Abstract: A system for optimal pressure control in a multi-stage evaporation unit comprising two or more series connected evaporation stages with at least one of the stages preceded by a heat source, where the fresh or feed solution is passed through heat exchangers in which it is heated by means of the vapors from the subsequent evaporation stages, and where a heat exchanger adapted to permit free flow of the vapor condensate through the heat exchanger inner portion or tube portion is arranged in the line through which the vapor leaves the higher-pressure evaporation stage.
