摘　　要：首先简要介绍了目前LNG储运装置BOG产生的现状,以及目前回收BOG再液化的一些方法。接着分别针对低温制冷机和液氮作为冷源的两种回收再液化方法从设备投资(两者相当)、运营成本(前者比后者低约40%)、投资回收周期(两者相当)等方面进行综合分析比较,最终得出用低温制冷机作为冷源再液化BOG成为LNG是经济的(液化1kg的BOG仅需花费1.35元)。This paper briefly introduced the present situation of BOG from LNG storage and transportation device, some re- cycling and re - liquefied methods of BOG. Based a cryocooler and liquid nitrogen as cool source, two re - liquefied methods were compared from the equipment investment cost , operation cost （ the former method is about 40% lower than the latter method） and the investment recovery period （both are similar）. Finally a conclusion was found that eryocooler was more economy （ Cost for liquefying BOG of lkg is only about 1.35 yuan）
