LNG接收终端工艺对比及选择

Process Selection of LNG Receiving Terminal

LNG接收终端工艺流程和气化工艺的对比及选择问题是LNG接收终端高效、经济运行的关键。本文对气源型和调峰型LNG接收终端采用再冷凝工艺和直接压缩工艺进行了能耗对比,从经济性和环境影响比较了不同的气化工艺,提出了合理选择接收终端工艺的基本原则,给出了各类接收终端的工艺选择方式。最后提出了我国LNG接收终端工艺方面需要进一步研究的问题。

The comparison and selection of LNG receiving terminal process was the key to efficient operation.For the energy consumption of gas source and peak shaving LNG receiving terminal,recondensation process was compared with direct compression process.Different gasification processes on the basis of economical efficiency and environment influence were compared.The fundamental principle for rational selection of LNG receiving terminal process was presented.Process Selection for different receiving terminals were also proposed.Some questions that should be further investigated were put forward.
