Method(s) for changing concentration of a solute within a solution

A method for changing concentration of a solute within a solvent, the method comprising:

• receiving a first stream of the solution at a state Din by a first heat and mass exchanger HMX1 of a processing unit;
• processing the first stream of the solution by the HMX1 to generate a first dilute stream of the solution at a state Dout, wherein the HMX1 includes a first desiccant which absorbs a first amount of the solute from the first stream of the solution at an initial phase;
• directing, at the initial phase, at least a portion of the first dilute stream of the solution from the HMX1 to a second heat and mass exchanger HMX2 of the processing unit;
• and
• processing, by the HMX2, at least the portion of the first dilute stream to generate a concentrate stream of the solution at a state Rout.

The method for changing concentration of a solute within a solution, the method comprising:

• receiving a first stream of the solution at a state Din by a first heat and mass exchanger HMX1 of a processing unit from among a plurality of processing units and a second stream of the solution at the state Rin by a second heat and mass exchanger HMX2 of the processing unit;
• processing the first stream of the solution by the HMX1 to generate a first dilute stream of the solution at a state Dout, wherein the HMX1 includes a first desiccant which absorbs a first amount of the solute from the first stream of the solution at an initial phase;
• processing, at the initial phase, the second stream of the solution by the HMX2 to generate a first concentrate stream of the solution at a state Rout, wherein the HMX2 includes a second desiccant which releases a second amount of the solute within the second stream of the solution at the initial phase;
• directing, at the initial phase, the first concentrate stream of the solution at the state Rout from the processing unit to a second heat and mass exchanger HMX2-n of a successive processing unit from among the plurality of processing units;
• processing, at the initial phase, the first concentrate stream of the solution by the HMX2-n of the successive processing unit to generate a dilute stream of the solution at a state Dout-n;
• receiving a first stream of the solution at a state Rin-n by a first heat and mass exchanger HMX1-n of the successive processing unit;
• and
• processing, at the initial phase, the concentrate stream of the solution by the HMX2-n of the successive processing unit to generate the second concentrate stream of the solution at a state Rout-n, wherein an amount of the solute within the second concentrate stream of the solution at the state Rout-n is higher than an amount of the solute within the second stream of the solution at the state Rout.

The method for changing concentration of a solute within a solution, the method comprising:

• receiving a first stream of the solution at a state Din by a first heat and mass exchanger unit HMX1 of a processing unit from among a plurality of processing units;
• processing the first stream of the solution by the HMX1 of the processing unit to generate a first dilute stream of the solution at a state Dout, wherein the HMX1 includes a desiccant which absorbs a first predefined amount of the solute from the first stream of the solution;
• directing the desiccant from the HMX1 to a second heat and mass exchanger HMX2 of the processing unit and a concentrate stream of the solution at a state Rin1 to the HMX2;
• processing the first concentrate stream of the solution by the HMX2 to generate a first concentrate stream of the solution, wherein the desiccant received by the HMX2 releases at least the first predefined amount of the solute which is being absorbed/adsorbed from the first stream of the solution in the HMX1;
• directing the desiccant from the HMX2 to a third heat and mass exchanger HMX3 of the processing unit and at least a portion of the first dilute stream of the solution at the state Dout from the HMX1 to the HMX3;
• processing at least the portion of the first dilute stream of the solution by the HMX3 to generate a second concentrate stream of the solution, wherein the desiccant received by the HMX3 from the HMX2 releases at least a second predefined amount of the solute which is being absorbed/adsorbed from the first stream of the solution in the HMX1;
• and
• directing the desiccant from the HMX3 to the HMX1 of the processing unit, wherein the desiccant re-absorbs a second amount of the solute from another stream directed in the HMX1.
