天然气中酸性气体脱除的新方法——膜分离方法

Membrane Seperating Method—A New Method for Removing Acidic Gas from Natural Gas

本文介绍了膜分离方法的基本特点及其在天然气脱酸性气体(CO_2及H_2S)中的实际应用,并对膜分离法、传统的化学吸收法、物理吸收法脱天然气中CO_2时的费用等进行了比较。结果认为,膜法在经济上具有较大的优越性;此外,膜法还具有设备简单、结构紧凑、占地面积小、不需溶液贮存等一系列优点。因此有广阔的应用前景。

This article describes the essential features of membrane seperating method and its realistic appli- cation to remove acidic gas(CO_2 &H_2S)from natural gas, compares the cost of membrane sepcrating method with traditional chemical absorption method and physical absorption method in removing CO_2. It is recognized that membrane seperating method has widely using prospects because of a series of its advantage such as simple equipment, tight structure, fewer occupancy space, without solution storing etc.
