摘要: A device for taking an impression of the orifice edge profile of an orifice plate so that the edge sharpness can be measured, comprises a support bar having clamps for rigidly fixing the bar to the orifice plate, the clamps preferably being adjustable along the length of the bar, and a rocker arm pivotally mounted between its ends on a carriage which is slidable along the bar and which can be locked in any desired position on the bar. The bar carries at one end a holder for a piece of lead foil and at its other end a micrometer head having its spindle projecting into engagement with a stop which is fixed on the carriage. A spring acting between the rocker arm and the carriage biases the spring into engagement with the stop and hence screw adjustment of the micrometer head causes the rocker arm to pivot. In use the arm is pivoted to bring the lead foil into contact with the orifice edge of the orifice plate to be tested, and further pivotal movement causes the edge the foil to a measured to a measured amount.

摘要: Gases or liquids are steam desulphided in the presence of a catalyst containing a uranium oxide together with a thorium oxide and/or a cobalt oxide. Air may also be present. The process is useful for desulphiding inorganic gases, for example effluent gases and for desulphiding organic compounds such as oils.

摘要: A gas containing a high proportion of methane (e.g. 90 percent or more) is produced by (i) reacting a preheated mixture of steam and the vapor of a predominantly paraffinic hydrocarbon feedstock having a final boiling point of not more than 300* C. in the presence of a steam-reforming catalyst to give a gas containing methane, hydrogen, carbon oxides and undecomposed steam, the reaction zone being cooled by a heat exchanger; (ii) reacting the stage (i) product gas in the presence of a methanation catalyst to increase the methane concentration, the reaction zone being cooled by a heat exchanger, and (iii) removing steam and optionally carbon dioxide from the gas leaving stage (ii). Both stages are operated at as low a temperature as possible to maximize the production of methane. The heat exchangers are preferably fluid-cooled internal heat exchangers. The fluid coolant may be water or steam. Water may be used in stage (iii) to remove (by cooling) steam; passed into the stage (ii) heat exchanger and converted into steam; passed into the stage (i) heat exchanger; and then used as the process steam.

摘要: A PROCESS FOR THE PRODUCTION OF A GAS CONTAINING A HIGH PROPORTION OF METHANE (E.G. 90% OR MORE) COMPRISES: (I) INTRODUCING A PREHEATED MIXTURE OF STEAM AND THE VAPOUR OF A PREDOMINANTLY PARAFFINIC HYDROCARBON FEEDSTOCK HAVING A FINAL BOILING POINT OF NOT MORE THAN 300*C. (E.G. NAPHTHA) INTO A FIRST CATALYTIC REACTION ZONE IN WHICH THE MIXTURE REACTS IN THE PRESENCE OF A STEAM REFORMING CATALYST TO GIVE A GAS CONTAINING METHANE, HYDROGEN, CARBON OXIDES AND UNDECOMPOSED STEAM; (II) COOLING THE GAS PRODUCED IN STAGE (I) BY ADDING A FURTHER QUANTITY OF AT LEAST ONE OF THE REACTANTS; (III) INTRODUCING THE GASEOUS MIXTURE FORMED IN STAGE (II) INTO A SECOND CATALYTIC REACTION ZONE IN WHICH THE CONSTITUENTS OF THE MIXTURE REACT IN THE PRESENCE OF A CATALYST TO INCREASE THE PROPORTION OF METHANE IN THE MIXTURE; AND (IV) REMOVING STEAM AND CARBON DIOXIDE FROM THE GAS LEAVING THE SECOND CATALYTIC REACTION ZONE. THE GAS MAY BE USED AS A SYNTHETIC NATURAL GAS.
IN BOTH STAGES (I) AND (III) THE TEMPERATURE IS KEPT AS LOW AS POSSIBLE, DEPENDING ON THE CATALYST: FOR EXAMPLE, STAGE (I) MAY BE OPERATED AT A CATALYST BED TEMPERATURE OF 400-500*C., AND STAGE (III) SUCH THAT THE OUTLET TEMPERATURE IS 200-250*C., WHEN A LOW TEMPERATURE STEAM REFORMING CATALYST IS USED IN BOTH STAGES. THE REACTION ZONE IN STAGE (III) MAY BE INTERNALLY COOLED, AT LEAST AT THE OUTLET END OF THE ZONE. THE COOLING IN STAGE (II) IS PREFERABLY ACHIEVED BY ADDING COLD HYDROCARBON FEEDSTOCK.-

摘要: A PROCESS FOR THE PRODUCTION OF A GAS CONTAINING GASEOUS HYDROCARBONS BY THE HYDROGENATION OF NON-DISTILLATE HYDROCARBON OILS. THE OIL IS FIRST PREHEATED IN THE LIQUID PHASE, AND THEN INTRODUCED THROUGH AN ATOMISER INTO A GAS RECYCLE HYDROGENATOR IN WHICH THE OIL REACTS UNDER PRESSURE WITH, AND IS CONTINUOUSLY ENTRAINED INTO CIRUCLATION WITH, A SUPPLY OF HYDROGENATING GAS. A GAS CONTAINING GASEOUS HYDROCARBONS IS FORMED BY REACTION OF THE OIL AND THE HYDROGEN, AND IS CONTINUOUSLY WITHDRAWN FROM THE HYDROGENATOR. THE PROCESS IS PRIMARILY FOR THE HYDROGENATION OF NONDSTILLATE OILS, SUCH AS CRUDE PETROLEUM AND PARTICULARLY LIGHT CRUDE PETROLEUM.

摘要: A leak clamp assembly for repairing a leak in a spigot and socket joint in a gas pipe includes a split sealing ring of resilient material which is placed around the spigot and against the outer face of the socket and a split rigid backing-up ring which is also placed around the spigot on the side of the sealing ring remote from the socket and a series of clamps which act between the backing-up ring and the back face of the socket. The backing-up ring comprises at least two arcuate sections containing a bolt hole at each end, the sections being connected end to end to form the ring and overlapping at their junctions so that the corresponding holes are at least partly in register with each other. The clamps comprise bolts for passing through the pairs of overlapping holes and designed to engage behind the socket preferably with an anchor ring which is assembled around the pipe behind the socket. The bolts comprise a conventional shank for cooperation with a nut and a head which tapers to the shank, the arrangement being such that the backing-up ring section can be arranged with the bolt holes overlapping to a minimum degree around the shanks of the bolts to provide the backing-up ring with a maximum size, but on tightening the nuts on the bolts, the tapered heads are drawn into the overlapping holes thus increasing the extent of the overlap and drawing the backing-up ring sections further together until the backing-up ring tightly engages the sealing ring and clamps it around the spigot and against the face of the socket of the spigot and socket joint.

摘要: A furnace has a self-recuperative burner mounted in a port in a wall of the furnace so as to form a products passage to conduct products of combustion from the furnace chamber to outside the furnace. The burner includes an air passage which leads to a nozzle mounted in the inlet of a combustion chamber and which is in heat-exchange relationship with the products passage. The air passage extends at first forwards beyond the inlet of the combustion chamber and then rearwards to the nozzle so that the air-heating surface area is more effective and metal in the hottest part of the products passage is cooled.

摘要: IN A PROCESS FOR DESULPHURISING HYDROCARBON DISTILLATE OILS, A MIXTURE OF THE OIL VAPOUR AND A CARBON OXIDE-CONTAINING HYDROGENATING GAS IS PASSED OVER (A) A HYDRODESULPHURISATION CATALYST AND THEN (B) A MATERIAL CAPABLE OF ABSORBING HYDROGEN SULPHIDE AND RAPIDLY ELIMINATING ANY CARBONYL SUPHIDE PRESENT EITHER BY ABSORBING THE CARBONYL SULPHIDE OR BY CONVERTING IT TO HYDROGEN SULPHIDE AND ABSORBING THE HYDROGEN SULPHIDE. THE HYDROGENATING GAS MAY BE A LEAN GAS, A TOWN GAS, A RICH GAS, OR A SUBSTITUTE NATURAL GAS PRODUCED BY STEAM REFORMING THE DESULPHURISED DISTILLATE OIL. THE MATERIAL USED IN STAGE (B) IS PREFERABLY ZINC OXIDE. THE PROCESS IS CAPABLE OF ATTAINING A VERY HIGH DEGREE OF PURIFICATION (E.G. 0.2 P.P.M. OR LESS). WHEN A HIGH DEGREE OF PURIFICATION CANNOT BE ATTAINED BY USE OF A SINGLE PAIR OF STAGES (A) AND (B), THE DESIRED DEGREE OF PURIFICATION CAN BE ATTAINED BY PASSING THE MIXTURE OVER (C) A ZINC OXIDE-COPPER OXIDE COMPOSITION OR BY REPEATING THE STAGES (A) AND (B).
