LNG调峰装置工艺技术及对比研究

摘要

介绍了某燃气公司LNG调峰装置的工艺流程,着重对LNG调峰装置在天然气预处理、液化、制冷循环方面进行了详细说明,并与国内已建成LNG装置的液化工艺进行了对比,分析了各个液化工艺的特点和适用范围,提出了基本负荷型天然气液化装置和调峰型天然气液化装置工艺流程的选择原则,为以后LNG装置的建设和发展提供了技术参考.%The technique process of LNG peak - shaving plant was described, especially with emphasis on the natural gas pre - processing, liquefaction and its refrigeration cycle. It analysed characteristics of each liquefied technology and scope of application. Selection principle of technological process of natural gas liquefaction plants of basic load type and peak shaving type were given after comparing with liquefied technologies of LNG plants built in China. It can provide technical reference for the future construction and development of LNG plant.
