The invention pertains to the use of a class of acetylenic surfactants to resolve or break water and oil emulsions. The surfactants are of particular advantage in resolving crude oil emulsions of the type encountered in desalter and similar apparatus designed to extract brines from the crude as they partition to the aqueous phase in the desalter. Also, the surfactants may be used to separate oil from oil sands and similar oil/solids matrices.
L~invention a trait à l~utilisation d~une classe de tensioactifs acétyléniques pour séparer ou rompre des émulsions eau-huile. Ces tensioactifs sont particulièrement avantageux pour séparer des émulsions de pétrole brut telles que celles rencontrées dans les dessaleurs et autres appareils conçus pour extraire les saumures du pétrole brut lorsqu~elles se séparent pour rejoindre la phase aqueuse dans le dessaleur. Les tensioactifs de l~invention peuvent également être utilisés pour séparer les huiles de sables bitumineux et autres matrices huile/solides similaires.
