Abstract:
The use of "Solar Brine Evaporators" in the production of natural sodium sulfate has been investigated. Three types of evaporators were used; "open" , "closed" and "closed with suction". Evaporation efficiencies for all three types of evaporatorshave been determined. Experimental results based on small scale evaporators using thin film evaporation, have succeeded in in creasing brine concentrations from 5% to 30%. As a result crystal production capacity increased by 55%. For large scale applications due to ease of operation "open" type evaporators must also be considered although their evaporation efficiencies were not as high as the other two types.
