Title: (DE) NEUE COPOLYMERE ZUR VERWENDUNG ALS ÖLFELD-DEMULGATOREN
(EN) NOVEL COPOLYMERS FOR USE AS OILFIELD DEMULSIFIERS
(FR) NOUVEAUX COPOLYMÈRES DESTINÉS À ÊTRE UTILISÉS COMME DÉSÉMULSIFIANTS DANS DES CHAMPS PÉTROLIFÈRES
Abstract:
(EN) Lactone/alkylene oxide polymers are useful as demulsifiers to break emulsions, e.g. water-in-oil and oil-in-water emulsions, particularly oilfield emulsions. These polymers are random or block polymer made from addition reactions of a hydroxyl- and/or amine-containing base compound with at least one lactone monomer and at least one alkylene oxide monomer.
(FR) Les polymères de lactone/oxyde d'alkylène selon l'invention sont des désémulsifiants utiles pour casser les émulsions, par exemple, les émulsions eau dans l'huile et huile dans l'eau, en particulier, les émulsions que l'on trouve dans des champs pétrolifères. Ces polymères sont des polymères statistiques ou séquencés obtenus par des réactions d'addition d'un composé de base contenant un hydroxyle et/ou une amine avec au moins un monomère de lactone et au moins un monomère d'oxyde d'alkylène.
