ABSTRACT:
Disclosed herein is a process for disposing of aqueous sewage and for producing fresh water by coking the sewage in the liquid phase to form gases, coke and an effluent which is extracted with a hot liquid hydrocarbon to form a hydrocarbon-water solution and a hot concentrated brine. The hot brine is injected into the sewage sludge to heat same to coking temperature. Hot water is removed from the hydrocarbon-water solution, used for space heating or the like and thereby cooled. The cool water then is passed through a carbon absorber to remove traces of hydrocarbon dissolved therein, and chlorinated to give potable water.
