Title: Improvements in the treatment of coal and other minerals
Inventor: MOSS GERALD
IPC: B03D1/04
Filed: 1964-06-11
Abstract: 1, 041, 547. Separating minerals by flotation. ESSO RESEARCH & ENGINEERING CO. May 28. 1965 [June 11, 1964; Dec.23, 1964; April 29, 1965], Nos. 24276/64; 52178/64; and 18139/65. Heading B2H. Coal or other mineral material is separated from an aqueous slurry (or suspension) by adding to the slurry a water immiscible organic liquid (volatile liquid) which has a higher surface affinity for the material than has water and a boiling point lower than that of water and then heating the slurry to a temperature below the boiling point of water but at or above that of the volatile liquid whereby the material is carried to the surface and removed therefrom. A slurry of coal is introduced into a mixing vessel 1 and then fed by a pump 2 into a vessel 5 which preferably contains an inert atmosphere, a pump 4 serving to mix with the feed naptha (the volatile liquid) drawn from a line 15 and fuel oil (an involatile liquid) drawn from a pump 19. A steam coil 20 provides the necessary heat to float the coal as agglomerages or froth for removal by a scoop 6 which feeds rotary screens 8, 9 having a discharge end extending through the end of the vessel. Naptha evaporation from the slurry is condensed in a condenser 13 cooled by a refrigerating coil 14. The ash content is drawn from the bottom of the vessel through a line 16 as a slurry and passed through a filter 17 which discharges the ash through a line 18 and returns the water to the mixing vessel 1. The addition of fuel oil at 19 serves to prevent re-wetting of the coal by water as the naphtha evaporates and to facilitate de-watering in the screens 8, 9. A surface active compound may be added in addition to, or in place of, the fuel oil for the same purpose. Furthermore, the pH of the slurry may be adjusted by the addition of lime or sodium carbonate and air or other gas used to assist flotation. Instead of the screens 8, 9 a suction filter or weir may be employed. Other volatile liquids which may be used include benzene, benzene homologues, straight chain hydrocarbons and naphthenes. The involatile liquid (fuel oil) may be, for example, kerosene, gas oil, residual fuel oil, phenol extracts or coal tar. Flotation reagents may include oleic acid, sodium carbonate, lime, sodium ethyl xanthate, sodium alkyl sulphates, sulphuric acid, dextrin, starch, terpineol and phenol.

Title: Fluid treating apparatus and process for treating fluid
IPC: B01D3/06
Filed: 1946-08-19
Abstract: <PICT:0636324/III/1> <PICT:0636324/III/2> In distilling a mixture of liquids, e.g. in the decontamination of used oils such as lubricating, transformer or heat treatment oils, the liquid is heated and sprayed into an evacuated chamber, heat being supplied to the spray zone sufficient to compensate for the heat of vaporization and expansion.  A sweeping agent, such as steam or an inert gas such as nitrogen, may be introduced into the evacuated chamber.  The bottom part of the evacuated chamber may be exposed so as to be unheated. Additional surfaces on to which the spray is directed may be provided within the chamber so that evaporation takes place from the liquid films formed thereon. The evacuated chamber may be heated by internally or externally disposed heating means and, when heated by liquid or gas jacket, the liquid to be sprayed may be preheated by passage through a pipe coil disposed within the jacket.  In one of the various forms of apparatus illustrated, Fig. 2, a jacket 16 containing liquid heated by a steam coil 17 surrounds an evacuated chamber 14 into which the liquid mixture, preheated by passage through coil 24, is sprayed through nozzle 25 and meets steam, sprayed in through nozzle 13, which acts as sweeping agent. Condensate is collected through pipe 21.  In another form, Fig. 11, the evacuated chamber is lagged, except for the bottom, and is heated by an internal steam coil 37.  The spray 34 is directed at two conical perforated surfaces 40, 41 between which are small particles such as glass beads or material such as glass wool.  The purified oil, or other residual liquid, passes through a heat exchanger 44 which, in conjunction with heater 45, preheats the liquid.  The Specification as open to inspection under Sect. 91 comprises also the degasification of beverages and the condensation of fruit juices-in which cooling before spraying may be adopted.  This subject-matter does not appear in the Specification as accepted.
