Title: Improvements relating to the extraction by organic solvents of sulphur from material containing free sulphur and inorganic compounds
IPC: C01B17/033
Filed: 1945-12-05
Abstract: <PICT:0608143/III/1> A process for the recovery of sulphur from an aqueous paste of sulphur-containing material, especially mixtures of sulphur and iron compounds, such as the settled, filtered or otherwise partially de-watered crude sulphur obtained in gas purification by washing with aqueous iron oxide suspensions consisting of sulphur containing up to 50 per cent by weight of water, comprises treating the paste with a solvent consisting mainly or entirely of aromatic hydrocarbons boiling between 100 DEG  C. and 140 DEG  C., such as toluene or xylene or a mixture of these, or the aromatic hydrocarbons obtained in admixture with paraffins and olefins from coal gas, preferably the fraction with a boiling range approximating closely to that of toluene or xylene, and removing the water from the sulphur paste as a low boiling mixture with the solvent, the mixture of water and solvent vapour being condensed and separated, and the solvent returned to the system.  In one embodiment the aqueous sulphur paste is fed from a hopper to the steam jacketted kettle 13 provided with perforated shelves 16 affording maximum exposure to hot solvent entering through 17, 18 which boils freely in contact with paste giving a mixture of steam and solvent vapour which passes to condensers 27, 28, thence to a distillate separator 31 whence the water is continuously discharged, the sulphur forming a solution which, with the suspension of inorganic compounds, falls to the cone-shaped bottom 15 of the kettle 13.  The sulphur solution passes to the steam jacketted separator 19 which is in hydraulic balance with the kettle 13, wherein the inorganic compounds settle in the conical base 21 whence they may be discharged to receiver 22, while clear sulphur solution passes continuously to the evaporator 23 having steam chest 24 and vertical boiling tubes 25 wherein sulphur separates as crystals or liquid depending on the boiling point of the solution, which may be fixed by choice of suitable solvent, or may be kept above the melting point of sulphur by admitting live steam at 26 to promote boiling at a reduced temperature.  Mixed vapours from the evaporator 23 pass to the condensers 27, 28 and distillate separator 31 as before, whence the solvent is returned to kettle 13.  The sulphur is collected in receiver 31a and this and the solid matter in receiver 22 are deprived of their solvent content before discharge by blowing live steam through the masses.  In this arrangement provision is made for the removal of a portion of the circulating solvent from time to time for redistillation in a regenerator to remove tar fouling the solvent; solvent vapour from the regenerator is returned to the condensing system described.  In an alternative arrangement, the kettle and separator are combined in a single steam jacketted vessel which is more economical thermally.

XXVI] A complete section of a ship's ventilation ducting containing an axial flow fan and its driving motor is hinged to the remainder of the ducting on an axis parallel to that of the section but outside the section, while the remainder of the ducting incorporates a connecting structure which renders the ducting rigid without preventing the hinged section from being swung aside. The driving motor 22 is carried within a section 21 of ventilation ducting by means of spider arms 24. To ensure clearance around the impeller 23, the arms 24 have a screw adjustment and external flanges 25, 26 may be welded to the section 21 to preserve the circular section. Hinge lugs 27, 28 welded to the section 21 are secured to a hinge bar 29 carrying nuts 31 having spigots which engage in lugs 17, 18 to act as hinge pins. The nuts are secured in adjusted position by lock nuts 32. The lugs 17, 18 are carried by a bar 12 which, together with a similar bar 13, connects a pair of flanged end rings 11. The remainder of the ducting is bolted to the end rings 11. A semicylindrical wall 16 extends between the bars 12 and 13 and is desirably welded to them and to the end rings 11. Flexible leads 42 run from a terminal box 19 and through a pipe 43 to the motor 22. Alternatively, the leads may pass through the hinge bar 29, which is then hollow. When the section 21 is swung out into the position shown in Fig. 3, it is held by a cable 44. A handle 33 is provided. When the section 21 is in the closed position shown in Fig. 1, it is fastened in place by bolts 34, Figs. 1 and 5, passing through the bar 13 and lugs 35. A similar arrangement may be provided on the hinge side. Rubber members 36 make airtight joints between longitudinal members 37, 38 and the bars 12, 13 respectively. A rubber gasket 39 laps over the flange 14 of each end ring 11 and the adjacent end of the section 21 and is held in place by metal straps 41 bolted to the ends of the members 37, 38. To avoid gaps at the ends of the members 37, 38, either the ends of the members 36 may be extended inwards to reach the wall of the section 21 or the gaskets 39 may be carried through slots in the members 37, 38 and extended radially outwards as far as the members 37. Alternatively, the member 36 may be replaced by a gasket similar to the gasket 39, backed by a single and preferably wide strap secured to the remaining part of each flange 14 adjacent the wall 16.
