How high performance trays can deliver the best capacity and efficiency.
A process review, including the improvement of atmospheric and vacuum distillation columns, for the reformulation of the diesel pool.
To save project costs, the distillation towers for a new refinery were designed to meet process design objectives using best available technology.
Component trapping by physical carry-over of water can cause capacity bottlenecks that are not easily predicted.
Exploring the factors that influence vapor crossflow channeling.
Revamping a heavy oil upgrader's steam stripping tower increased tray efficiency and achieved record throughput.
Low-cost revamps of tower internals improve production from existing assets with a payback period of less than a year.
A description of the installation of 6-pass trays in a large C3 splitter.
As a first step in an ethane extraction plant's operational improvement plan, a tray revamp was performed to improve both tray efficiency and ethane recovery.
Retrofitting the packed top section of a crude atmospheric tower with high capacity trays improved separation efficiency.
Addressing the challenges involved with large diameter trayed towers.
Case studies to question whether there needs to be a trade-off between capacity and efficiency in large diameter trayed towers.
CPI companies are switching to fixed valves despite a slight loss in operational flexibility. Fixed valves offer better reliability, fouling resistance, and more robust valve designs.
Explore the process of troubleshooting, reviewing operating data and scans, and evaluating the economics of revamping a tower in 1995 and again in 1999.
When simulating or designing an unconventional heavy oil/bitumen vacuum crude unit, the sharing of operating data on cracked gas make, stripping section performance and indirect entrainment can help ensure designers make the right design choices.
