LNG轻烃回收流程中换热模拟研究

Study on Heat Transfer Simulation in LNG Light Hydrocarbon Recovery Process

在能源消耗剧增的今天,提高能源利用率有着重要意义。为增加LNG接收站中自带热量的利用,通过对比发现,利用脱乙烷塔外排热量来预热LNG能提高换热效率,能降低20.8%设备能耗,达到节能的目的。

Nowadays, energy consumption has increased dramatically, and it is of great significance to improve energy efficiency. In order to increase the utilization of the internal heat in the LNG receiving station, it was found through comparison that preheating LNG by using the heat discharged from the deethane tower can improve the heat exchange efficiency, reduce the energy consumption of the equipment by20.8%, and achieve the purpose of energy conservation.
