1,165,128. Gravity separation of immiscible liquids. ESSO RESEARCH & ENG. CO. 17 Jan., 1968 [7 Feb., 1967], No. 2565/68. Heading B1D. A plurality of gravity separation stages (e.g. 15, 26) are spaced above one another within the inner jacket 300 of a separator 1 for immiscible liquids such as oils and water; each such stage has (i) a funnel with its smaller aperture 20, 118 directed downwards, and (ii) a peripheral diffuser comprising a set of baffle plates 200 for conducting liquid inwardly from the space 302 between housing 2 and Jacket 300; and the space 302 extends upwardly into a chamber having an outlet for separated liquid. As described, oil-and-water mix flows in at 127 and down to space 302 via concentric sets of plates 326 which collect oils by surface tension. Collected oils flow over weirs 121, 126 into chamber 42 and out at 337. The partly purified mix then flows into stage 15 via diffusing plates 200, which again cause surface tension separation, oils flowing up wall 2 into chamber 42 whereas water enters stage 22, where a similar separation operation occurs. Water flows over edge 118a and out via sleeve 313 and pipe 338. For use on board ship, an anti-roll skirt (309) (Fig. 1, not shown) is secured to the bottom 301 of jacket 300, defining an oil-collecting stage 310 there. Additional anti-roll devices include baffles 343, Fig. 2. Valve-controlled apertures (21 1 ), (11 1 ) (Fig. 1) allow removal of sediment via outlet (3a). Openings 316, 318, 321 are for ventilation and access purposes. |
