LNG调峰站BOG直输城市中压管网工艺研究

Analysis of BOG Directly Entering Urban MP Network from LNG Peak-shaving Station

通过对蒸发气(BOG)产生原因的分析,给出了站内各工艺区BOG蒸发量的计算方式,并结合BOG常用的处理工艺,对BOG直接压缩输入城市中压管网的可行工况进行了探讨。采用适当的方式处理好BOG,不仅能保障LNG站运营的安全,也能实现能源的充分利用。

Based on the analysis of the causes of BOG, the calculation methods of evaporation in each process area of the station are given. Combining with the common treatment processes of BOG, the feasible operating conditions of BOG directly compressed into urban medium pressure network are discussed. The proper way to deal with BOG is not only to ensure the safety of LNG station operation, but also to make full use of energy.
