Abstract

In this paper we address the design and optimization of a pressure/vacuum swing adsorption (P/VSA) process for the post combustion capture of CO2. HKUST-1, Ni/DOBDC, zeolite 5A and zeolite 13X are considered as potential adsorbents for the P/VSA system. A detailed simulation is set up and then optimized using a nondominant sorting genetic algorithm. This is coupled with an upstream dehydration unit to allow the impact of the presence of water to be analysed. The results show that for both the dry and wet flue gas, zeolite 13X has the lowest overall cost for capturing CO2, with a cost of $22.91 / ton of CO2 captured and $23.38 / ton of CO2 captured, respectively.
