Title:
ORGANIC SOLVENT RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/021637
Kind Code:
A1
Abstract:
Disclosed is an organic solvent recovery system provided with a configuration capable of reducing energy used in the organic solvent recovery system. In the organic solvent recovery system (1B), the performance of a concentration device (20) is improved by lowering the concentration rate, so that the increase (28°C→40°C) of the cooling temperature of a cooler (300) and the increase (33°C→70°C) of the introduction temperature of a gas supply/heating device (500) become possible, and the utility consumptions of the cooler (300) and the gas supply/heating device (500) can be reduced. As a result, energy used in the whole system can be reduced.
