متن کاملTheoretical Study of Indirect Heating Temperature Swing Adsorption in an Adsorbent Coated Finned Tube Heat Exchanger
In this study, the performance of an adsorbent coated finned tube exchanger for carbon capture was investigated numerically. The results showed that this structure has a great potential for being applied as a medium for CO2 capture by rapid indirect thermal swing adsorption. By using this structure, the recovery of 96%, and purity of 98% were achieved with a simple cycle consisting of two steps...
