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 vapor-liquid phase separation in solution concentrating processes with the vapor phase utilized as supplemental heating medium to the solution to be concentrated; incorporation of a counterflow gas-liquid contact stage (cooling tower) as one phase in processes of concentrating heated solutions.
