Patents by Inventor William A. Shaw

William A. Shaw has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process of scrubbing volatiles from evaporator water vapor
    Patent number: 8778037
    Abstract: A process is provided where a waste stream is directed to an evaporator that produces a vapor having volatile compounds. The vapor including the volatile compounds is directed through a vapor scrubber that contacts the volatile compounds with a scratching solution. The scrubbing solution reacts with the gaseous volatile compounds in the vapor such that the volatile compounds pass from a vapor state into the scrubbing solution and form volatile compounds in the liquid scrubbing solution. The scrubbing solution is collected and recycled.
    Type: Grant

    Date of Patent: July 15, 2014
    Assignee: Veolia Water Solutions & Technologies North America, Inc.

  • Gasification process
    Patent number: 8491680
    Abstract: A gasifier waste stream from a gasification process is directed to a solids separator. A portion of the suspended solids in the waste stream is removed in the solids separator, producing slag and fly ash and a grey water effluent. The grey water effluent is directed to one or more ceramic membranes which remove at least portions of the remaining suspended solids in the grey water. Permeate from the ceramic membrane is directed to an evaporator located downstream from the ceramic membrane for further concentration. Placing the ceramic membrane upstream from the evaporator reduces fouling and plugging in the evaporator that would otherwise occur due to the suspended solids in the grey water.
