Study on extracting the metals Fe, Ni, V and Ca in residue after atmosphere distillation from the acid citric solution/ iso-propyl alcohol solvent and gasoline
Abstract
The metals Ni, V, Fe, Ca in crude oil usually present porphyrin-type compounds as the metal chelates or organic salt and naphthenate-type compounds as soaps. These metals affect severely to catalyst in RFCC unit. The report searched and evaluated the effects of extraction to the metals Fe, Ni, V and Ca removing from atmosphere residue at CDU of Dung Quat refinery by chelate citric acid/iso-propyl alcohol in solvent directly distillated gasoline. The chelate is not only friendly to environment and but also easily solve in water and soluble ability in oil. The chelate has pH = 6.5, with pH it is without corrosion to the equipment and can apply in the industry. The results from ICP show that the removal Fe, Ni, V and Ca being highly present with 100%, 86.5%, 99%, 69.7% respectively are higher than the efficiency of extraction in water solvent to 31.7%, 35.9%, 52.4%, 50.7% respectively.
