Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.-

Abstract: 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.

Abstract: SULPHUR IS PRODUCED FROM GASEOUS MIXTURES OF HYDROGEN SULPHIDE AND SULPHUR DIOXIDE BY CONTACT WITH A CATALYST COMPRISING AN OXIDE OF URANIUM PREFERABLY ADMIXED WITH A THORIUM OXIDE AND PREFERABLY DISPOSED ON A CARRIER. IF STEAM TOGETHER WITH CARBON OXYSULPHIDE AND/OR CARBON DISULPHIDE ARE PRESENT, THE CARBON SULPHIDES WILL REACT WITH STEAM IN THE PRESENCE OF THE CATALYST TO YIELD HYDROGEN SULPHIDE. THIS LATTER REACTION MAY TAKE PLACE SIMULTANEOUSLY WITH THE REACTION OF HYDROGEN SULPHIDE AND SULPHUR DIOXIDE.
