Carbon capture by hybrid separation processes

Even though there is an increasing development of carbon capture technology over the last decade, large-scale implementation is still far from common practice, mainly caused by the energy intensiveness of carbon capture processes and the lack of regulation. In absence of strict regulation, less energyintensive CO2 capture processes are a must to facilitate the implementation of carbon capture technology. This paper addresses the need for cheap carbon capture technology and introduces the process of Condensed Rotational Separation as a compact fast pressure-distillation technique for purification and separation of CO2 from coal combustion related effluent. CO2 separation targets are identified, hybrid process combinations with membranes and oxyfuel are introduced and a case study is discussed to compare hybrid CRS processes with the conventional standard of amine scrubbing. Hybrid CRS processes have potential to reduce the CO2 capture energy penalty by more than half, compared to MEA absorption.
