CA 2203242

The invention relates to a process for the final evaporation of black liquor in at least two evaporation appliances which are of a known construction. These appliances are coupled in series with respect to the black liquor and in parallel with respect to the live steam (primary steam) which drives the evaporation, with the steam (secondary steam) which is generated by the evaporation being in open communication in both or all of the appliances. The invention is characterized in that the pressure of the primary steam which is supplied to the appliance(s) in which the liquor is at the highest concentration is greater than that at which the primary steam is supplied to the other appliance(s).

Procédé pour l'évaporation finale d'une liqueur noire dans au moins deux appareils d'évaporation de type connu. Ces appareils sont montés en série par rapport à la liqueur noire, et en parallèle par rapport à la vapeur vive (vapeur primaire) assurant l'évaporation, la vapeur (secondaire) produite par l'évaporation étant mise en communication libre dans les deux ou tous les appareils. Le procédé est caractérisé en ce que la pression de la vapeur primaire alimentant le ou les appareil(s) dans le(s)quel(s) la concentration de liqueur est la plus forte est supérieure à celle de la vapeur primaire alimentant l'autre ou les autres appareil(s).
