Apparatus For Treating A Flow Of An Aqueous Solution Containing Arsenic

US Patent:
2008015, Jul 3, 2008
Filed:
Oct 31, 2007
Appl. No.:
11/932837
Inventors:
John L. Burba - Parker CO, US
Carl R. Hassler - Gig Harbor WA, US
C. Brock O'Kelley - Las Vegas NV, US
Joseph A. Lupo - Las Vegas NV, US
Joseph R. Pascoe - Las Vegas NV, US
Assignee:
CHEVRON U.S.A. INC. - San Ramon CA
International Classification:
B01D 15/08
B01D 15/38
C02F 1/42
US Classification:
210679, 210175, 210688, 210287
Abstract:
An apparatus for treating an aqueous solution containing arsenic. The apparatus comprises a container that includes a housing, an inlet located at a first end of the housing and an outlet located at a second end opposite the first end. An outer wall extends between the first and second ends and enclosing a fluid flow path between the inlet and the outlet and an arsenic fixing agent is disposed in the fluid flow path. The arsenic fixing agent can include an insoluble rare earth-containing compound, more specifically, a compound comprising one or more of cerium, lanthanum, or praseodymium. The inlet and the outlet are adapted to be closed during transport and storage. The container is adapted to be sealed for long term disposal after exposure to an aqueous solution containing arsenic.

Process For Removing And Sequestering Contaminants From Aqueous Streams

US Patent:
2010018, Jul 29, 2010
Filed:
Dec 7, 2009
Appl. No.:
12/632523
Inventors:
John Leslie Burba - Parker CO, US
Richard Donald Witham - Boulder City NV, US
Edward Bayer McNew - Las Vegas NV, US
Assignee:
Molycorp Minerals, LLC - Greenwood Village CO
International Classification:
C02F 1/58
C02F 1/52
C02F 1/72
C02F 1/28
C02F 1/42
C02F 5/08
C09K 3/00
US Classification:
210665, 210721, 210287, 210282, 2521861
Abstract:
Contaminants, including arsenic, are removed from water and other aqueous feeds preferably by (1) treating the feed with a compound containing a rare earth (e.g., cerium in the +4 oxidation state, preferably cerium dioxide), to oxidize contaminants in the +3 oxidation state to arsenic in the +5 oxidation state and (2) removing the contaminants in the +5 oxidation state from the aqueous phase, normally by contacting the treated feed with a rare earth-containing precipitating agent.

Safe Battery Solvents

US Patent:
2012008, Apr 12, 2012
Filed:
May 13, 2011
Appl. No.:
13/107586
Inventors:
Mason K. Harrup - Idaho Falls ID, US
Thomas A. Luther - Idaho Falls ID, US
John Leslie Burba - Parker CO, US
International Classification:
H01M 10/02
C09K 3/00
C07F 9/6521
US Classification:
429339, 564 13, 252364
Abstract:
An ion transporting solvent for use with batteries can be improved by simultaneously shortening a phosphazene compound's pendent groups, eliminating most or all of the distal ion carriers, and randomizing the solvent molecules so as to intentionally disrupt symmetry to the maximum degree possible. The combination of these strategies dramatically improves battery performance to the point where the performance recorded is comparable to batteries using conventional organic solvents.
