MODELING OF DRYING OF GASEOUS MIXTURES IN TSA SYSTEM WITH FIXED BED OF SOLID DESICCANTS
A nonisothermal, nonequilibrium mathematical model was developed to analyze theoretically adsorptive drying of gaseous mixtures, containing water and volatile organic compound (VOC).The analysis concerns four beds cyclic temperature swing adsorption (TSA) system.The two fixed beds are formed of silica gel primarily as the water vapor adsorbent.The others two consist of activated carbon mainly as adsorbent of the organic component (benzene).In the model, possible insignificant interactions among VOC and water during adsorption and desorption, were neglected.The following parameters were considered to study its effect on the process efficiency: relative humidity of the inlet gas, temperature of the purge gas and height of the adsorbents beds.The results of simulations showed, that both the adsorption isotherms and temperature effects play an important role in the breakthrough behavior.
