With the rapid development of science and technology, the consumption of fossil energy rises sharply, and the problem of waste gas pollution in the petrochemical industry has become increasingly prominent. It is imperative to improve the energy conservation and emission reduction work. VOCs unorganized emission from the tanks and the liquid loading and unloading links in an oil storage area caused the oil volatilization loss of 916.53 t/a, which seriously affected economic benefits and generated potential risks of diffusion of toxic gases such as benzene. Because the treatment effect of activated carbon adsorption and recovery process commonly used in China on aromatic hydrocarbons did not meet national new emission standards(≤20 mg/m~3), the complex technology of adsorption and condensation to recovery volatilized oil was used to increase the volatile oil recovery and to guarantee the concentration of poisonous gas in tail emission to meet the standards.
