| FCC gas plant stripper capacity |
Dave Langdon, Total Lindsey Oil Refinery (LOR) Ltd
Tony Barletta and Scott Fulton, Process Consulting Services Inc |
2004 / Revamps |
Deethaniser operating difficulties can be caused by water phase formation, water entrapment, foaming and other factors. "Short-term" capacity improvements implemented at one refinery were able to eliminate these difficulties.

| Process Equipment specification and selection |
Christopher F Dean, Saudi Aramco
Scott W Golden and Richard E Pulley, Process Consulting Services |
2004 / Revamps |
Process design as well as equipment specifications and selection can cause unintended problems following unit revamps. Identification of the true constraints may result in significant capital savings.

| Conditions influencing coke formation |
Tony Barletta, Process Consulting Services Inc
|
2004 / Revamps |
Hotspots in fired heaters can lead to accelerated rates of coking and tube failure. Two examples show how integrating fireside and oil-side calculations can help identify and correct conditions leading to high localised peak flux rates.

| Steam reboiler system operations |
Ken Weston, CITGO Petroleum Corporation
Steve White, Process Consulting Services Inc |
2004 / Revamps |
Basic heat exchange principles are used to explain gas plant thermosiphon reboiler hydraulic constraints. Field measurements help clarify "off-design" operations that were not apparent and were causing high condensate levels.

| Producing sulphur-free diesel |
Gordon Low Haldor Topsoe Inc
Jamie Townsend and Tim Shooter BP |
2004 / Revamps |
A systematic approach to revamping a low-pressure HDT. 10 ppm diesel production at the BP Coryton refinery was possible without the expense of building a new high-pressure unit.

| Vacuum ejector performance break |
Norm Lieberman, Process Improvement Engineering
Edward Hartman and Daryl Hanson, Process Consulting Services Inc |
2004 / Revamps |
Understanding vacuum ejector performance is the key to maintaining reliability and distillate yields. A low VGO yield may result from a breaking ejector system, but bypassing a fouled inter-condenser can restore lost yield.

| Targeting overhead exchanger failures |
Richard Mathers, Nalco Energy Services LP |
2004 / Revamps |
A complete risk assessment of severe crude unit overhead corrosion reduced corrosion-related failures. Costly equipment upgrades were avoided and significant savings generated without any increase in operating expenditure.
