VERFAHREN UND VORRICHTUNG ZUM ABTRENNEN VON WASSER AUS WÄSSRIGEN FLUIDGEMISCHEN

摘要

A method and apparatus permits concentration of a water-miscible organic liquid in a mixture of such liquid and water, with recovery of a desired concentrate of the water-miscible organic liquid and water, and a relatively clean water containing only a very low content of the water-miscible organic liquid which enables disposal of the water in sewage systems, the method and apparatus thus enhancing the ability to satisfy environmental concerns the diluted spent fluid is heated with steam to form a hot frothing mass of liquid and steam which is delivered to a cyclone concentrator (14), the hot frothing mass is maintained at a first pressure and a steam phase including steam bubbles in the hot frothing mass is efficiently separated from and withdrawn from a hot liquid phase which represents a more concentrated mixture. The steam withdrawn from the hot frothing mass is compressed to a second pressure higher than the first pressure and cycled back to provide the steam input.
