Comparison Of Membrane-Based Pre- And Post-Combustion CO2 Capture Options Applied In Energy-Intensive Industrial Applications

Abstract

Deployment of decarbonization technologies in energy-intensive industrial applications (e.g., heat and power, metallurgy, cement, chemical sectors etc.) is of great importance for reducing CO2 emission and achieving global climate neutrality. Membrane CO2 removal systems gained relevant attention as possible energy and cost-efficient CO2 capture technology. This paper is evaluating membrane-based pre- and post-combustion CO2 capture to be applied in various industrial applications with high fossil CO2 emissions. The evaluation was geared mainly towards quantification of ancillary energy consumptions of membrane systems as well as the specification of captured CO2 in respect to its potential utilization and storage applications. As the assessment show, the membrane-based systems are promising CO2 capture technology for both pre- and post-combustion capture configurations.
