A PROCESS FOR BREAKING EMULSIONS OR PREVENTING EMULSION FORMATION

Process for contacting a mixture of water and oil with a hyperbranched polyester. In the process the formation of an emulsion is prevented. If before the contacting an emulsion was formed, the emulsion is broken. The process is very suitable to be applied during the winning or transportation of crud...

Zusammenfassung:	Process for contacting a mixture of water and oil with a hyperbranched polyester. In the process the formation of an emulsion is prevented. If before the contacting an emulsion was formed, the emulsion is broken. The process is very suitable to be applied during the winning or transportation of crude oil. L'invention concerne un procédé de mise en contact d'un mélange d'eau et d'huile avec un polyester hyperramifié. Lors de ce procédé, la formation d'une émulsion est empêchée. Au cas où une émulsion se forme avant la mise en contact, cette émulsion est rompue. Ce procédé est bien adapté à une mise en oevre durant l'extraction ou le transport d'huile brute.
