Performance Evaluation for a Thermal Swing Honeycomb Rotor Adsorber Using a Humidity Chart

[摘要] References(14)Cited-By(28)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 remarkably owing to the mass/heat balance limitation when the feed humidity is high or regeneration temperature is low.A prediction method is proposed for the design principle of honeycomb adsorbers by taking into account the optimal rotation speed and the regeneration air velocity obtained from the graphical solution using a humidity chart. The method 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 1 m/s, by considering the relation between the optimal rotation speed and the moderate regeneration air velocity obtained using a graphical method, the product air humidity decreases to a value near to the thermodynamic limit.
