Abstract: This paper introduces the treatment scheme of volatile organic compounds (VOCs) on the top of 10 tanks in the refinery intermediate oil products farm of a petrochemical plant. The revamp scheme utilizes the existing gas pipeline network system of the refinery to recover and reuse the VOCs. It also includes oil and gas collection pipelines and booster fan on the tank top, and improves nitrogen seal and safety accessories of storage tanks. The revamp scheme needs to formulate reasonable pressure control plan and emergency safety measures according to the basic situations of the storage tanks. The treatment scheme has the advantages of small investment and low operation cost. It not only cancels the exhaust gas outlet, but also has higher economic benefits. It can be used as the preferred treatment scheme for refinery top tank air.
