Title: Method and apparatus for removing water from aqueous fluid mixture
Inventor: GAMMON PETER HENRY FIRTH
IPC: B01D1/28
Filed: 1997-12-05
Abstract: 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 method has particular application to the recovery of a reusable glycol/water mixture from diluted spent aircraft deicer fluid (ADF).      The diluted spent ADF is heated in a plate heat exchanger with steam to form a hot frothing mass of liquid and steam which is delivered to a cyclone concentrator, the hot frothing mass in the plate heat exchanger and the cyclone concentrator are 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a first pressure and a steam phase including steam bubbles in the hot frothing mass is efficiently separated from and withdrawn from a hot liquid phase which represents a more concentrated glycol/water mixture. The steam withdrawn from the hot frothing mass is compressed to a second pressure higher than the first pressure and cycled back to provide the steam input of the plate heat exchanger.      After start-up the operation proceeds, with maintenance of the pressure differential, exploiting the heat of the compressed steam with no requirement for external heating. The method and apparatus may be applied to other aqueous fluid mixtures.
