Wang Liangjun1,Liu Yang1,Luo Zaiyuan2,Liu Shan2,Zhao Chunyu3(1.Daqing Petroleum Institute,Daqing,Heilongjiang 163318,China;2.Guangdong Dapeng LNG Company Ltd.,Shenzhen 518048,China;3.CNOOC Shenzhen Natural Gas Co.,Ltd.,Shenzhen 518040,China)  
The large-scale atmospheric LNG storage tank is an important facility at LNG receiving stations and it involves high investments.It requires high commissioning techniques when it comes on stream.The most crucial and dangerous step in the commissioning of LNG storage tank is cooling.This paper hereby introduces the cooling process of the common 160,000 m3-in-capacity atmospheric LNG storage tank in China,the preconditions and matters to which attention is paid upon the cooling of tank.It also discusses some commissioning techniques needed in the cooling process,including pressure control,cooling medium (LNG) supply and its flow control,process monitoring and cooling rate control,etc.The paper points out that the displacement of pipelines is easily to be overlarge and flange leakage takes place frequently in the cooling process and it gives corresponding solutions.So it provides good references for other LNG projects.
