Title: Method of recovering sulphur from gases
IPC: C01B17/04
Filed: 1931-04-11
Abstract: Sulphur is obtained from gases containing carbon bisulphide or carbon oxysulphide or both by oxidation with gases containing free or combined oxygen, the gases being brought into contact with a heated refractory material impregnated with an iron compound.  The reaction temperature should be kept above 600 DEG  C.; preferably, temperatures between 800 DEG  and 900 DEG  C. are employed, but 1000 DEG  C. may be used.  Air or sulphur dioxide may constitute the oxidizing gas, enough oxygen being present to convert the whole of the carbon to dioxide without any excess of oxygen.  As the reactions are exothermic, the temperatures are controlled by the use of jackets and heat exchangers.  As the reaction surface, firebrick or other refractory material impregnated with ferric oxide is employed, this being prepared by soaking the firebrick in a solution of an iron salt, drying and igniting at gradually increasing temperatures; the final temperature should be at least 800 DEG  C., preferably 1000 DEG C.  The impregnated material is packed loosely in the reaction vessels which preferably are narrow cylinders so built into a chamber that heat exchange can take place between the gases being treated and other gases, e.g. the oxygen containing gases for the reaction.  The gases, which should be free from dust, may be passed at a rate exceeding 100 cubic feet per hour for each cubic foot of space in the reaction vessel. To avoid explosion, the sulphur-containing gases and the air &c. should be admitted independently.  A yield of 90-95 per cent is obtained but this can be increased by operating in two stages, 80 per cent of the oxygen required being used in the first stage and the remainder in the second.  In starting the reaction, the proportion of the oxygen-containing gases should be restricted since some oxygen may be removed from the material in the reaction chamber. Removal of the sulphur is effected by cooling the gases, preferably by water under a pressure which will produce the temperature required to obtain the condensed sulphur as a mobile liquid, the steam generated being employed as required.

Abstract: 1,271,210. Lubricator. ITT FLUID HANDLING Ltd. 25 March, 1971, No. 7780/71. Heading F2A. A drip feed lubricator comprises a gas-tight lubricant reservoir I with a feed passage 2 extending from the reservoir to a lubricant supply port 4. A passage 6 is provided between the port 4 and the reservoir in order to equalize the pressures. The lubricant feed passage is closed by a needle valve 5 which is biased against its seat by a spring 23 acting on the flexible top of the reservoir to which the needle valve is fixed. The lubricator is fixed on the apparatus to be lubricated by a fluid-tight connection so that when a pressure greater than ambient pressure exists in the apparatus, the needle valve is lifted from its seat due to the pressure in the reservoir increasing to the same pressure as exists at the lubricant port, and deforming the flexible top of the reservoir. Lubricant thus flows under gravity through the passages 3 and 2 to the supply port and drips into the apparatus. The movement of the needle may be limited by a screw 24 and a sight glass 34 may be mounted in the connection with the apparatus.
