US Patent:

7238288, Jul 3, 2007

Filed:

Aug 13, 2004

Appl. No.:

10/918157

Inventors:

Huizhen Gao - Carlsbad NM, US
Yifeng Wang - Albuquerque NM, US
Charles R. Bryan - Albuquerque NM, US

Assignee:

Sandia Corporation - Albuquerque NM

International Classification:

C02F 1/28
C02F 1/62

US Classification:

210688, 210912

Abstract:

A method for absorbing an ion from a fluid by using dispersing an organic acid into an anion surfactant solution, mixing in a divalent-metal containing compound and a trivalent-metal containing compound and calcining the resulting solid layered double hydroxide product to form an absorbent material and then contacting the absorbent material with an aqueous solution of cations or anions to be absorbed.

International Classification:

B01D 59/16

US Classification:

96221, 95 34, 95289

Abstract:

A process and apparatus for separating a gas mixture comprising providing a slot in a gas separation channel (conceptualized as a laterally elongated Clusius-Dickel column), having a length through which a net cross-flow of the gas mixture may be established; applying a higher temperature to one side of the channel and a lower temperature on an opposite side of the channel thereby causing thermal-diffusion and buoyant-convection flow to occur in the slot; and establishing a net cross-flow of a gas mixture comprising at least one higher density gas component and at least one lower density gas component along the length of the slot, wherein the cross-flow causes, in combination with the convection flow, a spiraling flow in the slot; and wherein the spiral flow causes an increasing amount of separation of the higher density gas from the lower density gas along the length of the channel. The process may use one or more slots and/or channels.

International Classification:

E21B 41/00

Abstract:

A method for geo-sequestration of a carbon dioxide includes selection of a target water-laden geological formation with low-permeability interbeds, providing an injection well into the formation and injecting supercritical carbon dioxide (SC—CO) and water or bine into the injection well under conditions of temperature, pressure and density selected to cause the fluid to enter the formation and splinter and/or form immobilized ganglia within the formation.
