Verfahren und Anlage zur Entfernung von in Prozessabwaessern geloesten,wasserdampffluechtigen organischen Loesungsmitteln

摘要

Steam-volatile organic solvents are removed from process waste waters by intimately mixing the process waste waters with steam to form an azeotropic steam mixture, withdrawing the azeotropic steam mixture from the resultant mixture of steam and water, and condensing said azeotropic steam mixture. The major amount of process waste water, thus freed of solvent content, is discharged as general sewage. An apparatus designed to conduct said process is also described.
