Title:
ORGANIC SOLVENT RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/054603
Kind Code:
A2
Abstract:
This organic solvent recovery system includes: a carrier gas circulation path; an adsorption/desorption treatment device which alternately performs the adsorption of organic solvent by the introduction of a gas to be treated and the desorption of organic solvent by the introduction of a carrier gas; a condensing and recovering device which condenses and recovers the organic solvent by cooling the carrier gas discharged from the adsorption/desorption treatment device; and a heating part which is provided on the upstream side of the adsorption/desorption treatment device and heats the low-temperature carrier gas discharged from the condensing and recovering device. The condensing and recovering device has a melting part for temporarily heating and melting the components frozen by cooling. Thus, running costs can be controlled, the capacity for purifying the gas to be treated and the efficiency of recovering the organic solvent can be improved, and the system configuration can be simplified and reduced in size.
