轻质组分LNG对LNG接收站卸船操作的影响分析

Inf luence Analysis of Light Component On The Unloading Operation of Lng Terminal

随着澳大利亚柯蒂斯项目建成投产,预计气电集团未来半数以上LNG供应将采用柯蒂斯项目气源(简称柯气)。由于柯气组成较轻,被称为轻质组分LNG,其气化热小,在接卸、储存、运输过程中将会出现较LNG平均组份或重组份BOG产生量增多的情况[1]。结合珠海LNG、浙江LNG和大鹏LNG接卸轻组分LNG的实际情况,分析轻质组分LNG对接收站卸船操作的影响,并提出相应的建议方案。

As the Curtis project in Australia was built-up and put into operation,for the LNG terminal of Gas&Power Group,half of the LNG supply will be from the Curtis project(refered to as curtis gas).Due its component is too light,it is called light-component LNG and its evaporating heat is less than normal LNG.More BOG will be generated than normal-component or heavycomponent LNG.Based on the unloading practice of ZhuHai LNG、ZheJiang LNG and DaPeng LNG,analysising the influence of light-component LNG on the unloading operation and giving corresponding suggestion.
