ABSTRACT:
Adiabatic self-evaporation cooling of a refrigerant is performed in a crystallizer for a treated organic matter which contains the refrigerant and is fed into the crystallizer. Crystals produced by the adiabatic self-evaporation cooling are withdrawn from the crystallize. An evaporated vapor is introduced from the crystallizer into an absorber so as to be contacted with a concentrated solution transformed from a generator for condensation in the absorber. A condensate is introduced from the absorber into the generator, the refrigerant is evaporated in the generator, an evaporated vapor is introduced from the generator to the condenser, the evaporated vapor is condensed in the condenser, a condensate is supplied from the condenser to the crystallizer and the concentrated solution is circulated between the absorber and the generator by returning the concentrated solution, in which the concentration of an absorbent is increased by the generator to the absorber.
