富乙烷LNG轻烃回收流程中的冷能利用研究

STUDY ON COLD ENERGY UTILIZATION IN LIGHT HYDROCARBON RECOVERY OF LNG

通过建立LNG接收站使用进口LNG,可以有效缓解地区能源供需矛盾,优化一次能源消费结构,推动区域经济可持续发展,改善生态环境。选用适当工艺利用LNG自身冷量回收富乙烷LNG原料中的轻烃,可以降低装置设备的投资和能耗,减少LNG气化过程对周围环境的影响,同时回收LPG也可为LNG接收站带来可观的经济效益。

Importing LNG through the establishment of the LNG terminal can effectively alleviate the contradiction between supply and demand of regional energy,optimize the structure of primary energy consumption,promote sustainable development of regional economic and improve the ecological environment.The appropriate technology of using LNG's cold energy to recover light hydrocarbon in the ethane-rich LNG raw materials can reduce the equipment investment,energy consumption,and the impact on the surrounding environment in the LNG vaporization process.Meanwhile,recovery of LPG will bring considerable economic benefits for the LNG terminal.
