Abstract: A combined plant for cryogenic separation and liquefaction of methane and carbon dioxide in a biogas stream, including a mixing means, a compressor, a first exchanger, a distillation column, a second exchanger, a separating means, an expanding means, and a separator vessel. Wherein, the mixing means is configured such that the recycle gas is the overhead vapour stream, and the first exchanger and the expanding means are combined.

Abstract: The invention relates to a method and facility for manufacturing a cross-linked fiberglass material, in which melted glass is produced in a melting furnace heated via combustion of a fuel with an oxygen-rich oxidant. The melted glass is converted into glass filaments, the filaments are bonded, a sheet is made from the bonded filaments, and the sheet is then cross-linked. The fumes from the melting furnace are used to preheat a combustion reagent in two steps: a first step in which air is heated via heat exchange with the fumes, and a second step in which the combustion reagent is preheated via heat exchange with the hot air. The air is then used in the cross-linking step of the method for converting the melted glass into a fiberglass material.

Abstract: The present invention is a method of reducing the carbon dioxide balance from a reformer furnace flue gas to the high pressure syngas exit water gas shift reaction unit. Introducing a heated gas mixture into at least one pre-reforming chamber. The heating being provided by indirect heat exchange with one or more of an SMR furnace flue gas or an SMR furnace syngas introducing the gas mixture into a standard H2 PSA unit, wherein the gas mixture is separated into a hydrogen enriched stream and a PSA tail gas stream; introducing the PSA tail gas stream into a CPU system, wherein the PSA tail gas stream is separated into a carbon dioxide enriched stream, a hydrogen rich stream, and a residual stream, and introducing the residual stream as fuel into the reformer furnace along with natural gas.

Abstract: A burner assembly having improved flame length and shape control is presented, which includes in exemplary embodiments at least one fuel fluid inlet and at least one oxidant fluid inlet, means for transporting the fuel fluid from the fuel inlet to a plurality of fuel outlets-, the fuel fluid leaving the fuel outlets in fuel streams that are injected into a combustion chamber, means for transporting the oxidant fluid from the oxidant inlets to at least one oxidant outlet, the oxidant fluid leaving the oxidant outlets in oxidant fluid streams that are injected into the combustion chamber, with the fuel and oxidant outlets being physically separated, and geometrically arranged in order to impart to the fuel fluid streams and the oxidant fluid streams angles and velocities that allow combustion of the fuel fluid with the oxidant in a stable, wide, and luminous flame. Alternatively, injectors may be used alone or with the refractory block to inject oxidant and fuel gases.

Abstract: Process for melting a metal charge in a rotary furnace equipped with at least one oxygen burner, comprising the steps of:(i) adding between 1.5 and 9% of a charge of solid fuel to the metal charge to form a combined charge; and(ii) injecting at least one jet of oxygen in a direction of the combined charge in the furnace.

Abstract: Method of reliquefying gaseous helium produced when transferring liquid helium from a donor container (R1) to a receiver container (R2), characterized in that a stream of gaseous helium is bled off from a point in a compression unit (10) intended for charging with gaseous helium under pressure, this stream of gaseous helium is cooled by heat exchange with the gaseous helium intended for the compression unit (10) and the compressed gaseous helium thus cooled is expanded in order to obtain reliquefied helium.
