PCT No. PCT/SE96/00542 Sec. 371 Date Nov. 12, 1997 Sec. 102(e) Date Nov. 12, 1997 PCT Filed Apr. 24, 1996 PCT Pub. No. WO96/34235 PCT Pub. Date Oct. 31, 1996A process of improving the heat efficiency by condensation of vapor in concentrated chemical solutions, according to which vapor and a concentrated chemical solution are introduced into an absorber comprising a cooler/condenser. In accordance with the invention, the condensate formed in the condensation process is utilized to dilute the concentrated chemical solution in the absorber, and the heat of condensation and the heat of solution generated from the dilution step are recovered by heat exchanged thereof with a heat-absorbing medium. A plant for performing the process is described, comprising an absorber (1) and a cooler (condenser) associated therewith, and at least one heat exchanger (3) having an inlet and an outlet for supply and withdrawal of a heat-absorbing medium. The plant has at least one inlet to the absorber (1) for supply of concentrated chemical solution, at least one inlet to the absorber (1) for supply of vapor, and at least one outlet from the absorber for withdrawal of a diluted chemical solution obtained through condensation of vapor and the chemical solution in the absorber (1). |
