Abstract
897,789. Filters combined with gravityseparation apparatus. DOUGLAS, E. Nov. 23, 1960 [Aug. 26, 1959], No. 29145/59. Class 46. A mixture of oil and water is pumped (10) from a ballast or like tank 13 to a combined filter and settler 1 at 5. The mixture passes downwards through an array of concentric flow-stabilizing cylinders 9 and through a pebble-bed filter 3, upon which oil is deposited, the water being discharged at 19; the valves on oil discharge pipe 6 and air vent 7, and valves 16, 18 and 20 are all closed. To clean the filter bed, valves 14 and 19 are closed and valve 16 and the valve on pipe 6 are opened. Purging water is pumped from a branch 15 through valve 16, and oil floating in the apparatus 1 is discharged at 6. Next, valve 16 and the valve on pipe 6 are closed, and air vent 7 and a waste valve 18 are opened, the latter being closed when the water has drained to within 2 inches of the top of bed 3. With valves 18 and 19 closed valve 20 is opened and steam (and, optionally, air) is admitted from an inlet 22, followed by water from an inlet 21, the rate of flow being sufficient to fluidise the bed and the temperature of the bed being raised sufficiently to release oil adhering to the pebbles, the thus released oil being discharged at 6. Air and uncondensed steam escape at 7. Finally all air is ejected by filling the apparatus with purging water. On closing valve 20 and vent 7 and opening valve 19 the apparatus is ready to receive the next charge from tank 13. A steam heating coil 8 is located in the top of the apparatus.
