Abstract
Conventional CO2 capture technologies are well-established for CO2 separation in power plants and carbon emission industries. However, the additional operating expenses under optimized conditions remain a problem that leads to increased production costs. Therefore, it is necessary to evaluate the viability of CO2 capture technologies based on their energy consumption and processability. This review focuses on the economic feasibility of membrane-based CO2 capture and comparison with existing technologies, with particular attention to the costs of CO2 capture and its removal efficiency. On this basis, technology limitations and challenges will be further discussed based on the operational configuration. The output of the technical and economic evaluations concluded that membrane gas absorption (MGA) is the most feasible, has relatively low operating costs, and is easy to operate at room condition, which implies the potential of MGA as an alternative approach to mitigate CO2 emissions. In addition, this review also clarifies the development of superhydrophobic membranes in MGA, so that MGA can reach another higher level in industrial-scale applications.

对二氧化碳捕获膜气体吸收技术经济分析的批判性评论
摘要
传统的 CO 2捕集技术在发电厂和碳排放行业的 CO 2分离方面已得到广泛应用。然而,优化条件下的额外运营费用仍然是导致生产成本增加的问题。因此,有必要根据其能耗和可加工性来评估CO 2捕集技术的可行性。本综述重点关注基于膜的 CO 2捕获的经济可行性以及与现有技术的比较,特别关注 CO 2的成本捕获及其去除效率。在此基础上,将根据运行配置进一步讨论技术限制和挑战。技术和经济评估的结果表明,膜气体吸收 (MGA) 是最可行的,具有相对较低的运行成本,并且易于在室温条件下运行,这意味着 MGA 作为一种替代方法来减少 CO 2的潜力排放。此外,本综述还阐明了超疏水膜在MGA中的发展,使MGA在工业规模应用中达到另一个更高的水平。
