REVIEW OF CANSOLV® SO2 SCRUBBING SYSTEM FIRST COMMERCIAL OPERATIONS AND APPLICATION IN THE OIL AND GAS INDUSTRY
Over the past five years, the CANSOLV® system SO2 scrubbing technology has moved from the status of an emerging technology to that of a commercially realized and technically proven process for economical and highly selective regenerable SO2 capture from gas streams.
Since May 2002, Cansolv Technologies, Inc. (CTI) has successfully realized startup of three commercial applications of their CANSOLV® System SO2 scrubbing technology:
- 10,000 TPY SO2 Unit in Noranda’s smelter operations in Quebec
- 4,000 TPY SO2 Unit for Claus Tail Gas Clean-up at a chemical manufacturing complex in Belgium
- 3,000 TPY SO2 Unit for Spent Acid Recovery Unit Tail Gas Clean-up at ConocoPhillips’ Refinery in Los Angeles
In addition to these commercial operating units, 12 pilot plant campaigns have been executed for a wide diversity of applications including those in boiler and refinery FCC flue gas desulphurization.
In the oil and gas industry, the CANSOLV®, process has particular merit due to the fact that SO2 removal, in some fashion, is routinely required as a part of the basic oil and gas desulphurizing processes and that a convenient use for the recovered SO2 is found in the ubiquitous Claus sulphur recovery unit.
