Abstract: Natural gas may be purified by removing C3+ hydrocarbons and CO2 in respective one or more separation units to yield conditioned gas lower in C3+ hydrocarbons and CO2 in comparison to the un-conditioned natural gas. Notably, the feed gas need not be subjected to joule-thomson expansion and molecular sieve dehydration performed by conventional processes. Rather, any water-rich reject stream from the separation unit(s) is dried downstream with a smaller compressor and smaller molecular sieve or gas separation membrane dehydration unit before it may be re-injected deep underground or deep under the sea bed.

Abstract: Parallel membrane elements are arranged in parallel within a pressure vessel. A sealing body is disposed within the pressure vessel and is compressed against an inner surface of the pressure vessel to provide a leak-right seal in between a feed gas side of the sealing body and a non-permeate side of the sealing body. The sealing body may be slid within the pressure vessel without damaging the sealing body and in all cases without requiring mechanical assistance.

Abstract: A gas separation membrane module includes a seal between a higher pressure gas and a lower pressure gas. The seal includes a compressible sealing member in between sealing surfaces. At least one of the sealing surfaces has corrosion-resistant cladding provided over either low alloy steel or high alloy steel. The cladding reduce the possibility of a seal failure due to corrosion of low alloy or high alloy steel exposed to acid gases or condensed moisture containing acid gases dissolved therein while at the same not requiring that all surfaces of the membrane module exposed to acid gases be provided with cladding.

Abstract: A burner and/or injector panel apparatus includes a flange rotatable within a cylindrical aperture in a horizontal plate and securely retainable between one or more retaining clips and the plate. Extending downward from the flange is a main body with a cylindrical chamber. A burner, burner/injector, or injector is contained within the cylindrical chamber. The main body has a helical cooling circuit extending around the cylindrical chamber and burner and/or injector. The burner and/or injector panel apparatus may be installed through a furnace wall, especially an electric arc furnace, more particularly, a balcony panel of a sump area of an electric arc furnace. The burner and/or injector panel apparatus may be tilted from horizontal or rotated around its vertical axis in order to better target a target area of a molten bath of metal with a flame, jet of oxygen, or stream of carbon particles.

Abstract: A cylinder caddy, adapted to a bottle with a neck, a bottom, and a center of gravity is provided. The caddy has a strap configured to affix circumferentially to the cylinder at a location higher than the center of gravity, and at least one axial strap configured to connect the strap. The caddy includes a handle with a first end pivotally attached to the upper strap, and a second end configured to detachably connect to the neck. In a first position, the handle is pivoted to allow the second end to be attached to the neck, thereby requiring the removal of a regulator, protecting the neck from dust and other particulates and allowing a user to safely carry the cylinder. In a second position, the handle is pivoted to allow the second end form a strut, thereby providing the user a more stable operating position.

Abstract: Helium-containing natural gas is processed with three gas separation stages to produce a natural gas product and a Helium-containing gas that may be injected into the reservoir from which the Helium-containing natural gas is obtained. A permeate from the first gas separation membrane stage is compressed and fed to the second gas membrane stage. The permeate from the second gas separation membrane stage is recovered as the Helium-containing gas that may be injected into the reservoir. The non-permeate from the second gas separation membrane stage is fed to the third gas separation membrane stage. Non-permeates from the first and third gas separation stages are combined to produce a natural gas product. A permeate from the third gas separation membrane stage is combined with a non-permeate from the first gas separation membrane stage before it is compressed and fed to the second gas separation membrane stage.

In a first position, the handle is pivoted to allow the second end to be attached to the neck, thereby requiring the removal of a regulator, allowing the storage compartment to hold a regulator, protecting the neck from dust and other particulates and allowing a user to safely carry the cylinder. In a second position, the handle is pivoted to allow the second end form a strut, thereby providing the user a more stable operating position.

Abstract: A burner has a fuel/oxidant nozzles and a pair of dynamical lances spaced on either side thereof that inject a jet of fuel and primary oxidant along a fuel injection axis, and jets of secondary oxidant, respectively. Jets of actuating fluid impinge against the jets of secondary oxidant to fluidically angle the jets of secondary oxidant away from the fuel injection axis. The action of the angling away together with staging of the oxidant between primary and secondary oxidant injections allows achievement of distributed combustion conditions.
