CO2 absorption is a key to alleviating the environmental consequences of fossil fuel combustion, which is a major source of global CO2 emission. Membrane contactors have showcased several competitive advantages in CO2 absorption over conventional gas–liquid contactors (e.g., packed towers), such as a large mass-transfer area and a safe operation owing to the membranes that physically separate the gas and liquid phases. This Review discusses the state-of-the-art studies related to CO2 absorption using membrane contactors, with focuses on membrane materials, liquid absorbents, process design, and pilot-scale demonstration of membrane contactor processes. Critical challenges in membrane contactor-based CO2 absorption processes, such as membrane fouling and pore wetting, are also discussed.

使用膜接触器吸收CO 2的最新进展和未来展望

吸收CO 2是减轻化石燃料燃烧对环境的影响的关键,而化石燃料燃烧是全球CO 2排放的主要来源。与传统的气液接触器(例如,填充塔)相比,膜接触器在吸收CO 2方面显示出若干竞争优势,例如较大的传质面积以及由于膜将气相和液相物理分开而使操作安全。这篇评论讨论了与使用膜接触器吸收CO 2有关的最新研究,重点是膜材料,液体吸收剂,工艺设计以及膜接触器工艺的中试规模演示。基于膜接触器的CO 2的关键挑战 还讨论了吸收过程,例如膜污染和孔润湿。
