Title:
ORGANIC SOLVENT RECOVERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/203780
Kind Code:
A1
Abstract:
An organic solvent recovery system that separates and recovers an organic solvent from a gas to be treated containing the organic solvent, comprising: a circulation route to circulate a carrier gas; an adsorption and desorption device that has an adsorption and desorption element and that alternately performs adsorption of the organic solvent by way of introducing the gas to be treated and desorption of the organic solvent by way of introducing the carrier gas; a condensation and recovery device that is provided in the circulation route on the downstream side of the adsorption and desorption device and that condenses and recovers the organic solvent contained in the carrier gas by cooling the carrier gas discharged from the adsorption and desorption device; and a heating unit that is provided in the circulation route on the upstream side of the adsorption and desorption device and that heats the low-temperature carrier gas discharged from the condensation and recovery device. The condensation and recovery device adjusts the temperature of the carrier gas discharged from the condensation and recovery device so that the vapor pressure of the organic solvent contained in the carrier gas discharged from the condensation and recovery device is less than or equal to a prescribed value.
