(276a) Multi-Scale Screening of Porous Materials for Carbon Capture
AIChE Annual Meeting
Tuesday, October 31, 2017 - 8:00am to 8:22am
In this study, a 4-step vacuum swing adsorption (VSA) cycle described in earlier publications4,5 was employed in this work to evaluate the performance of two adsorbents namely zeolite 13X and CPO-27-Ni metal organic framework. The information on adsorption equilibrium and kinetics were obtained from lab scale volumetric experiments as well as molecular dynamics simulations. Detailed optimization of the 4-step VSA cycle was carried out using non-dominated sorting genetic algorithm (NSGA-II) to arrive at operating conditions that satisfy 95% CO2 purity and 90% CO2 recovery with minimum energy consumption and maximum productivity. The performance of the VSA process was evaluated using both the actual experimental data and predictions from molecular simulations and we demonstrate the differences in the performance of the materials in a VSA process in the two cases.
