Chapter 10 - Application of membrane technology for CO2 capture and separation

Abstract

CO2 capture using membrane technology has received much attention compared to the traditional gas separation technologies such as amine adsorption and cryogenic distillation because of simplicity, scalability, and low carbon. Carbon capture and storage involves two strategies: post-combustion CO2 capture from the flue gas of fossil-fueled power plants and pre-combustion CO2 capture from natural gas, syngas, and biogas. Firstly, the fundamentals of gas transport through polymeric and inorganic membranes are elucidated in this chapter. Secondly, the membrane preparation strategies, modifications methods in polymeric membranes (e.g., polymer blends and mixed matrix membranes), and inorganic membranes (e.g., carbon molecular sieve membranes, ceramic membranes, and zeolite membranes) are reviewed. Lastly, prospects of membrane separation for CO2 capture are discussed.
