Title
(EN) METHOD(S) FOR CHANGING CONCENTRATION OF A SOLUTE WITHIN A SOLUTION
(FR) PROCÉDÉ(S) PERMETTANT DE MODIFIER LA CONCENTRATION D'UN SOLUTÉ DANS UNE SOLUTION
Abstract
(EN)
A method(s) (600, 1100) for changing concentration of a solute within a solution is disclosed. The method (600) includes receiving a first stream of the solution at a state Din by a first heat and mass exchanger HMX1 and a second stream of the solution by a second heat and 5 mass exchanger HMX2. The method (600) includes processing the first stream of the solution by the HMX1 to generate a first dilute stream of the solution at a state Dout. Further, the method (600) includes processing the second stream of the solution by the HMX2 to generate a first concentrate stream of the solution at a state Rout. The method (600) includes directing, at the initial phase, the first dilute stream of the solution from the processing unit to a first heat and mass exchanger 0 HMX1-n of a successive processing unit. The method (600) also includes receiving a first stream of the solution at a state Din-n by a second heat and mass exchanger HMX2-n.

La présente invention concerne un ou des procédé(s) (600, 1100) permettant de modifier la concentration d'un soluté dans une solution. Le procédé (600) consiste à recevoir un premier flux de la solution à un état Din dans un premier échangeur de chaleur et de masse HMX1 et un second flux de la solution par un second échangeur de chaleur et de masse HMX2. Le procédé (600) consiste à traiter le premier flux de la solution par le HMX1 pour générer un premier flux dilué de la solution à un état Dout. En outre, le procédé (600) consiste à traiter le second flux de la solution par le HMX2 pour générer un premier flux concentré de la solution à un état Rout. Le procédé (600) consiste à diriger, à la phase initiale, le premier flux dilué de la solution de l'unité de traitement à un premier échangeur de chaleur et de masse HMX1-n d'une unité de traitement successive. Le procédé (600) consiste également à recevoir un premier flux de la solution à un état Din-n par un second échangeur de chaleur et de masse HMX2-n.
