Title:
METHOD FOR RECOVERING SOLVENT FROM WASTE GAS
Document Type and Number:
Japanese Patent JPH05200247
Kind Code:
A
Abstract:
PURPOSE: To continuously recover the solvent included in waste water without alternate operations.
CONSTITUTION: A solvent is recovered from the waste gases by condensation, freezing out and/or desublimation on shaped objects 4 in a shaped-object reservoir 1 cooled by a refrigerator. The shaped objects 4 pass the shaped-object reservoir 1 in counter current to the waste gases and return again to the reservoir 1 through a transporting device 8 arranged outside the shaped-object reservoir 1 and a closed transporting circuit including a heat exchanger 10. The shaped objects 4 may be cooled by the liquid nitrogen introduced in the heat exchanger 10.
