WSH-1催化燃烧催化剂在炼油厂污水场废气治理中的应用

中国石化广州分公司炼油厂污水处理场催化燃烧处理装置采用WSH-1催化剂处理隔油池等废气，在废气量3 000～4 000 m3/h（标准状态）、空速18 000～24 000 h-1、反应器进口非甲烷总烃含量1 350～4 900 μL/L、总硫浓度不大于10 mg/m3、反应器进口温度250～280 ℃的条件下，非甲烷总烃平均去除率为96.9％，苯、甲苯和二甲苯基本被去除，排放气中非甲烷总烃、苯、甲苯和二甲苯等指标符合国家《大气污染物综合排放标准》。两年的运行结果表明，WSH-1催化剂的活性和稳定性与国外进口催化剂相当。

COMMERCIAL APPLICATION OF WSH-1 CATALYTIC COMBUSTION CATALYST FOR TREATING WASTE GASES FROM WASTE WATER TREATMENT SYSTEM IN REFINERY

A catalytic combustion catalyst WSH-1 was developed by Fushun Research Institute of Petroleum and Petrochemical for treating organic waste gases, and it was applied in the catalytic oxidation reactor of waste water treatment system at SINOPEC Guangzhou Company. The more than 2-year running results showed that the activity and stability of WSH-1 catalyst were same as the imported one used with similar conditions. Under a waste gases throughput of 3 000~4 000 m3/h, a space velocity of 18 000～24 000 h-1, a reactor inlet temperature of 250～280 ℃, when the content of non-methane total hydrocarbons at the reactor inlet gas was in the range of 1 350～4 900 μL/L and the total sulfur content of the inlet gas was less than 10 mg/m3, the average removal rate of non-methane total hydrocarbons reached 96.9%, benzene, toluene and xylene were non-detectable. The contents of benzene, toluene, xylene and non-methane total hydrocarbons in the purified gases well met the targets of National Emission Standard.
