Abstract: 1,175,290. Separating liquids. ESSO RESEARCH & ENG. CO. 30 Oct., 1967 [22 Nov., 1966], No. 49132/67. Heading B1D. A suspension of droplets of oil is separated from water by (i) passing the mixture through a coalescing medium 24 to produce larger droplets and (ii) thereafter passing it through a plurality of horizontal ducts 30 having oil retaining lips 40 the surfaces of the ducts produce a secondary coalescing effect while the denser liquid settles by gravity as the mixture travels along the ducts. The ducts act to prevent turbulent flow. As described, the mixture is delivered from a preliminary conventional gravity separator 10 to a chamber 16 and thence through a coalescer cartridge 20, which comprises a multifilament-strand mesh web 24 rolled into a spiral (the mixture travelling along its longitudinal axis), followed by a bubble-rupturing screen 26 comprising needles (60), Fig. 8 (not shown). The medium 24 and at least one wall of each duct 30 is formed from a lipophilic material such as polypropylene. The oil layer in each duct is arrested terminally by an overhanging lip 40; oil flows out at 46, water at 48, 50. It is stated that a unit having a capacity of 1200 gallons p.m. and a pressure drop of less than 2 p.s.i. has been constructed within dimensions of 4 x 10 feet.

Abstract: The light phase in a liquid-liquid extraction tower having vertically spaced cross flow trays and seal box means for dividing the intertray spacing into dispersing and settling zones is flowed to a tray dispersing zone. The tray dispersing zone has a seal box including an aperture means and means for automatically varying the effective cross sectional area of the aperture means presented to the light phase substantially in accordance with variations in the level of the light phase beneath the tray. Relatively large variation in average light phase flow rate can then be accommodated as necessary for different feed rates or raffinate yields while maintaining the flow rate of the light phase substantially constant with time for any given operation (i.e., avoidance of undesirable cycling).

Abstract: THE CLARIFIED EXTRACT ISSUED FROM A SOLIDS-LIQUIDS SEPARATION ZONE (IN WHICH THE SOLIDS ARE SEPARATED FROM THE LIQUIDS OF A COAL LIQUEFACTION PRODUCT ACCORDING TO THE SIZE OF THE SOLIDS AND CONCENTRATED IN A SEPARATELY DISCHARGED SOLIDS SLURRY) IS IMPROVED BY ADDING TO THE COAL LIQUEFACTION PRODUCT A RECYCLE STREAM SELECTED FROM A FIRST FRACTION, BOILING WITHIN THE RANGE FROM ABOUT 100*F. TO ABOUT 700*F. AND RECOVERED FROM EITHER THE CLARIFIED EXTRACT OR THE CONCENTRATED SOLIDS SLURRY ISSUED FROM THE SEPARATION ZONE, AND A SECOND FRACTION, BOILING ABOVE ABOUT 1000*F. AND CONTAINING ASH SOLIDS RECOVERED FROM THE CLARIFIED EXTRACT. THE RECYCLE STREAM IS ADDED IN AMOUNTS OF FROM ABOUT 1 TO ABOUT 50 WEIGHT PERCENT OF THE FEED TO THE SEPARATION ZONE. IT HAS BEEN FOUND THAT EACH OF THESE FRACTIONS QUITE UNEXPECTEDLY ACTS AS AN AGGLOMERATING AGENT FOR PARTICULATE SOLIDS IN THE LIQUEFACTION PRODUCT, INCREASING THE SIZES OF THE PARTICLES TO SEPARABLE SIZED, THEREBY PROVIDING AN INCREASE IN THE CLARITY OF THE COAL EXTRACT ISSUING FROM THE SEPARATION ZONE.

Abstract: A replaceable coalescing cartridge, capable of use in any commercial coalescer, comprising an upstream coalescing section and a downstream bubble breaking section, transforms small diameter oil droplets into larger droplets without the formation of oil surfaced water bubbles. A coalescer, fitted with said cartridge, employing a honeycomb of curve-shaped settling ducts is provided.
