Patent

CA 2414516

Polymer compositions comprised of small, dry polyacrylamide particles may be dispersed into water at industrially useful rates to form aqueous compositions, by separating the particles from each other and bringing them into contact with a moving stream of water in the manner described herein. The resulting aqueous compositions may be used as a treating solution in diverse applications such as flocculants in water treating, papermaking, mining, oil field, and biotechnological separations.

L'invention porte sur des compositions de polymères faites de petites particules sèches de polyacrylamide dispersibles dans l'eau en quantités adaptées à l'industrie, de manière à former des compositions aqueuses en séparant les particules les unes des autres, et en les mettant en contact avec un courant d'eau selon la manière exposée dans la description. Les compositions aqueuses résultantes peuvent servir de solution de traitement dans le cadre de différentes applications tels que des floculants utilisés dans le traitement de l'eau la fabrication de papier, l'extraction minière, l'extraction de pétrole et les séparations biotechnologiques.
