AQUEOUS COMPOSITIONS COMPRISING FUNCTIONALIZED SACCHARIDE POLYMERS FOR DEWATERING OF PARTICULATES

원문 (중국어)

Aqueous compositions comprising an aqueous carrier fluid, a reaction product of a saccharide polymer and a fatty acid or a fatty ester obtained in the aqueous carrier fluid in the presence of a hydroxide base and a neutral surfactant or a reaction product form thereof, a zwitterionic surfactant, and optionally an amine-functionalized saccharide polymer may facilitate dewatering of a plurality of particulates. The reaction product of the saccharide polymer and the fatty acid or the fatty ester, in combination with the neutral surfactant or the reaction product form thereof, and the zwitterionic surfactant may also promote increased aqueous fluid flow through the plurality of particulates. The amine-functionalized saccharide polymer may further increase dewatering of the plurality of particulates and improve clarity of an aqueous filtrate obtained from the plurality of particulates.
