摘要:
The invention relates to a device for the reactive conversion of gaseous streams at high temperatures in excess of 1000° C. Said device comprises a reaction chamber (8) with an inlet opening for the gaseous streams to be converted, in particular a burner head (2) and an outlet opening for the converted gaseous streams. In order to guarantee the highest possible conversion performance, the reaction chamber (8) has a narrow construction, extending longitudinally from the inlet opening to the outlet opening to form a controlled gaseous flow, thus preventing a circulatory flow in the reaction chamber (8). To achieve reaction conditions that are as adiabatic as possible, the reaction chamber (8) is thermally insulated with a layer (7) that has a porous foam and/or fiber structure. In the simplest embodiment, the reaction chamber (8) is cylindrical, thus achieving a tubular flow reactor construction for the entire device.

The invention relates to a burner with a burner head (1) and a gas feed pipe (2) that is located in the burner head (1) and that is surrounded by an ring channel (3) for feed of another gas. In the gas feed pipe (2) and in the ring channel (3), there are means (10, 11) for producing a swirl of the gas flowing through the gas feed pipe (2) and that flowing through the ring channel (3).

The invention relates to a process for recovering argon by low-temperature separation of air. Rectifying system (2, 4) exhibits at least one air separation column (4), which has a partition (5) that runs in lengthwise direction of the column, by which air separation column (4) is separated at the level of partition (5) into a first subsection and a second subsection (6, 7). A fluid (3) that contains oxygen and argon is introduced into first subsection (6). A stream (13) that contains oxygen and argon with an argon concentration of between 15% and 50% is removed in second subsection (7).
摘要:
A furnace for steam reforming a feed stream containing hydrocarbon, preferably methane, having: a combustion chamber, a plurality of reactor tubes arranged in the combustion chamber for accommodating a catalyst and for passing the feed stream through the reactor tubes, and at least one burner which is configured to burn a combustion fuel in the combustion chamber to heat the reactor tubes. In addition at least one voltage source is provided which is connected to the plurality of reactor tubes in such a manner that in each case an electric current which heats the reactor tubes to heat the feedstock is generable in the reactor tubes.

摘要:
A process and system for the generation of synthesis gas that is provided, in particular, for preparing hydrocarbon-containing fuel, ammonia or urea. The process follows the steps of providing a first feed gas stream of methane and reacting the first feed gas stream with steam in a reforming step, obtaining a synthesis gas stream of CO and H2. It is further provided that at least one first substream is separated off from the feed gas stream before the reforming step, the first substream is then burnt with a second feed gas stream of at least 95% by volume oxygen to give an exhaust gas stream comprising CO2 and water, and at least one part of the exhaust gas stream is recirculated to the feed gas stream after the first substream is separated off.

摘要:
A process for generating a syngas from a CO2-rich and hydrocarbon-containing feed gas, wherein a CO2-rich and hydrocarbon-containing feed gas is provided and is reacted in a syngas generation step by means of partial oxidation or steam reforming to give an H2- and CO-comprising syngas. At least CO2 is removed from the feed gas in a scrubbing of the feed gas by means of a scrubbing medium, before the feed gas is fed to the syngas generation step.

The invention relates to a process and an apparatus for producing a profiled sheet, in which the sheet is provided with a corrugation which runs obliquely with respect to the edges of the sheet and has a substantially constant angle of inclination. At least one edge region of the sheet is deformed by means of a ram-like deformation tool (6) which is alternately brought into contact with the edge region and removed from the edge region.
摘要:
A system for enhanced oil recovery from an oil field that uses the associated gases collected to produce synthetic crude oil from a GTL plant. The pressure in the oil field is maintained by injecting nitrogen obtained from an ASU. The ASU is powered by an associated power plant that uses oxygen produced by the ASU and the Fisher Tropsch tail gases (hydrogen and steam) of the GTL plant. Nitrogen recovered from the tail gas of the power plant boosts the available nitrogen needed for the enhanced oil recovery operation.
