Charles D. Williamson - Houston TX
Stephan J. Allenson - Richmond TX
Robert K. Gabel - Houston TX
Assignee:
Nalco Chemical Company - Naperville IL
International Classification:
E21B 4327
US Classification:

Bimodal Cationics For Water Clarification

View page
US Patent:
46999515, Oct 13, 1987
Filed:
Dec 11, 1985
Appl. No.:
6/807640
Inventors:
Stephan J. Allenson - Richmond TX
Stephen D. Wagner - Bakersfield CA
Assignee:
Nalco Chemical Company - Oak Brook IL
International Classification:
C08L 3302
C08L 3308
C08L 3310
C08L 3326
US Classification:
525194
Abstract:
A polymer admixture comprising a first cationic polymer having a molecular weight between about 2,500-1,000,000 in admixture with a second cationic polymer having a molecular weight between about 1,000,000-50,000,000, wherein said admixture contains a weight ratio of first polymer to second polymer between about 50:1 to 1:50, has greatly improved properties for treating and clarifying waste waters contaminated with oily waste and dispersed solids. The first cationic polymer is preferably a homopolymer, and the second cationic polymer is preferably a copolymer of acrylamide containing the same cationic monomer used to synthesize the first cationic polymer.

Enzymatically Degradable Fluid Loss Additive

View page
US Patent:
50322974, Jul 16, 1991
Filed:
May 19, 1989
Appl. No.:
7/354042
Inventors:
Charles D. Williamson - Sugar Land TX
Stephan J. Allenson - Richmond TX
Robert K. Gabel - Houston TX
David A. Huddleston - Sugar Land TX
Assignee:
Nalco Chemical Company - Naperville IL
International Classification:
C09K 702
US Classification:
252 8551
Abstract:
In treating oil well down hole bores, a method of treating subterranean formations by fracturing by utilization of a fluid loss additive (FLA) comprising starch or a mixture of natural and modified starches plus an enzyme which degrades the alpha linkage of starch and does not the degrade the beta linkage of guar and modified guar where used as a viscosity modifier. Natural/modified starches are utilized in a preferred ratio of 3:7 to 7:3 or 1:9 to 9:1 with optimum at 1:1, and the mix is used in the dry form for application from the surface down the bore hole.

Method For Separating Liquid From Water Using Amine Containing Polymers

View page
US Patent:
50211676, Jun 4, 1991
Filed:
Jul 10, 1989
Appl. No.:
7/377880
Inventors:
Michael L. Braden - Richmond TX

Assignee:
Nalco Chemical Company - Naperville IL
International Classification:
B01D 1704
US Classification:
210708
Abstract:
A method is disclosed for clarifying water comprising dosing the water to be clarified with a copolymer produced by the emulsion polymerization of only hydrophobic monomers where at least one hydrophobic monomer is an amine containing monomer which is hydrophobic when the amine is neutral and hydrophilic when the amine is salified.
