摘　　要：针对液化天然气(LNG)接收站投产初期尚未建立气态外输系统时的蒸发气(BOG)处理问题,基于LNG接收站典型流程提出了新型BOG回收方案。以某大型LNG接收站为例,采用HYSYS软件对新型BOG回收流程进行了模拟计算,明确了新型BOG回收流程应用条件。从技术及经济性两方面验证了新型BOG回收流程是LNG接收站零气态外输工况下BOG处理的有效方式,为LNG接收站的BOG处理提供了新的思路。Based on the typical process flow of a liquefied natural gas(LNG)terminal,a new method for the recovery of boiling off gas(BOG)from the LNG terminal’s non-natural gas(NG)send-out was proposed.Using an LNG terminal as an example,the application conditions of the new BOG recovery process were clarified by simulation calculation with HYSYS and the engineering investment was given.It is technically and economically verified that the new BOG recovery process is an effective way of handling BOG as there is a non-NG send-out,which provides a new solution for the BOG handling of the LNG terminal.
