1,203,094. Separating water and petroleum products. HECTRONIC A.G. 21 Sept., 1967 [26 Sept., 1966], No. 43090/67. Heading B1D. A coalescer element (e.g. 16a, Fig. 1) comprising a bed of particles more readily wettable by petroleum products than by water divides a container 10 into: an inlet compartment 20 having an inlet 21; and an outlet chamber 22 having a device (e.g. a funnel 23a) for collecting petroleum products rising buoyantly from the coalescer element 16a connected to a petroleum products outlet 26a, there being on the same side of the coalescer a water outlet 27a. As described, Fig. 1, there are two or more coalescer elements 16a, 16b made of p.t.f.e. turnings and arranged in series. Petroleums are discharged at 26a, 26b, at a level higher than water weir level 27. Fig. 2 (not shown) illustrates a modification: a first collecting funnel (43) receives those larger petroleums droplets which rise immediately; each coalescer element (36a - c) is mounted annularly on the collecting funnel of the preceding filter stage; and the petroleums discharge pipes (45-45c) are arranged concentrically. In Fig. 4, flow is indicated by the arrows, 77a - c being the coalescer elements: petroleums rise up tubes 82-84 and water at 91, water also being delivered via pump 86 and tubes 87, 88 to seal the spaces above funnels 78, 79. In Fig. 5 (not shown) the coalescer element (101) are annular; their centres are stopped by disc plugs (102) above which lie the apertures (104) in the centres of collector devices (103), petroleums being drawn off through tubes (105) in the sides of the container (100). |
