PERFORMANCE EVALUATION FOR A THERMAL SWING HONEYCOMB ROTOR ADSORBER USING A HUMIDITY CHART

Adsorption/desorption behavior and simultaneous heat and mass transfer in a honeycomb adsorber were investigated using a humidity chart, It was found that the dehumidifying performance is sometimes decreased re markably owing to the mass/heat balance limitation when the feed humid ity is high or regeneration temperature is low. A prediction method is proposed for the design principle of honeycomb adsorbers by taking in to account the optimal rotation speed and the regeneration air velocit y obtained from the graphical solution using a humidity chart, The met hod is simple to use, without complicated computation and it is useful to avoid the serious influence of by the mass/heat balance limitation , At a process air velocity of 1m/s, by considering the relation betwe en the optimal rotation speed and the moderate regeneration air veloci ty obtained using a graphical method, the product air humidity decreas es to a value near to the thermodynamic limit.
