Zhongyuan Petrochemical uses cryogenic technology to recover hydrocarbons

A few days ago, Zhongyuan Petrochemical 1500 standard cubic meters / hour non-powered mixed hydrocarbon recovery plant was successfully started, which is the first application
of cryogenic separation technology in domestic polyethylene plants.

The system not only has simple technological flow, convenient operation and control, less floor space, which is conducive to reducing the consumption of the device, but also realizes clean production, has good economic, environmental and social benefits, and is expected to create an effect of about 5 million yuan
for the company every year.

The polyethylene cryogenic separation device transplants the non-powered ammonia recovery technology to the polyethylene tail gas recovery, and the system adopts a multi-channel circulating expansion process, sufficient cooling capacity, and can effectively recover hydrocarbon components without external input power
.
For a long time, there is still a certain amount of mixed hydrocarbons in the exhaust gas of Zhongyuan petrochemical polyethylene plant after membrane recovery, and even if it is recycled to the fuel gas system by the flare system, it still contains high value-added 1-butene, isoamylane, etc
.
