Reducing the emissions of volatile organic compounds(VOCs)is an important issue in the field of environmental governance in China during the 14th Five-Year Plan period.The existing VOCs treatment technologies can be divided into three categories,namely condensation recovery,adsorption absorption,and decomposition,among them,adsorption absorption technology has high treatment efficiency and good economy,making it a relatively ideal VOCs treatment method.However,the existing VOCs adsorption absorption technologies have poor universality.The experiment uses a combination of polyol polyether and fatty alcohol as absorbers,after testing,the combination of"trimeric glycerol/tetraethylene glycol+triethylene glycol monoether/tetraethylene glycol dibutyl ether+dodecanol"has an absorption rate of over 98%for four simulated VOCs,namely n-hexane,dichloromethane,toluene,and acetone,in the working condition testing of the chemical pilot plant,the combination of"trimeric glycerol+tetraethylene glycol dibutyl ether+dodecanol"achieves over 99%VOCs absorption,and the concentration of VOCs in the treated exhaust gas does not exceed 10 mg/m3.
