CA 2695180

A method of facilitating separation of hydrocarbon from a mixture comprising 5 hydrocarbons and water is dis-closed. The mixture is exposed to a composition comprising at least certain polymeric surfactants such that at least a portion of the hydrocarbons forms a separate layer from the remaining portion of the mixture. The disclosure further provides a use of certain polymeric surfactants to at least partially separate hydrocarbon from a mixture comprising hydrocarbons and water such that at least a portion of the 10 hydrocarbons forms a separate layer from the remaining portion of the mixture. The disclosure further provides a method of removing a sludge comprising a mixture of petroleum and water from a surface, the method comprising treating the sludge with an amount of a composition comprising certain polymeric surfactants effective to remove the sludge from the surface.

L'invention concerne un procédé permettant de faciliter la séparation d'hydrocarbures d'un mélange comprenant 5 hydrocarbures et de l'eau. Le mélange est exposé à une composition comprenant au moins certains agents tensioactifs polymères de telle sorte qu'au moins une partie des hydrocarbures forme une couche distincte de la partie restante du mélange. L'invention concerne en outre l'utilisation de certains agents tensioactifs polymères pour séparer au moins partiellement un hydrocarbure d'un mélange comprenant des hydrocarbures et de l'eau de telle sorte qu'au moins une partie de 10 hydrocarbures forme une couche distincte de la partie restante du mélange. L'invention concerne en outre un procédé permettant d'enlever d'une surface une boue comprenant un mélange de pétrole et d'eau, le procédé comprenant le traitement de la boue avec une quantité d'une composition comprenant certains agents tensioactifs polymères efficaces pour enlever la boue de la surface.
