Main malodor pollutants from surface aeration tank of Refinery B are sulfides, especially CH 3SH. And main malodor pollutants from bubbling aeration tank of Refinery C are also sulfides, of which H 2S concentration is the highest. Catalytic combustion technology is applied to treat malodorous gas from oil separator of Refinery A, in which the total hydrocarbon removal was over 97%. The purified gas meets the national standard. Activated carbon adsorption is used to treat malodorous gas from surface aeration tank of Refinery B, and main pollutant CH 3SH removal reached up to 98%~100%. As for malodorous gas from bubbling aeration tank of Refinery C, bio packing tower is used and the removals of hydrogen sulfide, organic sulfides and benzene series reached up to 80%~98%.展开更多
