煤层气液化装置设计——N_2-CH_4混合膨胀制冷工艺

CBM Liquefaction Plant Design——N_2-CH_4 Mixed Expansion Refrigeration Process

我国煤炭资源丰富,为了保证在煤矿开采过程中的安全,大量煤层气被直接排放到大气中。通过深冷技术可以将回收的煤层气进行液化,以方便于储运和运输。本文详细介绍了山西某地拟建煤层气液化装置的设计参数和工艺流程,并分析了液化装置的流程特点。

There is abundant coal resources in China, in order to ensure the safety of coal mining process, a large number of coal bed methane is directly discharged into the atmosphere. In order to facilitate the storage and transport, through the cryogenic technology can be liquefied coalbed methane recovery. This paper describes design parameters and technological process of combed methane liquefaction plant a place in Shanxi proposed, and analyses process characteristics of the liquefaction plant.
