ABSTRACT:
A direct contact condenser of a distillation system has a condenser vessel comprising a vapor space with a vapor inlet, a condensate pump, with the liquids' level defining the top of the sump and the bottom of the vapor space. The thermal efficiency of the system is improved wherein the heat of condensation is concentrated in one of two coolant effluent lines while the other coolant line removes unheated excess liquid coolant. This is accomplished with the use of two temperature sensors at spaced vertical locations of the sump and a liquid level control together regulating the opening and closing of respective valves in respective influent and effluent lines of the sump.
