Liquid hydrocarbon treatment method

   
   

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 water and dissolved alkali metal hydroxide; and then (b) separating an upgraded hydrocarbon.

L'invention concerne une méthode pour préparer et améliorer un hydrocarbure contenant des espèces acides telles que des mercaptans, comportant : (a) entrant en contact avec l'hydrocarbure, en l'absence essentielle de l'oxygène, avec une première phase de composition de traitement contenant l'eau, a dissous l'hydroxyde alcalin, sulfonate de phtalocyanine de cobalt, et a dissous des alkylphenylates et ayant au moins deux phases, (i) la première phase contenant l'eau, alkylphenylate alcalin, hydroxyde alcalin dissous, et dissous sulfonated la phtalocyanine de cobalt, et (ii) la deuxième phase contenant l'eau et ont dissous l'hydroxyde alcalin ; et alors (b) séparant un hydrocarbure amélioré.
