Membrane contactors using microporous membranes for acid gas removal have been extensively reviewed and discussed. The microporous membrane acts as a fixed interface between the gas and the liquid phase without dispersing one phase into another that offers a flexible modular and energy efficient device. The gas absorption process can offer a high selectivity and a high driving force for transport even at low concentrations. Using hollow fiber gas-liquid membrane contactors is a promising alternative to conventional gas absorption systems for acid gas capture from gas streams. Important aspects of membrane contactor as an efficient energy devise for acid gas removal including liquid absorbents, membrane characteristics, combination of membrane and absorbent, mass transfer, membrane modules, model development, advantages and disadvantages were critically discussed. In addition, current status and future potential in research and development of gas-liquid membrane contactors for acid gas removal were also briefly discussed.
微孔膜接触器用于酸气去除已经得到了广泛的综述和讨论。微孔膜作为气相和液相之间的固定界面，不会将一相分散到另一相，提供了一种灵活的模块化和节能的装置。气体吸收过程即使在低浓度下也能提供高选择性和高传质驱动力。使用中空纤维气液膜接触器是一种很有前途的替代传统气体吸收系统的方法，可用于从气流中捕集酸性气体。作为一种有效的酸气去除节能装置，膜接触器的重要方面包括液体吸收剂、膜特性、膜与吸收剂的结合、传质、膜组件、模型开发、优缺点等方面进行了批判性讨论。此外，还简要讨论了酸气去除用气液膜接触器的研究和开发的现状和未来潜力。
