    摘要： It has been discovered that metals and/or amines can be removed or transferred from a hydrocarbon phase to a water phase in an emulsion breaking process by using a composition that contains water-soluble hydroxyacids. Suitable water-soluble hydroxyacids include, but are not necessarily limited to glycolic acid, gluconic acid, C 2 -C 4 alpha-hydroxy acids, poly-hydroxy carboxylic acids, thioglycolic acid, chloroacetic acid, polymeric forms of the above hydroxyacids, poly-glycolic esters, glycolate ethers, and ammonium salt and alkali metal salts of the hydroxyacids, and mixtures thereof. The composition may also include at least one mineral acid to reduce the pH of the desalter wash water. A solvent may be optionally included in the composition. The invention permits transfer of metals and/or amines into the aqueous phase with little or no hydrocarbon phase undercarry into the aqueous phase. The composition is particularly useful in treating crude oil emulsions, and in removing calcium and other metals therefrom.

    摘要： The invention relates to field of processing hydrocarbon feedstock including crude oil, wherein metals such as calcium are removed. In the face of the rising prices of crude oil, refiners are forced to process opportunity crudes such as DOBA, which pose many problems including fouling of equipment due to certain metallic salts, such as calcium napthenate. Calcium, which cannot be removed from crude oil during normal desalting process, poses very serious problems. The invention provides method for removal of calcium, wherein crude oil is mixed, with effective metal removing amount of aqueous extraction solution of an additive comprising a chemical compound selected from a group consisiting of metallic acid, maleic anhydride or fumaric acid or salts or derivatives thereof, enabling separation of hydrocarboneous phase and aqueous phase containing metal ions, in crude desalter. Only hydrocarboneous phase devoid of calcium is processed further, thereby preventing fouling of equipment.
