Abstract

Before evaporation, the effluent is pre-heated and then distilled, the heat of distillation being recovered in the evaporative process, which is pref. carried out in a multistage evaporation plant, during which the vapour is treated with an alkaline solution, e.g. by washing in the separator of each evaporator stage, so that the final condensate has a C.O.
