二氧化碳、甲烷分离工艺述评

Review of Separation Processes of Mixed Carbon Dioxide and Methane Gas

以鹤壁新区地热资源开发所发现的伴生二氧化碳、甲烷的分离回收问题为背景 ,介绍了深冷分离、变压(温 )吸附分离、吸收—解吸分离、膜分离以及这些技术的联合工艺 。

The separation and recovery of carbon dioxide and methane from associated gas discovered during exploration of terrestrial heat in Hebi area is discussed. The separation processes such as cryogenics,absorption-desorption,membrane and combination of these processes are introduced . The characteristics of each process is reviewed.
