A DEMETALIZING AGENT FOR HYDROCARBON OIL AND ITS PREPARATION AND USE

摘要

A demetalizing agent for hydrocarbon oil and its preparation and use: the demetalizing agent for hydrocarbon oil contains a demetalizing agent, a demulsifier and a supported metal-removing agent, its aqueous solution further includes water; the demetalizing agent for hydrocarbon oil. is obtained by mixing the components sufficiently. The use method comprises the following steps: Mix the demetalizing agent for hydrocarbon oil or its aqueous solution with hydrocarbon oil sufficiently in proportion needed, then the demetaled hydrocarbon oil is obtained after traditional desalting process; The process in this invention is simple and easy to performed, it can remove metal ions in the hydrocarbon oil, such as Ca, Mg, Fe, V, Ni with traditional desalting process, its separation effect is good, the interface between the oil and water is clear, and the separated waste water has a low oil content; The demetalizing agent for hydrocarbon oil has low solidifying point which is very suitable in winter, it is not only suitable for crude oil with high, middle or low content of Ca, Mg and other metal ions, but also for distillates, atmosphere or vacuum residue, all kind of feed oil, refined oil, renewed oil or dirty oil in petrochemical production.
