Salt from waste heat
In areas where solar evaporation is insufficient for the purpose of salt production, the evaporation rate can be enhanced by utilising waste heat.
Conventional thermal salt evaporation processes employ expensive heat at temperatures well above 100°C. The THERMOSAL process utilizes residual waste heat for enhanced brine evaporation. Waste heat can be obtained from the cooling system of power generators, from processing plants or incinerators. It is inexpensive and ecological. The heat magnifies the evaporation rate of brines in open ponds and accelerates salt crystallisation. The starting material is saturated brine or sea water, rock salt or any other low quality salt. The pure crystal salt produced with the THERMOSAL process can reach vacuum salt quality at significantly lower cost.
