Discussion on Standardization of LNG Sampling Technology
The rapid development of large Liquefied Natural Gas(LNG)receiving stations and small and medium-sized LNG plants in China has led to an increasing demand for LNG quality testing and sampling.The representativeness of sampling affects the analysis results of LNG composition,therefore sampling techniques are crucial.In order to develop a national standard for sampling technology that is suitable for various types of LNG stations,through research and analysis of LNG sampling technology and standards at home and abroad,combined with actual application situations and effects,the prob-lems existing in China's current national standard GB/T 20603-2006 are pointed out,and solutions and revision suggestions are proposed.The standard title of Refrigerated Light Hydrocarbon Fluids:Sampling for Liquefied Natural Gas is suggested,intermittent sampling and point sampling method need to be added.It is recommended to use continuous and intermittent methods at LNG receiving stations,con-sistent with ISO 8943:2007,which is beneficial for LNG import settlement in China.It is recommend-ed to use the point sampling method in small LNG plants,LNG refueling stations,and other small sta-tions to meet the sampling needs of small LNG stations.
