    • A recycling process for the demetalization of hydrocarbon oil comprises recycling the following steps: a demetalizing composition for hydrocarbon oil or an aqueous solution thereof is sufficiently mixed with hydrocarbon oil in a desired proportion, and the resultant mixture is subjected to a conventional electrically desalting process to obtain a demetalized hydrocarbon oil and an aqueous desalted solution containing the desalted metal salts; the aqueous desalted solution containing the metal salts is then sufficiently mixed with a precipitating agent in a desired proportion and is subjected to a displacement reaction, and an aqueous solution containing the demetalizing composition is recovered by separating out the residue of the metal salts produced in the displacement reaction, which is poorly soluble or insoluble in water, with a solid-liquid separator; and the recovered aqueous solution containing the demetalizing composition for hydrocarbon oil, which meets the requirements for metal ions in demetalized hydrocarbon oil, is then mixed with hydrocarbon oil in a desired proportion for a next cycle. The present invention has the following advantages such as high efficiency of demetalization, reduction of pollution to the environment and the production cost as well as the metal salt product obtained by treating and collecting the desalted residue of the metal salt.
    • 用于烃油脱金属的再循环方法包括循环以下步骤:将烃油的脱金属组合物或其水溶液与烃油以所需的比例充分混合,并将所得混合物进行常规的电脱盐工艺, 获得脱金属烃油和含有脱盐金属盐的含水脱盐溶液; 然后将含有金属盐的含水脱盐溶液以所需比例与沉淀剂充分混合,并进行置换反应,通过分离出含有脱金属组成的金属盐的残留物,回收含有脱金属组合物的水溶液 与固液分离器相比,其溶解性差或不溶于水; 然后将含有脱金属烃油中的金属离子的要求的含有用于烃油的脱金属组合物的回收水溶液以烃油以所需比例与下一循环混合。 本发明具有如下优点:脱金属的高效率,减少对环境的污染和生产成本以及通过处理和收集金属盐的脱盐残渣得到的金属盐产物。
