Title: Improvements in or relating to transport and storage of liquefied gases
Inventor: RIGBY RICHARD
IPC: F17C11/00
Filed: 1963-03-05
Abstract: 1,027,678. Storing liquefied gases. SHELL RESEARCH Ltd. March 5, 1963, No. 8714/63. Heading F4P. [Also in Divisions B1 and F1] A method of storing liquefied gas at atmospheric pressure comprises floating the liquefied gas on a second inert liquid in which the liquefied gas is at least partially soluble and which has at a temperature not exceeding 60‹ C. a vapour pressure not exceeding one atmosphere and a density greater than that of the liquefied gas, and condensing liquefied gas which has vaporized due to heat transferred from the second liquid and returning the condensate to the body of liquefied gas. Over a period the temperature of the second liquid is reduced with consequential dissolution of the liquefied gas in the second liquid until a temperature may be reached at which the liquefied gas is fully dissolved in the second liquid. Examples of liquefied gases which may be stored are acetylene, ethylene, ethane, propane, propene, nbutane, iso-butane, n-butene, iso-butene and mixtures thereof, and examples of the second liquid are crude-petroleum, topped crude, residual fuel oil, lubricating oil distillates, catalytically cracked cycle oil, thermally cracked gas oil, straight run gas oils, kerosines, heavy gasoline fractions and mixtures thereof. Fig. 4 shows liquefied gas 10 floating on a carrier liquid within a tank 1 flanked by wing tanks 2, 3 of a ship, the liquefied gas being confined within a rectangular skirt retainer 11. The retainer 11 may be supported from the roof, sides or bottom of the tank 1; it may have perforations therein and may be provided with a perforated bottom plate. A floating suction member 25 communicates by means of a conduit 26 with a cyclone 27 having a part 28 communicating with a vacuum source (not shown) and a port 29 communicating with a pump 30, whereby the liquefied gas may be discharged from the ship; gas formed during discharge of the liquefied gas may be condensed. Alternatively, the liquefied gas may be discharged by an electrically-operated submerged pump 35 having a floating suction 36. A condenser 6 is provided for condensing the liquefied gas which has been vaporized during storage, the condenser having a vent 5 for entry of gas to the condenser and for return of the condensate to the tank 1. The latter is loaded with liquefied gas by means of a swing- arm which is slowly raised to ensure delivery of the liquefied gas to the surface of the carrier liquid with minimum kinetic energy. In a second embodiment, Fig. 3, the skirt retainer 11 is replaced by a floating pan retainer 17 which is restrained to move in a vertical direction by runners 20 directed by guides 18 extending from the roof to the floor of the tank 1. Dissolution of the liquefied gas in the carrier liquid takes place by vapour contact. The retainer 11 or 17 may be dispensed with.

Abstract: 559,360. Ammonium sulphate. SEMETSOLVAY ENGINEERING CORPORATION. July 10, 1941, No. 8721. Convention date, Sept. 25, 1940. [Classes 1 (ii) and 32] In a process for producing ammonium sulphate from coke oven or inert gases containing ammonia the gases are passed in heated condition and at a humidity of at least 70 per cent. into a scrubber in counter current to a solution of ammonium sulphate and sulphuric acid to produce ammonium sulphate, the solution being then cooled and concentrated under vacuum and brought into contact with crystals of ammonium sulphate on which ammonium sulphate from the solution is deposited. Part of the solution of ammonium sulphate and sulphuric acid may be recirculated into contact with additional gas before concentration and crystallization. A flow system is described in which an exhauster is employed to withdraw coke oven gas and force it through the scrubbing column and steam from an engine driving the exhauster is condensed to produce a vacuum for cooling and concentrating the ammonium sulphate solution. Ammonia gas may be absorbed from the coke oven gas in water and then freed therefrom and used to neutralize the acid solution of ammonium sulphate. The crystallizing apparatus may be of the form shown in Fig. 3 in which the solution to be crystallized is discharged through inlet 54 adjacent to a pump inlet 57 from which it is circulated to an evaporative cooling chamber 61 and passes thence below a perforated plate 67 on which the crystals accumulate and from which they may be withdrawn through a conduit 68 to a receptacle 72. In a modification the perforated plate is dispensed with.

Title: Improvements in and relating to the production of zirconium and titanium oxides
IPC: C01G25/02
Filed: 1940-05-21
Abstract: 541,343. Titanium and zirconium oxides and chlorides. SCHORNSTEIN, W. O. H. May 21, 1940, No. 9015. [Class 1 (iii)] Titanium and zirconium oxides in a finelydivided state suitable for use as pigments are obtained by subjecting the vapour of the chlorides to the action of oxygen at a temperature above 800‹C. in an enclosed chamber under conditions which prevent the reagents from contacting with the walls or other solid obstruction before the reaction is complete and of such dimensions that the gases pass through the chamber at less than one hundredth of the entering velocity. The temperature is attained by preheating the entering streams of gas and vapour. The chloride vapour which may be diluted with inert gas, and air or oxygen enter by concentric pipes 3, 2 at the centre of the side wall of the reaction chamber 6 and are pre-heated by a muffle furnace 4 to a temperature of 800-1000‹C. The oxide falls down a hopper 9 and gases are withdrawn through a filter bag 7 of glass. cloth &c. If zirconium chloride is' treated at 800-900‹C moisture is added to the gases. Impure chlorides obtained by treatment of ores of titanium or zirconium are subjected to purification treatments as described in Specification 487,834, consisting in heating with a reducing agent to transform the chlorides and oxychlorides of other metals. e.g. ferric and vanadyl chlorides into compounds of a lower state of chlorination and higher volatilization temperatures and fractionally condensing the vapours. The reduction is effected in the case of chlorides by admixing the vapours with hydrogen and in the case of oxychlorides by passing the vapours over charcoal or coke in which hydrogen may have been occluded.
