我国中纬度地区的液化石油气储配站(以下简称充装站)的管道大多数是受阳光直接照射的,对于那些管线设计长度过长的充装站,高温季节在液化气液相管道远端容易出现“气塞”现象。如何避免或减轻“气塞”的影响,以降低充装损耗,消除充装站的隐患,是充装站管道设计中应注意的一个问题。 China’s mid-latitude liquefied petroleum gas storage and distribution stations (hereinafter referred to as the filling station) most of the pipes are exposed to direct sunlight, for those long pipeline filling station design, high temperature season in liquefied gas liquid pipeline End prone to “air plug ” phenomenon. How to avoid or reduce the influence of “air plug” to reduce the filling loss and eliminate the hidden trouble of the filling station is a problem that should be noticed in the design of filling station pipeline.
