In recent years attempts have been made to use packed lowers for regen
erating weak liquid desiccants in desiccant cooling or drying processe
s. For regeneration of desiccants, a counter-flow packed regeneration
tower in conjunction with a humidifier has been designed and construct
ed. The tower was packed with plastic Intalox Snowflake packing materi
al. Experimental measurements of the regeneration tower performance ut
ilizing a new cost effective liquid desiccant mixture CELD (comprised
of 50% of lithium chloride and 50% calcium chloride by weight) have be
en carried out. The average summer climatic conditions for Oklahoma (d
ry-bulb temperature of 32.22-degrees-C and relative humidity of 60%),
Texas (dry-bulb temperature of 32.22-degrees-C and relative humidity o
f 70%), and Florida (dry-bulb temperature of 32.22-degrees-C and relat
ive humidity of 80%) were simulated with air inlet condition to the to
wer. The effect of desiccant inlet temperature, inlet concentration, a
nd flow rate on the regeneration tower performance has been investigat
ed.
