Waste Acid Recovery
View pageUS Patent:
61593826, Dec 12, 2000
Filed:
Oct 7, 1998
Appl. No.:
9/167563
Inventors:
Lawrence D. Conant - West Bridgewater MA
Arie Keus - Lynn MA
Arie Keus - Lynn MA
Assignee:
Waterworks International Inc. - Woburn MA
International Classification:
C01B 1790
US Classification:
210712
Abstract:
A process for purifying a sulfuric acid solution such as by cooling a sulfuric acid solution to at or near its freezing point to form a slurry of a solid phase and a liquid phase. The slurry has an acid-rich region and an acid-poor region. The acid-rich region is separated from the acid-poor region on the basis of density.
Freeze Crystrallization For The Removal Of Water From A Solution Of Dissolved Solids
View pageUS Patent:
55378323, Jul 23, 1996
Filed:
Nov 2, 1995
Appl. No.:
8/538954
Inventors:
Arie Keus - Lynn MA
Assignee:
Waterworks International, Inc. - Maynard MA
International Classification:
B01D 904
US Classification:
62544
Abstract:
A freeze crystallization concentration system is disclosed for separating a liquid feed stream into a more purified liquid and a concentrate in which only a single pass through a freeze-crystallizer and ice separator is required. The crystallizer, which converts the initial feed stream into a slurry of ice and concentrate, includes a scraped surface heat exchanger that produces, pumps and removes an ice slurry and uses a secondary cooling system to ensure that the crystallizer will operate in any required position and is not sensitive to motion. The separator includes a rotating drum which separates the ice crystals from the surrounding concentrate by the use of centrifugal force and without the use of screens or filters. An auger, rotating at a different speed than the drum, may be located at the center of the drum for removing the ice crystals. A second drum, attached to the first drum, removes the concentrate with a stationary pivot tube under pressure created by the centrifugal force, without the concentrate being exposed to air.
