摘要:

为优化LNG 接收站BOG 处理工艺,降低整个接收站的功耗,以外输量为200 t/h、储罐BOG蒸发量为3.04 t/h 的某LNG 接收站为例,对再冷凝工艺和直接压缩工艺两种典型的BOG 处理工艺进行了功耗分析,得出BOG 压缩机和LNG 高压泵的功耗为整个工艺的主要功耗。运用ASPENHYSYS模拟软件对现有工艺流程进行了优化:在现有BOG 处理工艺的基础上,通过对LNG 进一步加压至高于外输压力,靠气化后膨胀高压外输天然气做功来实现BOG 的压缩和对LNG 的加压。优化结果表明:BOG 直接压缩工艺和再冷凝工艺分别节约功耗1 616.27 kW、1 270.64 kW。

Abstract:

To further optimize the BOG treatment process in LNG terminals and reduce energy consumption of the entire LNG terminal, a LNG terminals with LNG output capacity of 200 t/h and BOG evaporation of 3.04 t/h is taken as an example to analyze power consumptions of two classical BOG treatment processes, namely re-condensation process and direct compression process. The results show that BOG compressors and high-pressure LNG pumps contribute dominant proportions in energy consumption. ASPEN-HYSYS simulation software is used to optimize existing processes. Specifically, LNG is further pressurized to a level higher than outlet pressure, and the gasification and expansion of the high-pressure outlet natural gas are used to compress BOG and pressurize LNG. The improved BOG direct compression process and recondensation process can reduce energy consumption by 1 616.27 kW and 1 270.64 kW, respectively.
