The invention relates to a process for treating acidic crudes or fractions thereof to reduce or eliminate their corrosivity by addition of suitable amounts of Group IA or Group IIA oxides, hydroxides, hydroxides hydrates or naphthenate salts to an acidic, corrosive crude, or by reblending a naphthenate salt-containing crude in appropriate ratios with an acidic corrosive crude. The process has the additional benefits of reducing materials handling problems associated with treating acidic crude oils using liquid solvents and in reducing emulsion formation.
L'invention concerne un procédé pour le traitement des pétroles bruts acides ou de leurs fractions en vue de réduire ou d'éliminer la corrosivité de ces produits par adjonction à un brut corrosif acide de quantités appropriées d'oxydes des groupes IA ou IIA, d'hydroxydes, d'hydrates d'hydroxyde ou de sels du type naphténate, ou bien par établissement d'un nouveau mélange selon des dosages appropriés entre un brut contenant du naphténate et un brut corrosif acide. En outre, le procédé présente l'avantage de limiter les difficultés de manipulation des matériaux liées au traitement des pétroles bruts acides suite à l'utilisation de solvants liquides, et aussi de limiter la formation d'émulsions.
