AM-96-47 INNOVATIONS IN FCCU WET GAS SCRUBBING

Description:

Within a modem petroleum refining complex, one of the most important and profitable processes is the Fluid Catalytic Cracking Unit (FCCU). As early as 1974, New Source Performance Standards (NSPS) were promulgated regulating the amount of particulate and carbon monoxide which could be emitted from an FCCU. On August 17, 1989, the US EPA (Environmental Protection Agency) promulgated additional regulations which regulate sulfur oxide emissions from FCCU’s. In setting a NSPS, EPA is required to set the standards based on “Best Demonstrated Technology ” or BDT. For the current regulation, EPA has determined that scrubbers are BDT.
