ABSTRACT:
Improvements in the concentration of solutions in processes involving heating the solution to be concentrated; Processes of solution concentrating where the solution to be concentrated is heated prior to concentration by either direct or indirect heat exchange, including particular concentrating processes where the heating means and media include: (1) high pressure steam; (2) low-pressure steam and (3) submerged combustion; Improved methods of producing and utilizing vapor-liquid phase separation(s) in solution concentrating processes with the vapor phase(s) utilized as a supplemental heating medium applied to the solution to be concentrated; Incorporation of a plurality of counterflow gas-liquid contact stages (cooling towers) as two phases in processes of concentrating heated solution; Utilization in coordination of a plurality of cooling towers and at least one water heater in processes of concentrating heated solutions.
