Title (EN) LOW-TEMPERATURE STABILIZED AQUEOUS WATER CLARIFIER COMPOSITION AND METHODS OF USE
(FR) COMPOSITION AQUEUSE DE CLARIFICATEUR D'EAU STABILISÉE À BASSE TEMPÉRATURE ET PROCÉDÉS D'UTILISATION
Abstract:
(EN) Disclosed is an aqueous water clarifier composition stable at low temperatures, method to make, and method to use. Said aqueous water clarifier composition comprises: i) a hydrophobically modified alkylene oxide urethane copolymer; ii) a diol; iii) a glycol ether; and iv) optionally a viscosifier. The aqueous water clarifier compositions of the present invention are useful for demulsifying and clarifying oil-water dispersions and emulsions derived from petroleum industry operations.
(FR) L'invention concerne une composition aqueuse de clarificateur d'eau qui est stable à basses températures, un procédé de fabrication et un procédé d'utilisation. Ladite composition aqueuse de clarificateur d'eau comprend : i) un copolymère d'uréthane d'oxyde d'alkylène à modification hydrophobe ; ii) un diol ; iii) un éther de glycol ; et iv) éventuellement un améliorant de viscosité. Selon la présente invention, les compositions aqueuses de clarificateur d'eau sont utiles pour désémulsionner et clarifier des dispersions huile-eau et des émulsions issues d'opérations de l'industrie pétrolière.
