Title (EN) METHOD OF REGENERATION OF A HYDROCARBON BASED LIQUID THAT CONTAINS TITANIUM AND/OR CHLORINE COMPOUNDS
(FR) PROCEDE DE REGENERATION D'UN LIQUIDE A BASE D'HYDROCARBURES CONTENANT DES COMPOSES DE TITANE ET/OU DE CHLORE
Abstract:
(EN) The invention is concerned with a method of regeneration of a hydrocarbon based washing liquid that contains titanium and chlorine compounds. The titanium and chlorine compounds in the hydrocarbon based solution is removed so that the hydrocarbon solution is brought into contact with a silica that contains hydroxylic groups after which the silica is regenerated by means of water, for recovery.
(FR) L'invention se rapporte à un procédé de régénération d'un liquidede lavage à base d'hydrocarbures contenant des composés de titane et de chlore. On supprime les composés de titane et de chlore de la solution à base d'hydrocarbures pour mettre celle-ci en contact avec une silice contenant des groupes hydroxyles, après quoi on régénère la silice en utilisant de l'eau pour la récupérer ensuite.
