Jinling Petrochemical: "Three Pillars" to Control VOCs

Jinling Petrochemical Company conducts targeted treatment of volatile organic compounds (VOCs) emission sources such as volatilization of oil storage tanks, volatilization of oil products loading and unloading, and escaping during sewage treatment, and has formed a relatively complete VOCs treatment pipeline network

Direct Combustion Decomposition Plant West VOCs

"The flame is stable and the combustion is normal

"The direct combustion treatment device is one of the company's measures to upgrade the waste gas treatment method and continuously apply new technologies

At present, the VOCs removal efficiency of the device exceeds 99.

Regenerative Oxidation Plant East VOCs

"This L-shaped device is the RTO regenerative oxidation degassing device

RTO regenerative oxidation is that the organic waste gas is first preheated in the regenerator, and then enters the oxidation chamber, where the temperature is heated to about 900 °C, and the VOCs in the exhaust gas are oxidized and decomposed into carbon dioxide and water

After the RTO device was put into operation, the installation personnel optimized the installation position of the online analyzer for the lower limit of exhaust gas explosion, and adjusted the amount of dilution air and added air filters to ensure the stable operation of the device

　　At present, the tail gas from the intermediate tank area, crude gasoline tank area, benzene tank area, hydrogenation raw material tank area and other areas of the semi-finished product work area of ​​the storage and transportation department in the east area of ​​the company's plant has been pretreated and sent to the RTO unit for advanced treatment.

　　CO catalytic elimination of VOCs in the south of the plant

　　"This is the flow chart of the device

　　The company's waste gas treatment process in the southern area of ​​the plant adopts the technology of "low temperature diesel oil absorption - lye desulfurization and total hydrocarbon concentration homogenization - catalytic oxidation".

　　After the device was completed and put into operation, the company enhanced the catalytic reaction activity, solved the production bottleneck and improved the production efficiency of the device by increasing the inlet temperature of the reaction material by about 90°C, increasing the temperature difference between the inlet and outlet by 30°C, and reducing the flow rate of the mixed gas
