Special-fabric packing for separation of thermally unstable substances under vacuum
MONTZ-Pak Type A3 satisfies particularly the special demands posed by the separation of thermally unstable substances under vacuum conditions. This becomes possible primarily through a special fabric with excellent wetting characteristics by capillary effect, which form the packing layers in the shape of rippled disks. This packing type also works very well for very small quantities of liquid loads due to low pressure losses and high separation efficiencies.
Properties:
- Particularly suitable for vacuum columns
- Very small liquid loads (< 100 l/m²h) are possible
- Lowest pressure drop per theoretical separation step
- High separation performance through good wettability of packing surface
- Capillary effect of special fabric
Application:
- Areas of application are mainly in the separation of thermally unstable substances, which can be fractionated in vacuum of e.g. 0.5 mbar.
- Distilled oils
- Isomer mixes
- Fatty acids
- Fatty alcohols
- Deodorizing of salad oils
- De-gassing of transformer oil
- Pilot columns
- Vitamins
Column data:
- Diameter from app. 20 mm up to 7 m and wider
- Very low liquid loads (e.g. 20 l/m²h)
- Very low operating pressures (e.g. 0.5 mbar)
- Minimum liquid hold-up
