摘要
上海某石化企业储罐及污水池排气采用低温柴油吸收-碱液脱硫-总烃均化-蓄热氧化工艺处理。在吸收油量20 m^3/h、吸收温度5～12℃、吸收压力0. 18 MPa、蓄热氧化反应温度670～820℃及氧化停留时间2～5 s条件下,净化气中非甲烷总烃排放浓度小于10 mg/m^3,苯、甲苯、二甲苯浓度小于低检出限,且净化气中SO2和NOx浓度均小于25 mg/m^3,满足国家及地方标准排放要求,具有明显的环保及社会效益。废气处理装置的实际运行能耗折算值约为22. 2 kg(标准油)/h,年运行费用约为138. 5万元。
In a petrochemical company in Shanghai,the discharge gas from storage tank and waste waterpit is treated with the process of low-temperature diesel absorption-sulfur removal by caustic liquid-total hydro-carbons equalization-thermal storage oxidization. Under the conditions of 20 m3/hr flowrate of absorption oil,5 ~ 12 ℃ absorption temperature,0. 18 MPa absorption pressure,670 ~ 820 ℃ thermal storage oxidation reac-tion temperature and 2 ~ 5 seconds of oxidation residence time,the total non-methane hydrocarbon dischargeconcentration in the discharge gas is lower than 10 mg/m3,and the concentrations of benzene,toluene and xy-lene are lower than minimum detection limits. The SO2 and NOxin purified gas is lower mg/m3,which meetthe emission specifications national and local standards. Both environmental protection and social benefits areobvious. The actual energy consumption in the operation of waste gas treatment unit is about 22. 2 kg( stand-ard oil)/hr,and the annual operation cost is about 1,385,000 Yuan( RMB).
