Hybrid membrane cryogenic process for post-combustion CO2 capture
TL;DR: In this article, the potential for a hybrid process combining membrane and cryogenic separation to achieve efficient post-combustion carbon capture has been investigated through a simulation study, which combines a first step CO2 pre-concentration with a membrane unit and a second step CO 2 cryogenic condensation.

An energetic analysis of CO2 capture on a gas turbine combining flue gas recirculation and membrane separation
TL;DR: In this paper, the possibility to achieve carbon capture on a gas turbine, based on a combination of flue gas recycle and membrane separation is reported, and an overall energy requirement down to 26 GJ per ton can possibly be achieved when optimal operating conditions based on oxygen enriched air (OEA) combustion together with a highly selective membrane (CO 2 /N 2 selectivity of 200) are combined.

CO2 capture for gas turbines: an integrated energy-efficient process combining combustion in oxygen-enriched air, flue gas recirculation, and membrane separation
TL;DR: In this paper, a hybrid process based on oxygen enriched air combustion, flue gas recycling and CO2 capture by membranes is explored for a 250 MW open cycle gas turbine, and it is shown that an overall energy requirement below 2 GJ(th)/ton of CO2 captured (i.e. around 205 kWh(electrical)/ton CO2) can be achieved using a highly selective membrane (CO2/N-2 selectivity of 200) operated under optimal process conditions.

Membrane gas separations and post-combustion carbon dioxide capture: Parametric sensitivity and process integration strategies
TL;DR: In this article, a systematic analysis of the energy requirement of a single stage membrane gas separation module has been performed and different inlet CO2 contents and membrane selectivity performances have been compared.
