EXPERIMENTAL-STUDY ON THE PERFORMANCE OF A REGENERATION TOWER FOR VARIOUS CLIMATIC CONDITIONS

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.
