摘要： The invention relates to a method for preparing an aqueous solution, in particular a sodium hydroxide solution by means of a multi-stage evaporation. Product streams (4, 5), in particular concentrate streams or vapour condensate are produced from the aqueous solution, (in the form of a hot feed solution (L)). The feed solution stream is divided between two evaporation devices A and B. During the multi-stage evaporation, the feed solution that is supplied to device A is concentrated to form a first concentrated product solution (C1). Preferably, device A represents a last stage of the multi-stage evaporation and the feed solution is conducted through additional evaporation stages (10) in the opposite direction to the vapour (Bi). Vapours (Bi) of the multi-stage evaporation are liquefied to produce vapour condensates (Ki). A fraction of said vapours (B5) is liquefied in device B to provide heating energy. A second concentrated product solution (C2) is produced in device B. According to the invention, the concentrations of said product solutions (C1, C2) do not differ by more than 20 % in relation to the higher concentration. Preferably, the first concentrated product solution (C1) has a lower concentration.

摘要： Disclosed are both an apparatus and method for the radiation-augmented electrolytic production of alkali metal hydroxide, molecular halogen, and hydrogen. A concentrated aqueous solution of NaCl and IrCl6-2 is conveyed to photolysis cell (10). Solar radiation is introduced into the photolysis cell by means of solar concentrator (20). To ensure that the photolytic reaction proceeds, the chlorine evolved must be swept from the photolytic solution and conducted away from the cell to chlorine storage vessel (30). The IrCl¿6?-3 produced in the photolysis step, in solution with NaCl, is mixed with a stream of HCL and conducted to the anode chamber of electrolysis cell (50). The NaOH/H¿2?O/H2 stream from the cathode cell is conveyed to gas separator (60), where the H2 is separated from the liquid stream and is conveyed to hydrogen storage vessel (70). The circulating aqueous NaOH solution is conveyed through recycle valve (80) to the cathode chamber of electrolysis cell (50). A portion of the NaOH solution from gas separator (60) is diverted to evaporator (90) by means of recycle valve (80). In the evaporator, thermal energy recovered in heat exchanger (40) is used to provide the heat necessary to evaporate the liquid water. The resultant concentrated solution of NaOH is conveyed to caustic soda storage vessel (100).

摘要： A method for concentrating an aqueous caustic alkali produced by a membrane cell process by using a single or multiple effect evaporator system in which the vapor flows in a counter direction to the aqueous caustic alkali flow and the heat recovered from the catholyte circulation line is used as part of the concentration process. In one embodiment, a catholyte heat recovery heat exchanger and evaporation chamber are located after the last effect of a multiple effect evaporator system. In another embodiment, the catholyte heat recovery heat exchanger and evaporation chamber are located prior to the single or multiple effect evaporator system. In yet another embodiment, the catholyte heat recovery process is used in conjunction with additional heat exchanger processes to further concentrate the final product as desired.
