Abstract
A process for introducing a solution into an evaporative cooling apparatus (14), said process comprising a) positioning a selectively permeable membrane (16) between a first solution (18) and a second solution (20) having a higher solute concentration than the first solution (18), such that the solvent from the first solution (18) flows across the selectively permeable membrane (16) to dilute the second solution (20), b) introducing the second solution into an evaporative cooling apparatus (14) in which solvent is removed from the second solution (20) by evaporation, and c) recycling the second solution (20) from step b) to step a) to draw solvent from the first solution (18).
Claims15
A process for introducing a solution into an evaporative cooling apparatus, said process comprising the steps of:
- a) providing a first solution selected from the group consisting of seawater, brackish water, river water and waste water,
- b) forming a second solution by dissolving a solute in water having a higher solute concentration than the first solution,
- c) positioning a selectively permeable membrane between a first solution and a second solution having a higher solute concentration than the first solution, such that the solvent form the first solution flows across the selectively permeable membrane to dilute the second solution,
- d) introducing the second solution into the evaporative cooling apparatus in which solvent is removed from the second solution by evaporation, and
- e) recycling the second solution from step d) to step c) to draw solvent from the first solution.
