Title:
NON-HEAT-INSULATED DISTILLATION COLUMN
Document Type and Number:
WIPO Patent Application WO/2019/176188
Kind Code:
A1
Abstract:
A non-heat-insulated distillation column 1 has: first and second cooling devices 11, 12 which indirectly cool fluid within a concentration section 2 by means of a circulating operating fluid; first and second heating devices 21, 22 which indirectly heat fluid within a recovery section 3 by means of circulating operating fluid; a first compressor 31 which, in first circulation passages P11-P14 between the first cooling device 11 and the first heating device 21, compresses an operating fluid from the first cooling device 11; a second compressor 32 which, in second circulation passages P21-P24 between the second cooling device 12 and the second heating device 22, compresses an operating fluid from the second cooling device 12; a first expansion device 41 which, in the first circulation passages P11-P14, expands an operating fluid from the first heating device 21; and a second expansion device 42 which, in the second circulation passages P21-P24, expands an operating fluid from the second heating device 22.
