摘要
结合国内实际生产运行的LNG液化装置,介绍级联式制冷工艺、膨胀制冷工艺和混合制冷工艺的特点,讨论新开发的混合制冷工艺,进行混合制冷工艺的比较,分析比较了各种天然气液化工艺的能耗和液化循环特性。
Considering the LNG liquefaction devices used in China, the characteristics of cascade refrigeration process, expansion refrigeration process and mixed refrigeration process are introduced. The newly developed mixed refrigeration process is discussed, and the mixed refrigeration processes are com- pared. The energy consumption and liquefaction cycle characteristics of different natural gas liquefaction processes are analyzed and compared.
