<p>FILTERING PROCESS A process for separating finely divided, electrically conductive materials from hot liquid hydrocarbon feed stock for a fixed bed catalytic process such as hydrodesulfurization of gas oils or heavier petroleum fractions or hydrocracking. The feed stock is made to flow longitudinally between electrodes and through a bed of spherical glass particles. A voltage gradient of 5 to 25 kv per inch is applied to the electrodes. Periodically the filter is cleaned by backflushing with filtered product. The backflush liquid and entrained solids are delivered into a fluidized unit to dispose of the solids removed in the backflush liquid. In a specific embodiment, the backflush liquid and entrained solids are delivered into a fluidized catalytic cracking unit.</p> |
