中文摘要：

介绍了一种新型的从沼气中分离高纯甲烷气的水合物法,并与传统的分离方法,即变压吸附法、吸收法、膜分离法,干法脱硫、湿法脱硫和生物脱硫等方法进行了比较,具有显著的高效性和经济性。设计了水合物法分离高纯甲烷气的系统装置。

英文摘要：

The separation of high pure methane from biogas by hydrate method was introduced in this paper,and its advantages were compared with conventional methods including pressure swing adsorption method,absorption method,membrane separation method,dry desulphurization,wet desulphurization and biological desulphurization,and showed theoretically high efficiency and economic.A setting of hydrate method separating high pure methane from biogas was designed.
