摘要： A green treatment process for cleaning exhaust gas generated in the air oxidation of benzene homologs is disclosed. It takes the hot pressurized exhaust gas generated in the benzene homolog air oxidation process as driving power and heating source: firstly, introducing the said exhaust gas into a turbine refrigerator so that it can drive the refrigerator to generate the cooling capacity that will be utilized for condensing the gas phase in the upper part of the flash evaporator and for trapping organics entrained in the exhaust gas; then, leading the exhaust gas with lowered temperature and pressure into corresponding heat exchangers to provide a part of heating source for the flash evaporator and to preheat the reaction raw materials. Furthermore, introducing the condensed exhaust gas into a water absorption scrubber for further removal of trace organics entrained therein.
