Development of novel tertiary amine absorbents for CO2 capture

Abstract

In the framework of the COCS (Cost Saving CO2 Capture System) project we continue to develop high performance CO2 absorbents to reduce the regeneration energy cost to almost half the current cost. To achieve this target we investigated twenty five tertiary amine based CO2 absorbents with different chemical structures. Solvent selection procedures were carried out based on their CO2 absorption rate, loading capacity and heat of reaction measurements. We found several high performance absorbents with advantages of high absorption rate and low heats of reaction compared to MDEA.
