WebbAns: Scrubbers are very efficient air pollution control devices, and can remove greater than 95 percent of the SO 2 from power plant stack emissions. In fact, SO 2 removal efficiencies sometimes are as high as 98 percent to 99 percent. Scrubbers with advanced designs routinely meet targeted efficiencies of more than 95 percent. WebbThey are removed from the FCC offgas by scrubbing in a caustic/water wash tower with caustic solution. If caustic consumption is very large due to a high concentration of CO2, it may be economical to first have an amine wash followed by caustic scrubbing. Acetylene. Acetylene promotes coking in the metathesis reactor.
