This study analyzes the e2ect ofan operating parameter on the dynamic behavior by performing dynamic simulations ofcyclic
thermal swing adsorption (TSA) system, in 3xed beds packed with activated carbon as an adsorbent. This TSA process puri3es and regenerates the ternary mixtures consisted ofbenzene, toluene and p-xylene. A mathematical model, considering the dynamic variation and spatial distribution ofproperties within the bed, has been formulated and described by a set ofpartial di2erential algebraic equations. The models are based on non-equilibrium, non-isothermal and non-adiabatic conditions. The breakthrough curves ofour simulation model are compared with those ofYun’s experiments (1999). The cyclic steady-state (CSS) cycles are obtained for the various cases by cyclic simulation. The in8uences of the purge gas temperature on breakthrough curves, CSS convergence time, cyclic operating step time, purge gas consumed, regeneration energy requirement and adsorption ability at CSS are also discussed.
