The invention relates to a process for minimizing evaporator scaling during the recovery of liquids and solids from the aqueous effluent discharged during a partial oxidation gasification from a gasifier (16), wherein the aqueous effluent contains ammonium chloride. The aqueous effluent is evaporated in an evaporator (106) to produce a distillate water line (110) and a line containing brine (112) with a brine concentration of about 10 to 60 weight percent. The brine can be further concentrated and ammonium chloride crystals are recovered. The distillate is recycled to the gasification reaction. No effluent discharges to the environment.

L'invention concerne un procédé servant à limiter au maximum l'entartrage d'un évaporateur pendant la récupération de liquides et de solides depuis l'effluent aqueux évacué pendant une gazéification à oxydation partielle depuis un gazéificateur (16), cet effluent aqueux contenant du chlorure d'ammonium. L'effluent aqueux subit une évaporation dans un évaporateur (106) afin de produire une ligne de distillat aqueux (110) et une ligne contenant de la saumure (112) concentrée à raison de 10 à 60 % en poids. On peut encore concentrer cette saumure et récupérer les cristaux de chlorure d'ammonium. On recycle le distillat vers la réaction de gazéification. Aucun effluent n'est évacué dans l'environnement.
