液化天然气加气站低温潜液泵进口管路布置讨论

Layout Discussion on Inlet Pipe of Cryogenic Submersible Pumping for Liquefied Natural Gas Filling Stations

针对液化天然气加气站因储气罐与低温潜液泵相对位置不当引起液化天然气输送不畅的问题,通过分析管道倾斜程度对输送液化天然气气液两相流的影响,提出了正确设计两者相对位置的垂直-水平设置管路的方法。

A design method is induced to solve the problem that the liquefied natural gas （LNG） filling station operates improperly caused by the improper relative position between the liquefied natural gas storage tank and the cryogenic submersible pump.The influence of the placement of a pipe on the two-phase flow is analyzed.The conclusion that vertical placement of a pipe is the most suitable in this situation is made.
