(225p) An Optimised Vacuum Pressure Swing Adsorption System for CO2 Capture

We have developed and constructed a robust Equilibrium Theory model for analysing a complex Pressure Swing Adsorption cycle that may include multiple pressure equalization, co-current depressurization, light and heavy refluxes, feed and product pressurization, etc.^1,2.

In this study, it is aimed to make the most of the theoretical model for estimating qualitatively the performances of various Vacuum Pressure Swing Adsorption (VPSA) systems designed for CO₂ capture and ultimately optimize them for maximum feed throughput.
