Filed:

Mar 29, 2001

Appl. No.:

09/823026

Inventors:

Ryan D. McMurtrey - Idaho Falls ID
Daniel M. Ginosar - Idaho Falls ID
Kenneth S. Moor - Idaho Falls ID

Donna L. Barker - Idaho Falls ID

Assignee:

Bechtel BWXT Idaho, LLC - Idaho Falls ID

International Classification:

B01D 1100

US Classification:

210634, 210639, 210747, 210774, 210805, 210170, 210177, 210194, 210511, 166267

Abstract:

A method and system for extraction of chemicals from an groundwater remediation aqueous effluent are provided. The extraction method utilizes a critical fluid for separation and recovery of chemicals employed in remediating groundwater contaminated with hazardous organic substances, and is particularly suited for separation and recovery of organic contaminants and process chemicals used in surfactant-based remediation technologies. The extraction method separates and recovers high-value chemicals from the remediation effluent and minimizes the volume of generated hazardous waste. The recovered chemicals can be recycled to the remediation process or stored for later use.

International Classification:

G05D 7/06
F16K 31/54

US Classification:

137 14, 137331, 137486, 1374875, 251215, 251250

Abstract:

A system, apparatus and method of controlling the flow of a fluid are provided. In accordance with one embodiment of the present invention, a flow control device includes a valve having a flow path defined therethrough and a valve seat in communication with the flow path with a valve stem disposed in the valve seat. The valve stem and valve seat are cooperatively configured to cause mutual relative linear displacement thereof in response to rotation of the valve stem. A gear member is coupled with the rotary stem and a linear positioning member includes a portion which complementarily engages the gear member. Upon displacement of the linear positioning member along a first axis, the gear member and rotary valve stem are rotated about a second axis and the valve stem and valve seat are mutually linearly displaced to alter the flow of fluid through the valve.

US Classification:

210/749000

Abstract:

An apparatus and method for extraction of chemicals from an aquifer remediation aqueous effluent are provided. The extraction method utilizes a critical fluid for separation and recovery of chemicals employed in remediating aquifers contaminated with hazardous organic substances, and is particularly suited for separation and recovery of organic contaminants and process chemicals used in surfactant-based remediation technologies. The extraction method separates and recovers high-value chemicals from the remediation effluent and minimizes the volume of generated hazardous waste. The recovered chemicals can be recycled to the remediation process or stored for later use.
