摘要： A liquid gas mixture containing methane is pumped at a pressure below the critical pressure of methane through a heat exchanger in the top part of a rectifying column to reliquefy methane vapor prior to discharge of the mixture into the lower part of the rectifying column, while liquid enriched in higher boiling components of the mixture accumulating at the bottom of the column is heated. The reliquefied methane withdrawn from the column may be pumped at the pressure desired for its utilization.

摘要： An improved tray for rectifying and scrubbing columns is simply constructed by providing a cylindrical member coaxially within the column shell, placing beams radially between said member and shell, attaching one end of each beam to said member or shell, supporting the opposite free end of each beam on a ring fastened to the vertical surface adjacent to said free end, and fitting tray segments in locking arrangement between the beams which are circumferentially spaced from each other. The free ends of the beams supported on the ring, together with the locked-in tray segments, can move radially to accommodate differences in thermal expansion of the components of the column.

摘要： A PROCESS FOR RECOVERING HYDROGEN FROM A REFINERY OFF GAS BY PROGRESSIVE REDUCTION IN TEMPERATURE OF THE GAS AND SUCCESSIVE REMOVAL OF RESPECTIVE CONTAMINANTS THEREFROM BY CONDENSATION THEREOF. AT LEAST SOME OF THE CONDENSED CONTAMINANTS ARE EXPANDED AND EMPLOYED AS A REFRIGERATING FLUID IN THE PROCESS. METHANE WHICH PRECIPITATES OUT AS SOLID IN THE FINAL STAGE OF HEAT EXCHANGE IS REMOVED IN AN ALTERNATING EXCHANGER PURGE ARRANGEMENT. IN A HYDROGEN PURIFICATON SYSTEM, A PORTION OF THE PURIFIED HYDROGEN ISMIXED WITH THE CONDENSED HYDROCARBONS SEPARATED FROM THE CRUDE HYDROGEN AND THIS MIXTURE IS USED TO COOL THE CRUDE HYDROGEN TO BE PURIFIED.

摘要： An apparatus for the heating, melting, welding, brazing, cutting and the like of a workpiece with the aid of the optical projection of a radiation source. The radiation source is disposed within a radiation focusing chamber at one focal point thereof and the radiation therefrom exits the chamber through a radiation outlet to impinge on a second external working focal point. A pressurized gas, which may be a cooling gas, protective gas or reactive gas may be introduced into at least a portion of the chamber. The gas discharges through the radiation outlet and prevents entry into the chamber of damaging vapors which develop during use of the apparatus. The chamber may be divided by a radiation permeable partition into a pair of compartments; a first containing the radiation source and a second having the radiation outlet. The gas may be introduced into the first compartment to exit through an aperture in the partition into the second compartment for discharge through the outlet. Alternatively a first gas may be introduced into the first compartment and a second gas may be introduced into the second compartment whereby both gases, either mixed or unmixed are discharged through the outlet. In other embodiments, the first compartment may be sealed and the gas or gases introduced directly into the second compartment. The second compartment may include a narrow tube disposed substantially coaxial with an imaginary line interconnecting the foci for directing a concentrated stream of a gas toward the workpiece. A fiber optic rod may be mounted at the radiation outlet to provide a concentrated radiation at a point removed from the second focus. The rod may have a bore for passage of the pressurized gas from the chamber.

摘要： A method and machine for rapidly heating an open-ended tube in a furnace provides for placing the tube on a support inside a tunnel furnace and projecting the flame of a burner through one of the tube ends into the interior of the tube. The burner thus will act as an injector drawing the exhaust gases, that exit at the other tube end, around to return outside the tube and to reenter the tube at the one end.

摘要： Natural gas containing nitrogen is cooled and liquefied by a cascade system having two closed refrigeration circuits operating on multicomponent refrigerant mixtures. The liquefied gas is distilled into three fractions: nitrogen, a mixture of nitrogen and methane, and liquid natural gas substantially free of nitrogen. The mixture of nitrogen and methane provides the refrigerant in a third and coldest open circuit of the cascade system to subcool the liquid natural gas to storage temperature.
