<p><P>PROBLEM TO BE SOLVED: To provide an organic solvent-treating apparatus regenerating a recovered solvent in an extremely high level by effectively removing an acid component in a recovered solvent even when an organic solvent is recovered from the organic solvent-containing gas and the acid component is included in the recovered solvent. <P>SOLUTION: The organic solvent-treating apparatus are characterized in that an acid component in a recovered solvent is eliminated by recovering an organic solvent from an organic solvent-containing gas and bringing the recovered solvent into contact with a water-soluble reducing agent. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
