COPE ™ Process: ConocoPhillips Lake Charles Refinery - Introduction to Industry and Continued Development.

摘要

The COPE ™ Process was first developed and commercially introduced at the ConocoPhillips Lake Charles Refinery in 1985 to permit increasing the capacity of Claus Sulfur Recovery Units (SRUs) by utilizing oxygen instead of air in the main reaction furnace burner. There are 32 COPE trains with over 350 train years of operating success. Historically, the COPE Phase II Process has successfully demonstrated the use of a blower to sustain recycle stream flow. The newest innovation uses the patented COPE Ejector Process, introduced in 1998, for recycling the process gas. The first unit was commissioned and has operated successfully since July 2000. The COPE Ejector Process has proven to provide significant mechanical advantages and beneficial results on critical aspects of the overall process chemistry. These advantages have translated into high capacity and process reliability in a robust process with both capital expenditure and operating cost advantages. There is now in excess of twenty five years of high level oxygen-enriched COPE process operating experience at the ConocoPhillips Lake Charles Refinery and ten plus years utilizing the COPE Ejector Process. This paper will provide the fundamentals of oxygen enrichment, the development of the COPE Process and actual construction, operating and maintenance data from the Lake Charles Refinery
