Patent

CA 2449761

The invention relates to a method for treating and upgrading a hydrocarbon containing acidic species such as mercaptans, comprising: (a) contacting the hydrocarbon, in the essential absence of oxygen, with a first phase of a treatment composition containing water, dissolved alkali metal hydroxide, cobalt phthalocyanine sulfonate, and dissolved alkylphenylates and having at least two phases, (i) the first phase containing water, alkali metal alkylphenylate, dissolved alkali metal hydroxide, and dissolved sulfonated cobalt phthalocyanine, and (ii) the second phase containing wate r and dissolved alkali metal hydroxide; and then (b) separating an upgraded hydrocarbon.

L'invention concerne un procédé de traitement et d'amélioration d'un hydrocarbure contenant des espèces acides tels que des mercaptans, consistant (a) à mettre l'hydrocarbure en contact, essentiellement en l'absence d'oxygène, avec une première phase d'une composition de traitement contenant de l'eau, un hydroxyde de métal alcalin dissous, de la phtalocyanine sulfonate de cobalt, ainsi que des alkylphénylates dissous et présentant au moins deux phases, (i) la première phase contenant de l'eau, un alkylphénylate de métal alcalin, un hydroxyde de métal alcalin dissous ainsi que de la phtalocyanine de cobalt sulfonatée dissoute, et (ii) la seconde phase contenant de l'eau ainsi qu'un hydroxyde de métal alcalin dissous; et ensuite (b) à séparer un hydrocarbure amélioré.
