Abstract: 1,184,166. Sweetening hydrocarbon distillates. UNIVERSAL OIL PRODUCTS CO. 17 April, 1968 [20 April, 1967], No. 18073/68. Heading C5E, Mercapto sulphur compounds contained in a hydrocarbon distillate are oxidized in the presence of an alkaline reagent, a phthalocyanine catalyst and oxygen in an amount of less than 1'4 times that stoichiometrically necessary to oxidize all the mercapto compounds to the corresponding disulphides. The distillates treated are kerosenes, stove oils, furnace oils, solvent oils, diesel fuels, lubricating oils, jet fuels, straight-run gasolines, cracked gasolines and heavy naphthas. Naphthenic acids and hydrogen sulphide can be washed from the feed with dilute caustic solution. The catalyst comprises either 0À005-10 wt. per cent of a phthalocyanine of Co, Va, Fe, Cu, Ni or Cr on a carrier of activated charcoal, coke, silica, alumina or magnesia or an aqueous solution of the sulphonated or carboxylated derivatives of these metal phthalocyanines. The alkaline reagent generally comprises an aqueous solution of 1- 50 wt. per cent of caustic soda, caustic potash, lithium hydroxide, rubidium hydroxide or cesium hydroxide but alcoholicalkalicanbeused.Sodium isobutyrate, ammonium hydroxide or dimethylsulphoxidemay be included in the alkaline reagent as a solutizer. The oxygen content can be controlled by removing excess dissolved or entrained oxygen from the distillate feed with nitrogen or by adding oxygen as air or dissolved in the hydrocarbon feed or alkaline reagent. The reaction is carried out at up to 204 C. and 0 68 to 10.2 atm. gauge.

Patent GB-593680-A (GB)
Title: Improvements in cells for the electrolysis of magnesium chloride fusions
IPC: C25C3/04
Filed: 1943-11-03
Abstract: 593,680. Electrolysis. MATHIESON ALKALI WORKS. Nov. 3, 1943, No. 18252. Convention date, Nov. 21, 1942. [Class 41] In a fusion process for obtaining metallic magnesium, in which the make-up magnesium chloride salt is added in hydrous form to the fused electrolyte in a feed chamber where it is converted to the hydroxy chloride by the high temperature, the mixture is, before passing to the electrolysis chamber, superheated in a special chamber to eliminate the water-content. The cell comprises an electrolysis chamber A communicating by a passage 34 with a feed chamber B, in turn communicating by a passage 22 with the superheating chamber C which communicates by passage 24 with chamber A. The hydrous make-up salt is introduced into B by a pipe 27 and a pipe 28 leads off the gases produced. A connection 29 admits chlorine, hydrochloric acid, or a mixture of chlorine and carbon monoxide or carbonyl chloride to suppress decomposition of magnesium chloride. Electrodes 30 ... 33 fed by A.C. transformers keep the fusion at the correct temperatures, that is, 725‹ C. in chamber B and 800-850‹ C. in chamber C. Thermal effects may be relied upon for producing continuous circulation of the electrolyte, the flow being controlled by valves 26, 43 in the passages 34, 24 respectively. It is usually necessary, however, to rely upon a gas lift, as by introducing through a pipe 25 an inert gas such as nitrogen, or the gases referred to above in connection with pipe 29. By closing the valves periodically, and then opening them and energizing the gas lift, an intermittent flow can be set up. The fusion of mixed magnesium and alkali chlorides fills chamber A up to the lower edges of webs 16 separating the carbon anodes 14 from the liftable cathodes 15. Chlorine is drawn off from the spaces between the webs by connections 19 and molten magnesium is extracted from the cathode-space at 20.

Abstract: 1,069,853. Sterilizing and canning food. SWIFT & CO. May 6, 1964, No. 18804/64. Headings A2B and A2D. A method of sterilizing and canning food at superatmospheric pressure conditions comprises heating the food to 225‹-400‹F. while maintaining, superatmospheric pressure conditions to prevent boiling of the food, maintaining the said temperature and pressure for a period up to 240 seconds to ensure sterilization of the food, flash deaerating the food to a reduced superatmospheric pressure inducing a drop of no more than 200‹F. and filling the food which has been diluted at some previous point in the process, into containers at superatmospheric pressure. As shown, suitable apparatus comprises hopper 12 from which food is pumped along conduit 16 in which it is injected with steam from line 28, to heat exchanger 34 in which the material is heated. The food is sterilized as it is passed along conduit 36 in which the food receives hot water from nozzle 54. The diluted food is passed to flash deaerator 80 and then to can filling and sealing chamber 10 in which the food is fed into cans at 130 supplied by conveyers 140, 152, and the lids are applied to filled cans at 166 and closed at 168. The sealed cans are then passed through heater 182 to maintain the cans at the filling and sealing temperature to sterilize the cans. The cans are cooled at 184. The steam injection step may supply sufficient heat for the sterilization of the food and sufficient steam for the dilution requirements. In chamber 10, non pumpable food may be sterilized, cooked and added to the cans together with the sterilized pumpable food. The system may be provided with valves such as 22, 24, 70, 72, 74 and 132 for returning the material to hopper 12 or removing material from the system.
