Abstract

The aim of this work was to evaluate the performance of three different supported amine sorbents in a 6-step vacuum swing adsorption (VSA) cycle through process simulation and optimization for a representative post-combustion CO2 capture system. Detailed process optimization revealed that all the adsorbents were able to achieve the desired purity-recovery targets. The best performing adsorbent in terms of productivity was Lewatit with a productivity of 0.48 mol m−3 ads s−1. All the adsorbents exhibited similar minimum specific energy value of around 1 MJ kg−1 on an electric basis.
