中小型液化天然气装置流程及布置

The Process and Layout of Small and Medium Sized LNG Plant

以西北某城市液化天然气工程为例,介绍了中小型液化天然气装置预处理和液化的工艺流程,以及液化天然气大储罐布置的注意事项。根据实际的气源条件,考虑到减少投资、增大效率的前提,推荐采用分子筛脱水+单循环混合冷剂制冷工艺。

To LNG （liquefied natural gas） project in the northwest city as an example, introduced the small and medium sized LNG plant pretreatment and liquefaction process, as well as LNG storage tank layout. According to conditions of gas source, taking into account less investment and higher efficiency of the premise, the recommended process is molecular sieve dehydration and simple closed loop mixed refrigerant refrigeration cycle.
