Physical solvents and techno-economic analysis for pre-combustion CO2 capture: A review

Abstract

This manuscript reviews the use, development, and economic performance of physical solvents for pre-combustion CO2 capture from high pressure H2 rich syngas streams. Commercially available physical solvents are presented, followed by an assessment of the ideal properties that are important for development of novel solvents for CO2 capture from high-pressure syngas streams. To compare the technical and economic performance of traditional and novel physical solvents, a review of the methods, assumptions and models used in techno-economic analysis (TEA) studies was conducted. It was found that, although some novel solvents show promising technical performance in the laboratory (e.g., high CO2 a..
