Possibility of toluene recovery from waste air in a cyclic TSA system has been investigated theoretically and experimentally with fixed bed of polymeric adsorbent Dowex Optipore V503. The TSA cycle is operated in three steps: an adsorption step with cold feed (i), a desorption step with hot inert gas (ii) and a cooling step with cold inert gas (iii). A non-isothermal, non-equilibrium mathematical model is developed to simulate temperature and concentration data for adsorption, desorption and cooling steps. A bench scale fixed bed adsorption unit is used for the experimental study.
