    摘要: A method is provided for the extraction of hellium of high purity, and high yield, with intermediate enrichment in refrigerating plants, from gases containing very low helium concentrations, by an alternating pressure adsorption process. the helium containing gas is fed cyclically in each of three adsorption stages into four adsorbers connected in parallel. First, higher hydrocarbons and other impurities are trapped in adsorbers (J, K, L, M) filled with activated charcoal in a preliminary filtering stage. Other gaseous components, for example nitrogen and/or methane are trapped in adsorbers (A, B, C, D and E, F, G, H) filled with carbon molecular sieves, in two subsequent adsorption stages. The helium is first enriched in stage (I) and then extracted in stage (II) as refined helium with a helium content of 99.9%. The gas used is preferably natural gas with a 2 to 10% helium content. The refined helium so produced can be used, for example as a blanket gas, a breathing gas for divers, a balloon gas and as a carrier gas in chromatography.

    摘要: A method is provided for extracting helium from a relatively helium poor gas mixture through a pressure swing adsorption process which adhieves an enriched product gas containing over 50% helium. The gas mixture to be enriched is fed cyclically to four adsorber vessels ranged in parallel which successively pass through a pressure build-up, an adsorptive and a pressure relief phase, with pressure build-up and relief being in part brought about by pressure compensation with any one of the other adsorbers. The pressure-build up and relief phases include a series of three and four, respectively, steps involving alternating pressure levels. As a preliminary treatment, the process may include an initial step wherein the unenriched gas mixture is first fed through a series of pre-filters filled with activated carbon for removing higher hydrocarbons.

    摘要: A device for weakening the right hand grip on a golf club in order to allow better extension in a swing for the left arm and club shaft. A body has three identations, two to be gripped by the thumb and middle finger of the right hand and a third indentation disposed between the other two for accepting the width of the golf club shaft. The body is gripped by the thumb and middle finger of the right hand and the third indentation is placed against the club shaft. The resulting grip maintains the positioning of a standard grip while at the same time weakening the right hand strength.

    摘要: The disclosed hybrid membrane and pressure swing adsorption process can recover helium from source streams of about 0.5 to 5 percent by volume helium and concentrate the helium to a concentration of greater than about 98 percent by volume. The process comprises a membrane separation followed by two stages of pressure swing adsorption which are used in series. The source gas will primarily contain hydrocarbons but will contain some nitrogen. The membrane unit will contain a semipermeable membrane which is permeably selective for helium and will to the extent feasible reject hydrocarbons. The permeate gas will be increased in helium content by 2 to 10 times. Part of the residue gas is used in the regeneration of the adsorbent beds in the first stage of pressure swing adsorption. Each stage of pressure swing adsorption will contain a plurality of adsorbent beds, and will be cycled through multiple phases. In the first stage the adsorbent beds will sequentially undergo the phases of adsorption, recycle, depressurization, evacuation, helium pressurization and recycle feed pressurization. The product gas from the first stage is flowed to the second stage and in the second stage sequentially will undergo the phases of adsorption, depressurization, evacuation, purge, and helium pressurization. The offgas from the evacuation and purge in the second stage is flowed to input to the first stage. The process efficiently produces a product stream with a helium content of more than 98 percent by volume.

    摘要: The disclosed pressure swing adsorption processes can recover helium from source streams of less than about 10 percent by volume helium and concentrate the helium to a concentration of greater than about 98 percent by volume. Two stages of pressure swing adsorption are used in series. The source of the helium gas will be natural gas wells. The source gas will contain hydrocarbons but in most instances the primary gas other than helium will be nitrogen. Each stage of pressure swing adsorption will contain a plurality of adsorbent beds, and preferably about four. In each stage the adsorbent beds will be cycled through multiple phases. In the first stage the adsorbent beds will sequentially undergo the phases of adsorption, recycle, depressurization, evacuation, helium pressurization and recycle feed pressurization. The product gas from the first stage is flowed to the second stage and in the second stage sequentially will undergo the phases of adsorption, depressurization, evacuation, purge, and helium pressurization. The offgas from evacuation and purge in the second stage is flowed to input to the first stage. The processes using an adsorbent that adsorbs the gases other than helium produces a product stream in a high volume with a helium content of more than 98 percent by volume.

    摘要: A natural gas feed stream containing significant quantities of nitrogen can be increased to a content of greater than 95 percent by volume of natural gas, and preferably greater than about 98 percent, by passing the natural gas feed stream sequentially through at least four adsorbent beds which are cycled through six phases comprising an adsorption phase to adsorb natural gas, a recycle phase to remove feed gas from the voids in the adsorbent bed and nitrogen from the adsorbent by the passage of a depressurization gas therethrough to produce a recycle gas, a depressurization phase to reduce the adsorbent bed pressure to about ambient and to produce the depressurization gas, an evacuation phase where the pressure in the adsorbent is further reduced and an enriched natural gas product stream recovered, a pressurization phase where the pressure in the adsorbent bed is increased using nitrogen gas from a bed in an adsorption phase, and further pressurizing the adsorbent bed in a recycle feed pressurization phase by the flow of the recycle gas therein.
