US Patent:

20060272500, Dec 7, 2006

Filed:

Jun 7, 2005

Appl. No.:

11/147583

Inventors:

Arturo Keller - Santa Barbara CA, US
Michael Joy - Newbury Park CA, US
Lawrence Neill - Camarillo CA, US
Mark Galliher - Thousand Oaks CA, US

International Classification:

B01D 53/22

US Classification:

095046000

Abstract:

A method of removing volatile and semi-volatile compounds from an aqueous stream is provided which may include injecting a scale reducing gas having a primarily inert gas containing carbon dioxide into the aqueous stream; flowing the stream past a first surface of a wall of a microporous, hydrophobic gas separation membrane that is substantially impermeable to water but is permeable to vapors from the volatile and semi-volatile compounds; applying a vacuum to a second surface of the wall of the membrane to draw the vapors of the compounds through the wall of the membrane; flowing a sweep gas from the first surface of the wall to the second surface of the wall to facilitate movement of the vapors through the wall of the membrane, wherein the sweep gas is a primarily inert gas containing carbon dioxide; and flowing the drawn vapors through an oxidation device to oxidize the drawn vapors.

International Classification:

B01J 802

US Classification:

422189

Abstract:

Combustible hydrocarbon gas from a contaminated zone of soil and/or water is abated by removing hydrocarbon gas from the zone, combusting a first portion of the hydrocarbon gas in an internal combustion engine to develop power and to produce hot exhaust gas, delivering a second portion of the hydrocarbon gas and the hot exhaust gas to a catalytic unit, passing the hot gas exiting the catalytic unit in countercurrent heat exchange relation to the second portion of the hydrocarbon gas before venting said exit gas and utilizing the power from said engine to remove hydrocarbon gas and contaminated water from the zone and to pump the gases throughout the system.
