EXPERIMENTAL-STUDY OF OPTIMAL OPERATION FOR A HONEYCOMB ADSORBER OPERATED WITH THERMAL SWING

A new example of thermal swing adsorption using a honeycomb rotor with a thin sheet of silica gel ss adsorbent has been developed for dehumi dification of air. Owing to improvement in the dynamic adsorption capa city and rapid thermal response of the rotor, the product humidity was reduced to 10-20 % of the feed at an air velocity of 1-2m/s through a 0.2m-long honeycomb. The existence of an optimal rotation speed of ro tor has been observed. It increased in proportion to a single term of velocity of regeneration air, divided by width of the rotor and bulk d ensity of the rotor; the effects of temperature and humidity of the fe ed and regeneration air were small. A dimensionless formula for the op timal rotation speed was derived on an empirical basis.
