Yangzi Petrochemical innovated ethylene recovery technology

a few days ago, the new membrane separation ethylene recovery unit of Yangzi petrochemical ethylene glycol unit will also lead to the successful operation of fixtures or sensors, which not only effectively recovers part of the discharged ethylene, but also protects the quality of the atmospheric environment. The annual recovery of ethylene is 800 tons, with an efficiency increase of more than 6 million yuan

in the production process of ethylene glycol combined unit, part of the ethylene content will be discharged in the circulating gas, and its ethylene concentration is about 27%. In order to further reduce material consumption, recover ethylene, make better use of resources, and improve the operation economy of the unit, Yangzi Petrochemical Company, drawing on the technology of ethylene glycol units at home and abroad, cooperates with well-known domestic companies to implement the technical transformation of the project of "please consult for specific details of membrane separation application. From a domestic perspective, recover ethylene from the exhaust gas of ethylene glycol units" by using the characteristics of preferential permeability of special polymer membranes to ethylene, The ethylene in the mixture can be enriched and recovered through the membrane, and has the characteristics of safe operation, environmental protection and energy saving. The ethylene recovery rate is more than 80%
