DEEP PURIFICATION TECHNOLOGIES FOR VOCs WASTE GASES DURING LOADING OF GASOLINE, JET FUEL, STYRENE AND METHANOL

Abstract

Abstract: The emission standards for volatile organic compounds（VOCs）waste gases such as gasoline, jet fuel, styrene, etc, and the collection and transportation technologies for oil product vapors were summarized, showing that domestic standards are comparable to or even slightly stricter than the foreign strictest standards. It is recommended to transport the VOCs out of top immersed crane pipe to the processing equipment by fans. A series of loading VOCs deep purification technologies developed by SINOPEC Dalian Research Institute of Petroleum and Petrochemicals （former Fushun Research Institute of Petroleum and Petrochemicals, FRIPP）were introduced, including "Low-Temperature Diesel Absorption" ，and "Low-Temperature Diesel Absorption-Total Hydrocarbon Homogenization - Catalytic Oxidation (AHCO-1) " technology, and "Low-Temperature Diesel Absorption - Incineration" technology for gasoline, jet fuel, styrene. The "Water Absorption - Total Hydrocarbon Homogenization-Catalytic Oxidation (AHCO-2)” technology for methanol, and acetic acid, the condensation generative thermal oxidation" technology for gasoline oil and gas treatment. After treated by "Low-Temperature Diesel Absorption" technology, the recovery of gasoline oil and gas can reach over 97%; similarly, for the loading VOCs, the total hydrocarbon concentration of purified gas is less than 20 mg/m3, while the total hydrocarbon removal rate is more than 99% by recycling, catalytic oxidation, incineration treatment.

Key words: gasoline , jet fuel, styrene, methanol, loading, VOCs, low temperature diesel absorption, catalytic oxidation
