富含CO_(2)天然气净化技术现状及研究方向

Present Situation and Research Direction of CO_(2) Rich Natural Gas Purification Technology

随着社会的发展,富含CO_(2)天然气净化技术也面临着极大的挑战,如天然气气质问题等。根据中国与其他发达国家富含CO_(2)天然气脱除CO_(2)技术的发展现状,对净化技术中的弊端作出了剖析,目前,活化甲基二乙醇胺法的吸收剂循环量大,变压吸附法等工艺也不成熟,在此背景下,提出了活化剂等技术的研究方向,希望可应用到富含CO_(2)天然气净化技术中,进而带动我国对富含CO_(2)天然气的开发使用。

With the development of society,the purification technology of natural gas rich in CO_(2)is also facing great challenges,such as natural gas temperament.According to the development status of CO_(2)removal technology for CO_(2)rich natural gas in China and other developed countries,the disadvantages of purification technology are analyzed.At present,the absorbent circulation of activated methyldiethanolamine method is large,and the processes such as pressure swing adsorption method are not mature.Under this background,the research direction of activator and other technologies is put forward,which is to be applied to the purification technology of CO_(2)rich natural gas.This will drive the development and use of CO_(2)rich natural gas in China.
