对南海西部气区高含碳天然气脱碳方法的初步筛选

Initial Approach to Decarbonization of High Carbon Natural Gas for Nanhai Weat Major Gas Region

本文对天然气中CO_2的脱除方法进行了简介,并针对南海西部气区高含碳天然气的气质条件,对初步筛选出的三种可行的方法(活化MDEA法,Selexol法和渗透膜法)进行了描述,并对其优缺点进行了评估。结论认为活化MDEA法或Selexol法是较适宜采用的方法。

This paper briefly introduces the relieving method of CO2 in natural gas, describes the three feasible methods-activation MDEA, selexol and permeable membrane screened initially, aiming at the special condi-tion of high carbon natural gas in Nanhai west major gas region, and evaluates their advantages and disadvan-tages. The conclusion holds that utilizing activate MDEA or selexol are suitable.
