Zhongyuan Petrochemical uses cryogenic technology to recover hydrocarbons
China Drying News Co., Ltd. Recently, Zhongyuan Petrochemical's 1500 standard cubic meters/hour unpowered hybrid hydrocarbon recovery unit was successfully launched. This is the first application of cryogenic separation technology in domestic polyethylene equipment.
According to reports, the system not only has simple process flow, convenient operation and control, and has a small footprint, it is conducive to the reduction of equipment consumption, and it also achieves clean production. It has good economic, environmental and social benefits and is expected to be created annually for the company. The effect is about 5 million yuan.
Polyethylene Cryogenic Separation Device is to transplant non-power recovery ammonia technology into polyethylene tail gas recovery. The system adopts multi-channel cyclic expansion process with sufficient cooling capacity. It can effectively recover hydrocarbon components without external input power. For a long time, after the membrane recovery of Zhongyuan Petrochemical's polyethylene plant, there is still a certain amount of mixed hydrocarbons in the exhaust gas. Even if the fuel gas system is recovered through the flare system, it still contains high value-added 1-butene, isopentane and so on.
