| 摘要 |
Process for the electrophoretic removal of suspended inorganic solid particles from a residual hydrocarbon oil, said process comprising passing the residual hydrocarbon oil through one or more vessels, each comprising at least one electrode, in which vessel(s) the residual hydrocarbon oil is exposed to a DC electric field having an electric field strength of at least 0.4 kV/cm (1 kV/inch), whereby in total at least 10 % by weight of the initial amount of the selected inorganic solid particles, preferably iron species, are removed by attraction to an electrode. Suitably the treated residual oil is subsequently subjected to hydrodemetallization and hydrodesulphurization.
