. The gaps between the sheets provide improved fouling resistance by eliminating points of contact between the sheet crimps where solids can collect or liquid can become stagnant and subject to high temperature coking.

Patented Koch-Glitsch PROVALVE® valves eliminate the potential for popped, fouled, or stuck valves, offering low pressure drop and maximum fouling resistance.

The patented PROVALVE® valve offers the wide operating range of conventional valve trays, but with no moving parts. The valve design prevents valve leg or deck wear and eliminates the potential for popped, fouled, or stuck valves.

• The tapered cover imparts a forward lateral push to the liquid across the tray, allows a large open area, and directs and deflects the vapor.
• The result is uniform liquid and vapor distribution across the entire tray with a low, even spray height across the deck. This increases the tray’s efficiency, prevents liquid backflow, suppresses jet flooding, and permits operating at greater vapor rates.
• The cleansing action from the liquid push protects the tray deck from fouling.
• The sheltered valve design allows a large open area that promotes lower pressure drop and protects against vapor surges.

PROVALVE® trays from Koch-Glitsch are designed to eliminate potential for popped, fouled, and stuck valves, with a wide operating range and no moving parts.

The PROVALVE® tray offers the wide operating range of conventional valve trays, but with no moving parts. The valve design prevents valve leg or deck wear and eliminates the potential for popped, fouled, or stuck valves.

The key to the fouling resistance of the PROVALVE® tray is its tapered valve cover, which imparts a forward-lateral push to the liquid flowing across the tray. This directional flow keeps the liquid moving uniformly across the deck, sweeping the deck clean of orifice‐clogging debris.

The directional flow of the PROVALVE® tray also provides uniform liquid and vapor distribution across the entire tray with a low, even spray height across the deck. This increases the trayʹs efficiency, prevents liquid backflow, suppresses jet flooding, and permits operation at greater vapor rates.

With these shop-fabricated beam sections, the installation is safer, easier, and faster. Due to the innovative mechanical design, the Sectionalized Beam provides a greater strength/weight ratio for longer spans compared to traditional beams. The Sectionalized Beam provides openings which allow for communication of process fluids.

SMVP Extraction Packing from Koch-Glitsch is available in various packing types, sizes and materials to meet varying requirements for liquid-liquid extraction.

Liquid-liquid extraction is an important unit operation that is in some instances more economical than ordinary distillation. The separation of constant boiling mixtures (azeotropes) or separation of components with very close boiling points are examples. Another application where liquid-liquid extraction may be employed is the separation of very high molecular weight materials. Even when distilled under vacuum, the high temperatures required may cause product degradation. Counter-current extraction columns equipped with Koch-Glitsch SMV/SMVP Extraction Packings are particularly effective in this regard.

Depending on the extraction application, various packing types, sizes and materials are available which allow for varying requirements of mass transfer efficiency, column capacity and corrosion allowance. Koch-Glitsch can design the extractor internals for either the light or heavy phase being dispersed, depending on the application. The direction of mass transfer, the wetting characteristics of the system, and other operational parameters usually determine which phase will be dispersed and which phase will be continuous.

Operational Features

• No moving parts
• High capacity compared to random packing and trays
• Mass transfer efficiency nearly independent of throughput, within wide operating range
• Suitable for low interfacial surface tension and/or small density differences

Koch-Glitsch also offers metal sieve trays and a full line of random tower packings manufactured from metals, plastics and ceramic materials to suit any extraction requirement.

Super INTALOX® random packing from Koch-Glitsch is favored by designers and industries using ceramic saddles but needing the superior performance of plastic.

Generally, Super INTALOX saddles random packing are favored by designers and industries that once used ceramic saddles but now want the superior performance of plastic Super INTALOX Saddles. Although this packing does not have the "high performance" characteristics of INTALOX SNOWFLAKE®  or BETA RING® random packings, it has been used extensively in corrosive services. Further, it is less sensitive to liquid distribution quality and has higher liquid hold-up and residence time for those services that benefit from such characteristics.

SUPERFLUX® trays from Koch-Glitsch provide increased fouling resistance, which can lead to increased run times between cleaning shutdowns.

To ensure the appropriate technologies are applied for each SUPERFLUX® tray design, Koch-Glitsch engineers work with each client to obtain the specific characteristics of fouling that must be addressed. Features suitable for the specific application are combined into a final design to produce a tray capable of longer run times between cleaning shutdowns.

Conventional Downcomers 
SUPERFLUX® trays with conventional downcomers use active area enhancements and may have inlet area enhancements. The straightforward design of the downcomers allows the use of standard tray construction and simplifies installation.

PURGE Downcomers 
In processes where downcomer fouling is known to cause frequent shutdowns, Koch-Glitsch offers the PURGE downcomer configuration. The PURGE downcomer has proven suitable to resist fouling for such services as polymer slurry, acrylonitrile, and butadiene services.

The PURGE downcomer SUPERFLUX® trays use active area enhancements and may have inlet area enhancements. Very specific advanced downcomer technologies have been applied to the PURGE downcomer trays.

Tray valves 
SUPERFLUX® trays provide increased fouling resistance, which can lead to increased run times. Large diameter fixed valves that are fouling resistant are a standard feature.

Several valve options are available that promote self-cleaning of the active areas. These valves have directional components that utilize vapor energy to provide forward-lateral push on the froth. This action is critically important to maintain proper tray activity and reduce residence time of solids on the tray deck.

Particular attention is paid to the peripheral areas of the deck where stagnation may lead to solids deposition. Directional valves are placed in this area to both increase activity as well as promote a uniform flow profile. These components combine to reduce the residence time distribution and enhance the fouling resistance of the trays.

Such a tray design is suitable for processes which are particularly prone to active area fouling, such as sour water strippers and beer strippers.

They are especially beneficial in applications requiring a large number of mass transfer stages or where mass transfer efficiency is critical to the economics of the operation. Examples include superfractionators (ethylene, propylene), light hydrocarbon fractionators, splitters in chemical and petrochemical applications, and aromatic services.

The patented technologies used in SUPERFRAC trays are the culmination of over twenty years of comprehensive tray development work. The unique combination of SUPERFRAC patented technologies and design strategies produces the high capacity and the maximum vapor/liquid contact efficiency achievable on a cross-flow distillation tray. As a result, the SUPERFRAC tray gives the highest economic benefit to operators of distillation columns seeking solutions for both new construction and revamp projects.

SUPERFRAC trays use active area enhancements and advanced downcomer technologies and may include inlet area enhancements. Koch-Glitsch provides multiple different patented downcomer configurations to optimize the SUPERFRAC tray design for your specific application.

SUPERFRAC® XT trays from Koch-Glitsch are ideal for difficult or high-purity separations and provide maximum tray efficiency/capacity in large-diameter columns.

In larger diameter columns, typical multi-pass designs are limited to four passes. For applications that require more than four passes, the proprietary multi-pass downcomer design can be used to reduce weir loading and improve the capacity of the column.  

Koch-Glitsch has successfully designed large diameter columns that use multi-pass design techniques in 6-pass or 8-pass configurations. The downcomer configuration for a multi-pass design typically is the multi-chordal design; however, almost any other configuration can be used. 

Product Benefits

• Diameters from 13 ft [4000 mm]  
• Difficult or high-purity separations  
• Maximum tray efficiency and capacity 
• Multiple downcomer designs 

Koch-Glitsch T valves are standard, round full-size valves, providing more weepage resistance, corrosion/erosion resistance, and an even wider operating range.

The Type T valve is the caged equivalent to the Type A valve. The use of this FRI-tested valve precedes the Type A valve.

• The Type T valve has a single moving cap with no moving legs protruding through the deck
• A cage assembly retains the cap
• It is more resistant to weeping and to becoming dislodged from the deck
• It is more fouling resistant than the Type A valve
• It normally comes dimpled, but can be flush-seated as necessary

Koch-Glitsch T0 valves are caged, low-pressure-drop valves with a wide operating range and contoured deck holes for the lowest possible pressure drop.

• The dry tray pressure drop is lowered due to the contoured hole in the tray deck providing an overall lower pressure drop
• This comes with a price of higher weepage and reduced turndown

The THORMANN® tray by Montz and Koch-Glitsch is great for low liquid flows, good residence time, and high separation efficiency.

The Thormann tray is designed to handle even the lowest liquid flows, e.g. 40 l/(m²h ) [0.016 gpm/ft²], at a pressure drop as low as 1 mbar per tray.

The arrangement of the caps combined with the special vapor slots ensures a controlled flow pattern of the liquid on the tray and consequently a favorable residence time and a high separation efficiency.

Liquid weeping is minimized (even under minimum vapor flow rates) and can be completely eliminated by seal welding on installation. The vapor risers are formed from the tray deck and prevent the liquid from leaking down by design, which helps to achieve higher separation efficiency.

Optional cooling or heating coils may be provided between the rows of caps for use in, for example, exothermic absorption or reactive distillation applications.

• Maintain a more uniform flow pattern on cross-flow trays with less retrograde action

Koch-Glitsch VG-10 valves are full-size fixed valves with large opening for improved fouling resistance and rugged construction for longer tray life.

This is a full-size fixed valve that is anything but conventional.

• The net rise typically ranges from 0.236 in [6 mm] to 0.551 in [14 mm], varying in 0.039 in [1 mm] increments (other lifts may be available in some cases)
• This valve is also directional with the rear leg being visibly wider than the downstream front leg
• As with any fixed valve, it can never become stuck to the deck, nor can it spin
• The large net rises available plus the directional liquid flow make this an outstanding anti-fouling valve that is widely used on anti-fouling SUPERFLUX® trays
  • Using a large net rise ensures that large particles can freely pass through the deck openings
  • There are no protrusions below the deck for any material to hang up on and for deposits
  • The liquid push is strong enough to help solid material be flushed downstream and toward the downcomer where it can exit off the tray deck

VORSOMAX® cyclone mist eliminators from Koch-Glitsch help reduce vessel size or increase capacity in high-pressure applications with high gas handling capacity.

Reduce new vessel size or increase capacity in high pressure applications. 

VORSOMAX  cyclone mist eliminators consist of single or multiple elements mounted onto a deck plate. Each element contains an activator which generates centrifugal forces to provide the separation of vapor and liquid(s).  The units are provided in easily handled subassemblies, which are installed through vessel manways.  If the vessel is equipped with a body flange, the elements may be consolidated into a single piece for installation via the body flange. 

• VORSOMAX  cyclone mist eliminators deliver very high gas handling capacity combined with excellent droplet removal efficiency even at elevated pressures. 
• For grassroots projects involving high pressure separators, cyclone mist eliminators can provide the lowest overall cost solution by minimizing the diameter and height requirements of the vessel. This reduction in footprint can result in several benefits to the end user such as: faster vessel delivery, lower transportation costs, simplified installation and lower overall vessel costs.
• For existing high-pressure separators, where significant additional capacity is required, cyclone mist eliminators can extend the gas capacity well beyond any other mist elimination technology.
• Cyclone mist eliminators are used in the advanced two-stage DEMISTER-PLUS® mist eliminator to provide high throughput capacity.  

Product Benefits

• Minimizes grassroots vessel diameter and weight, which is particularly important in high pressure applications
• Ideal for debottlenecking existing separators for capacity upgrades
• High gas turndown
• Easily installed through vessel manways 

VORSOMAX® cyclonic inlet devices deliver good separation of vapor and liquid phases and decrease the momentum of feed streams entering inlet nozzles.

The VORSOMAX cyclonic inlet device is a patent-pending inlet device that delivers good separation of vapor and liquid phases. It consists of a manifold and a series of separation cans, in which centrifugal force is generated to provide the vapor-liquid separation.

• Ideal for debottlenecking existing separators for capacity upgrades

Koch-Glitsch wire gauze packing is the preferred packing in distillation service for deep vacuum and low-liquid-rate applications, delivering excellent efficiency.

Koch-Glitsch wire gauze packing is the preferred packing in distillation service for deep vacuum and low-liquid-rate applications. The characteristic of lowest pressure drop per theoretical stage makes wire gauze packing the preferred device for processing specialty chemicals, pharmaceuticals and temperature-sensitive materials.

Wire gauze packing is generally used in small- to medium-diameter columns to achieve the maximum number of theoretical stages in the minimum column height. Because of the capillary effect, the wire gauze material provides an extremely wettable surface for low-surface-tension liquids, resulting in excellent mass transfer efficiency, particularly at very low liquid rates
