Title:
A DISTILLATION SYSTEM AND A DISTILLATION METHOD
Document Type and Number:
WIPO Patent Application WO/2009/094895
Kind Code:
A1
Abstract:
A distillation system comprises a generator (11), a condenser (12), an evaporator (13), an absorber (14), a crystallizer (141) for absorbent and a distillation column (410). The heat exchanger (140) of the absorber (14) connects with the heat exchanger (110) of the generator (11) to form a heat circulation loop, which was used to transfer the heat produced by the absorber (14) to the generator (11). The absorbing solution inlet of the crystallizer (141) for absorbent connects with the absorbing solution outlet of the absorber (14). The outlet of after-crystallization absorbing solution of the absorbent crystallizer (141) for absorbent connects with the absorbing solution inlet of the generator (11). The crystal outlet of the crystallizer (141) for absorbent connects with the absorbing solution inlet of the absorber (14). The overhead product line (402) of the distillation column (410) connects with the heat exchanger (130) of the evaporator (13) to form an overhead circulation loop, while the bottom product line (404) of the distillation column (410) connects with the heat exchanger (120) of the condenser (12) to form a bottom circulation loop. A distillation method uses the distillation system.
