Abstract

Capture of CO2 from flue gas streams using adsorption processes must deal with the prospect of high humidity streams containing bulk CO 2 as well as other impurities such as SO x , NO x , etc. Most studies to date have ignored this aspect of CO 2 capture. In this study, we have experimentally examined the capture of CO2 from a 12% synthetic flue gas stream at a relative humidity of 95% at 30∈°C. A 13X adsorbent was used and the migration of the water and its subsequent impact on capture performance was evaluated. Binary breakthrough of CO2/water vapor was performed and indicated a significant effect of water on CO2 adsorption capacity, as expected. Cyclic experiments indicate that the water ..
