摘要： Natural gas containing elemental sulfur dissolved therein is freed of the sulfur by introducing an ascending annular current of a mineral oil into an ascending flow of natural gas. The mineral oil has a viscosity of 2-200 cP and a vapor pressure of up to 3 X 10 1 mm Hg at 20*C. The sulfur is transferred from the natural gas into the mineral oil. To insure substantially complete transference, the ratio of mineral oil in liter/hr to natural gas in Nm3/hr should be maintained at 1: about 4-20.

摘要： A PROCESS FOR THE PRODUCTION OF METHANEE FROM CARBONACEOUS FUELS OF GREATER MOLECULAR WEIGHT THAN METHANE BY A NON-CATALYTIC, DIRECT PARTIAL OXIDATION REACTION IN WHICH THE CARBONACEOUS FUEL AND OXYGEN ARE REACTED IN THE PRESENCE OF HYDROGEN AND CARBON MONOXIDE, OPTIONALLY WITH THE ADDITION OF STEAM, AT AN AUTOGENOUS TEMPERATURE IN THE RANGE OF 1200 TO 2200* F. AND AT A PRESSURE IN THE RANGE OF 300 TO 4500 POUNDS PER SQUARE INCH. CARBON MONOXIDE AND HYDRROGEN FROM THE PRODUCT ARE PREFERABLY TOTALLY RECYCLED TO THE REACTION SO THAT ULTIMATE PRODUCTS OF THE PROCESS ARE METHANE, CARBON DIOXIDE, AND HYDROGEN SULFIDE IF THE CARBONACEOUS FUEL CONTAINS SULFUR. SUBSTANTIALLY PURE METHANE, SUITABLE AS FUEL GAS OR PIPELINE GAS MAY BE PRODUCED FROM RELATIVELY LOW GRADE FUELS AND TRANSPORTED BY PIPELINE TO POINTS OF COMSUMPTION.

摘要： A METHOD OF TRANSPORTING NATURAL GAS INCLUDING THE STEPS OF TRANSPORTING BULK VOLUMES OF NATURAL GAS IN THE FORM OF A LOWER ALKYL AMINE TO APOINT REMOTE FROM A POINT OF ORIGINATION, DECOMPOSING THE LOWER ALKYL AMINE AT THE POINT OF DESTINATION TO METHANE, AMMONIA AND NITROGEN, AND THEN SEPARATING THE METHANE FOR UTILIZATION. THE LOWER ALKYL AMINE CAN BE THERMALLY DECOMPOSED, OR IT CAN BE DECOMPOSED BY CATALYTIC HYDROGENATION. THE NITROGEN CONTENT OF THE AMINE CAN BE RECYCLED ON THE RETURN TRIP OF THE TRANSPORTING VESSEL AS AQUEOUS AMMONIA FOR RE-USE, OR IT CAN BE USED AS A HYDROGEN SOURCE IN THE RECONVERSION OF THE AMINE TO NATURAL GAS.

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.
