聚合物膜分离材料在天然气脱硫脱碳领域的研究进展
Research progress of polymer membrane separation materials in the field of natural gas desulfurization and decarbonization
摘要
Abstract
Natural gas is a clean energy source,and its CO2 emissions when burned are lower than those of other fossil fuels.Raw natural gas contains a certain amount of acidic gases such as CO2 and H2S,which must to be removed before entering the gas pipeline network.Membrane separation is a technology with a simple process and operation,which has a good application prospect in the field of natural gas desulfurization and decarbonization.The development of polymer membranes in the past 40 years,the separation mechanism and the application of membrane separation technology in the field of natural gas desulfurization and decarbonization were investigated.The types and applications of rubbery polymer membrane,glassy polymer membrane and hybrid membrane were summarized,and the application of membrane separation technology in the field of natural gas desulfurization and decarbonization was prospected.The rubbery polymer membrane has high permeability to H2S but low H2S/CH4 selectivity.The glass polymer membrane has low permeability to H2S but high H2S/CH4 selectivity.The hybrid membrane can balance permeability and selectivity by combining with functional nanomaterials,ionic liquids or deep eutectic solvent,which is the development trend of membrane separation materials in the future.关键词
