Post-combustion power plants are the major sources of CO2 emissions. Given that fossil fuels will be the major sources of energy in the next few years, capture of CO2 from these sources for sequestration could be a possible short term solution for abating greenhouse gas emissions. Pressure/Vacuum swing adsorption (P/VSA) processes using solid sorbents are considered as viable options.
The presentation will have two parts. In the first, we report the systematic procedure for the synthesis of a P/VSA processes for dry CO2/N2 separation using zeolite 13X as adsorbent. Using equilibrium and kinetic parameters obtained in the laboratory, we screen several processes for adsorptive post-combustion capture. Based on multi-objective we identify the process that provides the best productivity-energy consumption trade-off. This process is then scaled for pilot-plant demonstration. These represent the first reports in the open-literature of an adsorptive process that achieves the purity and recovery targets set by the US Department of Energy in a single-stage process.
The second part of the work deals with the issue of CO2 capture from wet flue gas. We report our recent results of developing a two-sorbent process for this purpose. We show that it is possible to capture CO2 from wet flue gas and discuss the additional energy that is required to achieve this.
