Method and apparatus for separating organic solvent in gas

Abstract

Abstract PURPOSE:To efficiently condense and separate org. solvent gas by directly bringing cooling gas into contact with gas containing an org. solvent to condense the org. solvent under cooling and separating the condensed org. solvent from the gas. CONSTITUTION:The org. solvent gas generated in a generation tank 5 is introduced into a treatment tank 1 along with air from introducing piping 8 by the suction fan 9 provided to lead-out piping 10 while the liquefied cooling medium in a cooling medium storage tank 12 is injected and supplied to the treatment tank 1 from cooling medium supply piping 13. Whereupon, the liquefied cooling medium is instantaneously reduced in its pressure to be gasified and becomes cooling medium gas having temp. markedly lower than the condensing temp. of the org. solvent to cool the air containing the gas of the org. solvent in the treatment tank 1 to temp. lower than the condensing temp. of the org. solvent. Therefore, the org. solvent gas and steam in the treatment tank 1 are condensed to respectively become the org. solvent liquid and water and stored in a storage part 15 to be appropriately led out to a moisture separator 17 from a discharge port 16.
