Abstract: Benzene, toluene and xylene are toxic substances. According to the deployment of Sinopec, the VOCs of benzene storage tanks should be treated. This paper proposes the transformation plan for benzene storage tanks and the selection of process routes for oil vapor recovery device. After the project is put into use, the oil vapor in the storage tank is fully sealed for recovery and the oil vapor recovery device is in unattended operation, and the exhaust gas reaches the standard discharge. This reduces the evaporation loss of the medium, enhances the intrinsic safety of the tank area and improves the air quality of the tank area. It is conducive to the health of employees.

Key words: evaporation loss, oil and gas recovery, energy conservation, safety, environmental protection
