【摘要】 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（CO₂及H₂S）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CO₂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。更多还原

【Abstract】 This article describes the essential features of membrane seperating method and its realistic appli- cation to remove acidic gas（CO₂ &H₂S）from natural gas, compares the cost of membrane sepcrating method with traditional chemical absorption method and physical absorption method in removing CO₂. 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.更多还原
