摘要针对某一液化天然气 LNG 接收站存在的蒸发气体 BOG 量波动大、BOG 燃烧排放及
单位 BOG 处理量能耗高等问题,分析了 BOG 蒸发量的主要影响因素及维持 BOG 量稳定性的可行
性。提出了对现有操作进行基于储罐操作压力调控的优化方案,优化操作后 BOG 蒸发量稳定性提
高,避免了 BOG 燃烧排放,同时降低了工艺能耗,增加了经济效益。

Abstract In allusion to the problems existing in BOG system of one LNG receiving terminal in China
,
such as great fluctuation of BOG generation high energy consumption of BOG processing and the resource
,
waste of BOG flare emission and so on the parameters that affect BOG generation volume and the feasibility
of maintaining BOG generation stability were analyzed. The existing operation was optimized by using chem-
ical process simulation software. The optimization concentrated on the regulation of pressure of LNG tanks.
,
The stability of BOG generation in optimized operation was improved and BOG flare emission was avoided
which reduced the energy consumption of BOG processing while increased economi
