Main malodor pollutants from oil separator of Refinery A are hydrocarbons and a small quantity of sulfides. Main malodor pollutants from surface aeration tank of Refinery B are sulfides, especially CH3SH. And main malodor pollutants from bubbling aeration tank of Refinery C are also sulfides, of which H2S 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 CH3SH 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%.
