Appl. No.:

09/385321

Inventors:

Deon Eugene Campbell - Vancouver WA
Dustin Kimbel James - Sugar Land TX
Jereme Francis - Vancouver WA
Thomas Stocker - San Diego CA

Assignee:

Koch Microelectronic Service Co., Inc. - Houston TX

International Classification:

B01D 6100

US Classification:

210652, 210639, 210651, 210739, 2102572, 134 10

Abstract:

A process for treating waste water containing hydrofluoric acid, mixed acid etchant waste, dissolved silica, and solid particles is provided. This process involves adjusting the pH of the waste water to about 7 or above, filtering the waste water to remove solid particles, adding an anti-scalant to the waste water, and feeding the waste water through a reverse osmosis membrane. The reverse osmosis membrane separates the waste water into a permeate stream, which is the product, and a reject stream. Another aspect of the present invention is a system for performing this process.

Abstract:

A process for treating aqueous waste comprising a copper plating waste stream, a copper rinse stream containing organic carbon and solid particles, and a copper chemical mechanical planarization stream (CMP) containing solid particles is provided. This process includes electrowinning the copper plating waste stream to remove copper and create a blow down stream, filtering the rinse stream to remove solid particles, adding the blow down stream to the CMP stream, treating the blow down stream and the CMP stream with a flocculant or coagulant to form larger solid particles, removing the larger solid particles from the CMP stream and separating the resulting stream into a liquid containing copper, a concentrated regenerant, and a dilute regenerant, adding the concentrated regenerant to the waste stream before the electrowinning step, adding the dilute regenerant to the rinse stream before filtering to remove solid particles, and adding the liquid containing copper to the CMP stream during the treating step. The present invention further includes a system for treating aqueous waste that follows the above-described process.

Assignee:

EnviroFuels LLC - Houston TX

International Classification:

C07F 9/02

US Classification:

554 78

Abstract:

The present invention provides a continuous process for producing an oil based phosphate containing product. The continuous process includes mixing water with at least one base and an orthophosphoric acid to produce a liquid phosphate salt containing solution. This solution is then dried, granulated, and mixed with a base stock hydrocarbon to form the oil based phosphate containing product.

US Classification:

210638

Abstract:

A process for treating waste water containing copper and other particles from a chemical mechanical planarization (CMP) process is provided. This process includes adjusting the pH of the waste water to between about 3 and 4, adding a coagulant or flocculating polymer to the waste water to generate larger particles, filtering the waste water through a filtration unit to produce a permeate and solids, feeding the permeate through a carbon bed to remove total organic carbon, and feeding the carbon bed treated permeate through an ion exchange column to remove copper from the permeate. This process may further involve washing sludge collected in a concentration tank with the treated stream exiting the ion exchange column. Still further, another aspect of the present invention is a system for performing the process described above.

International Classification:

C08K 501
B41M 512

US Classification:

106311

Abstract:

A carbonless paper solvent is provided comprising diisopropylmethylnaphthalene, generally in an amount of from 20% to 100% of the total weight of the solvent. The solvent is combined with a chromogenic substance and is encapsuled into microcapsules. The microcapsules are applied to a sheet of material and a color developing substance is then applied to another sheet to form a carbonless marking system. When the microcapsules are ruptured, the solubilized chromogenic substance contacts and reacts with the developer to form an image. In a method of the invention, a by-product fraction consisting of components with a boiling point range of 200. degree. to 400. degree. C. are contacted with propylene under conditions sufficient to form an alkylation product comprising diisopropylmethylnaphthalene.
