Patent

CA 2597082

Materials and a method are provided whereby polymers with least 0.5 mole % of the pendant group or end group containing - Si (OR")3 (where R" 'is H, an alkyl group, Na, K, or NH4) are used to control aluminosilicate scaling in an industrial process having an alkaline process stream such as a pulping mill process stream. When materials of the present invention are added to the alkaline process stream, they reduce and even completely prevent formation of aluminosilicate scale on equipment surfaces such as evaporator walls and heating surfaces . The present materials are effective at treatment concentrations that make them economically practical.

L~invention concerne des matériaux et un procédé selon lesquels des polymères ayant au moins 0,5 mol% du groupe pendant ou d~un groupe terminal contenant - Si (OR")3 (où R" est H, un groupe alkyle, Na, K ou NH4) sont utilisés pour limiter la formation de dépôts d~aluminosilicate au cours d~un procédé industriel impliquant un flux alcalin, par exemple un flux d~une usine de pâte à papier. Lorsque des matériaux de la présente invention sont ajoutés dans le flux alcalin, ils réduisent, voire même empêchent totalement la formation de dépôts d~aluminosilicate sur les surfaces des équipements, telles que les parois d'évaporateurs et les surfaces chauffantes. Les matériaux de la présente invention sont efficaces à des concentrations de traitement qui les rendent pratiques sur le plan économique.
