ÉTUDE D'UN PROCÉDÉ D'ADSORPTION TSA (Temperature Swing Adsorption)
À CHAUFFAGE ET REFROIDISSEMENT INDIRECTS

Abstract : This work deals with a new TSA (Temperature Swing Adsorption) process for gas purification or recovery. This new process uses an adsorber equipped with an internal heat exchanger. The heating step (desorption) is achieved by steam condensation. During the cooling step (adsorption), city network water circulates through the heat exchanger. An experimental study with mono or multicomponent (CO2 and/or C2H6) feeds showed that, owing to a fast heating of the adsorber, highly concentrated products are recovered at the outlet. The local behavior of this new adsorber was compared with that of a conventional TSA adsorber by means of numerical simulation, which was firstly validated from experimental results. During the adsorption step, the feed temperature and the initial bed temperature have only minor influence on the new adsorber performances. During the desorption step, a high heating temperature results in a short step duration, contrarily to the conventional adsorber case. Thanks to a parametric study on cycle operations, a range of operating conditions (desorption temperature, purge flow rate) was defined for one specific application. Lastly, a feasibility study on toluene capture was achieved in order to evaluate the potential of this new process for the volatile organic compound (VOC) removal. The high enrichment (160) obtained during desorption, allows to increase the dewpoint temperature, which will facilitate the final VOC recovery.
