CA 2679354

The present invention relates to a process for the control of pitch in an aqueous medium by adding surface-reacted natural calcium carbonate or an aqueous suspension comprising surface-reacted calcium carbonate and having a pH greater than 6.0 measured at 20 °C, to the medium, wherein the surface-reacted calcium carbonate is a reaction product of natural calcium carbonate with carbon dioxide and one or more acids, the use of the surface-reacted natural calcium carbonate for pitch control, as well as to a combination of a surface-reacted natural calcium carbonate and talc for pitch control, and the resulting composites.

La présente invention concerne un processus destiné à agir sur les dépôts de poix dans un milieu aqueux par l'ajout d'un carbonate de calcium naturel ayant réagi en surface ou d'une suspension aqueuse d'un carbonate de calcium ayant réagi en surface et possédant un pH supérieur à 6,0 mesuré à 20°C au milieu en question, ledit carbonate de calcium ayant réagi en surface étant un produit de réaction d'un carbonate de calcium naturel avec de l'oxyde de carbone et d'un ou plusieurs acides, l'utilisation du carbonate de calcium naturel ayant réagi en surface pour agir sur les dépôts de poix, ainsi qu'une combinaison de carbonate de calcium naturel ayant réagi en surface et de talc pour agir sur les dépôts de poix, de même que les composites correspondants.
