Polymers And Use Thereof As Scale Inhibitors

US Patent:
6440327, Aug 27, 2002
Filed:
Jan 31, 2001
Appl. No.:
09/774413
Inventors:
Sergey M. Shevchenko - Lisle IL
Prasad Y. Duggirala - Naperville IL
Assignee:
Ondeo Nalco Company - Naperville IL
International Classification:
C02F 502
US Classification:
252175, 562409, 562410, 562411, 562412, 562419
Abstract:
Compositions and methods for inhibiting scale are provided. Pursuant to the present invention, a composition for inhibiting scale is provided that includes a carbohydrate polymer having both nitrogen-containing groups and carboxyl groups. The nitrogen-containing groups include amino groups, amido groups and mixtures thereof. The present invention has been found useful for inhibiting scale in industrial waters, such as, pulp bleach plant process waters which contain calcium oxalate and barium sulfate scale.

Abstract:
Described herein are methods of reducing the deposition of organic contaminants, such as pitch and stickies, in papermaking processes.

Method And Apparatus For Measuring Scaling Capacity Of Calcium Oxalate Solutions Using An Electrochemically Controlled Ph Change In The Solution Proximate To A Piezoelectric Microbalance

US Patent:
6375829, Apr 23, 2002
Filed:
Mar 7, 2000
Appl. No.:
09/519688
Inventors:
Sergey M. Shevchenko - Lisle IL
Dmitri L. Kouznetsov - Naperville IL
Prasad Y. Duggirala - Naperville IL
Assignee:
Nalco Chemical Company - Naperville IL
International Classification:
G01N 2742
US Classification:
2057935, 205794, 204434, 73 6162, 73 6175
Abstract:
This invention is directed to a method and apparatus for measuring the rate of calcium oxalate scale formation in a continuously flowing solution having a pH of from about 2 to about 3 comprising measuring the rate of deposition of calcium oxalate scale from the solution on to a quartz crystal microbalance having a top side comprising a working electrode in contact with the solution and a second, bottom side isolated from the solution, wherein the pH of the solution proximate to the microbalance is measured using a pH measuring module and is controlled electrochemically at from about 3. 5 to about 9 and wherein the working electrode is coated with or made of a conductive material on which the intensive evolution of hydrogen gas proceeds at potentials more negative than those necessary to achieve a pH of 3. 5-9 proximate to the microbalance.
