BIODEGRADABLE DEMULSIFIERS

A method of breaking an emulsion may include contacting an emulsion with a demulsifier, where the demulsifier is a dendrimer functionalized with a carboxylic acid derivative and separating the emulsion into two distinct phases. A method of producing crude oil may include extracting a hydrocarbon flu...

Beschreibung
Zusammenfassung:	A method of breaking an emulsion may include contacting an emulsion with a demulsifier, where the demulsifier is a dendrimer functionalized with a carboxylic acid derivative and separating the emulsion into two distinct phases. A method of producing crude oil may include extracting a hydrocarbon fluid from a subterranean formation; adding a demulsifier to the hydrocarbon fluid, where the demulsifier is a dendrimer functionalized with a carboxylic acid derivative; and separating the crude oil emulsion into two distinct phases. La présente invention concerne un procédé de rupture d'une émulsion comprenant la mise en contact d'une émulsion avec un désémulsifiant, le désémulsifiant étant un dendrimère fonctionnalisé avec un dérivé d'acide carboxylique et la séparation de l'émulsion en deux phases distinctes. L'invention concerne également un procédé de production d'huile brute comprenant l'extraction d'un fluide hydrocarboné d'une formation souterraine ; l'ajout d'un désémulsifiant au fluide hydrocarboné, le désémulsifiant étant un dendrimère fonctionnalisé avec un dérivé d'acide carboxylique ; et la séparation de l'émulsion d'huile brute en deux phases distinctes.
