Industrial Application of Co-treatment of VOCs From Refinery Loading and Sewage Pond
The successful application of the technology of"low-temperature diesel oil absorption-total hydrocarbon concentration homogenization-catalytic oxidation"in an industrial unit for the coordinated treatment of gasoline,the volatile waste gas of aviation coal train loading and the oil and gas escaping from sewage pond was introduced.The loading exhaust gas has the characteristics of high VOCs concentration,complex composition,intermittent discharge,and explosive,and the concentration of pollutants in the waste gas of the sewage tank fluctuates frequently and greatly.The scale of the waste gas treatment device is 600 m3·h-1,and the recovery rate of oil and gas in the exhaust gas can reach over 97%,the total non-methane hydrocarbons in the purified gas was less than 15 mg·m-3,the emission mass concentration of benzene,toluene and xylene was lower than 1 mg·m-3,the ultra-low or near zero emission of VOCs was realized,and the recovery of oil and gas was achieved,having obvious environmental and economic benefits.
