摘要
介绍了几种常规的天然气液化制冷类型及方法。针对低浓度煤层气含氧液化的工艺特点,结合常规制冷液化工艺,提出一种新型含氧煤层气液化制冷系统,详细的阐述了混合冷剂系统与氮冷剂系统的冷剂循环过程。
Introduces several common natural gas liquefaction refrigeration types and methods. As for the technological characteristics of low-concentration coal-bed methane oxygenated liquefaction,combineds with common refrigeration liquefaction technology,it puts forward a new type of oxygenated coal-bed methane liquefaction refrigeration system and illustrates the refrigerant circulation process of mixed refrigerant system and nitrogen refrigerant system in detail.
