The subject of this investigation is a recently developed Electric Swing Adsorption (ESA) system (adsorption cycle with electrothermal desorption step, which is performed by direct heating of the adsorbent particles by passing electric current through them), with an adsorber assembled of two annular, radial-flow, cartridge-type fixed-beds, with in-vessel condensation.

Three FEMLAB models were built, in order to describe three stages of a compete ESA cycle: adsorption, electrothermal desorption before the start of condensation and electrothermal desorption with in-vessel condensation In order to describe the complete ESA cycle the models for the three stages were integrated, by using a combination of FEMLAB and MATLAB.

The models were successfully used for simulation of separate stages of the process and of the complete ESA cycles, as well as for their optimization.
