US Patent:

6420185, Jul 16, 2002

Filed:

Sep 28, 1999

Appl. No.:

09/408188

Inventors:

Gregory E. Carr - Portland OR

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G01N 134

US Classification:

436177, 73 6141, 73 6142, 73 6159, 7386323, 210650, 210652, 210900, 422101, 436178

Abstract:

An apparatus and methods of utilizing a semi-permeable membrane to concentrate contaminants in a portion of an Ultra Pure Water stream to levels which are detectable by an on-line analyzer. This allows the use of analyzers that would not be able to accurately detect contaminant concentrations in the Ultra Pure Water stream. Thus, by knowing the concentration factor and the level of contaminants in the concentrated stream indicated by the analyzer the real level of contamination can be back calculated.

Appl. No.:

11/392119

Inventors:

Gregory Carr - Portland OR, US

International Classification:

G01N 33/00
G01N 33/48

US Classification:

436135000, 422068100

Abstract:

The presence and amount of hydrogen peroxide in a liquid can be determined by breaking down hydrogen peroxide into water and oxygen gas. By monitoring a base level of dissolved oxygen and comparing that to the amount of oxygen after breaking down the hydrogen peroxide, one can determine the amount of hydrogen peroxide in the liquid flow.

US Classification:

202158

Abstract:

A compact solvent reprocessing system for use in a limited physical area. Solvents to be reprocessed is contacted by deionized water in a water wash column and delivered to a distillation column where waste solvent is separated from materials that boil at a higher temperature than the waste solvent. Distilled solvent is delivered to a drying column and final filters for removal of any other foreign materials. The modular solvent reprocessing system to reclaim/recycle high purity solvents on-site at a manufacturing facility. A system includes a pumpless pressurized tank solvent transfer units, storage tanks, liquid-liquid extraction column, distillation columns, submicron filtration units, and water and acid adsorption columns arranged as necessary to produce ultra-high purity solvents from waste solvent streams. The systems are packaged in modular assemblies with secondary containment to meet U. S. EPA requirements.
