摘要： Das Verfahren und die Vorrichtung dienen zur Gewinnung von wasserstofffreiem Stickstoff durch Tieftemperaturzerlegung von Luft. Wasserstoffhaltige Luft wird als Einsatzluftstrom (1) von einem Luftverdichter (2) angesaugt und verdichtet. Der verdichtete Einsatzluftstrom (4) wird in eine katalytische Reinigungseinheit (5) eingeleitet. In der katalytischen Reinigungseinheit (5) werden Kohlenmonoxid und Wasserstoff aus dem Einsatzluftstrom (4) entfernt. Aus der katalytischen Reinigungseinheit (5) wird ein gereinigter Einsatzluftstrom (6) entnommen. Der gereinigte Einsatzluftstrom (6) wird abgekühlt (7) und in eine Trennsäule (10) eingeleitet (8). Die Trennsäule (10) weist unmittelbar unterhalb ihres Kopfes einen Sperr-Stoffaustauschabschnitt (15) im Umfang von ein bis vier theoretischen beziehungsweise ein bis sechs praktischen Böden auf. Von einer Zwischenstelle der Trennsäule (10), die unmittelbar unterhalb des Sperr-Stoffaustauschabschnitts (15) angeordnet ist, wird ein wasserstofffreier Stickstoffstrom (16, 17) entnommen und als wasserstofffreies Stickstoffprodukt gewonnen. Die katalytische Reinigungseinheit (5) wird bei einer Temperatur von weniger als 50°C betrieben. Die katalytische Reinigungseinheit (5) enthält Hopcalit als einziges katalytisch aktives Material.

摘要： Carbon monoxide (CO) may be removed from flue gas generated by oxyfuel combustion of a hydrocarbon or carbonaceous fuel, by contacting the flue gas, or a CO-containing gas derived therefrom, at a first elevated temperature, e.g. at least 80°C, and at a first elevated pressure, e.g. at least 2 bar (0.2 MPa), with at least one catalyst bed comprising a CO-oxidation catalyst in the presence of oxygen (O 2 ) to convert CO to carbon dioxide and produce carbon dioxide-enriched gas. The carbon dioxide produced from the CO may be recovered from the carbon dioxide-enriched gas using conventional carbon dioxide recovery techniques. NO in the flue gas may also be oxidized to nitrogen dioxide (NO 2 ) and removed using conventional NO 2 removal techniques, or may be reduced in the presence of a reducing gas to nitrogen (N 2 ) which does not have to be removed from the gas.

摘要： A process for recovering hydrogen from a multi-component gas stream is provided. This process includes compressing said multi-component gas stream, thereby creating a compressed multi-component gas stream. This process includes heating the compressed multi-component gas stream, thereby creating a heated compressed multi-component gas stream. This process also includes introducing stream into the heated compressed multi-component gas stream, thereby creating a first feed stream. This process further includes introducing the first feed stream into a CO shift conversion process, thereby creating a first intermediate stream. This process also includes introducing the first intermediate stream into an amine wash process, thereby creating a second intermediate stream and a carbon dioxide stream. This process also includes introducing the second intermediate stream into a methanation process, thereby creating a third intermediate stream. This process also includes introducing the third intermediate stream into an adsorbent bed to remove moisture, thereby creating a fourth intermediate dry stream. This process also includes introducing the fourth intermediate stream into a cryogenic distillation process, thereby creating a hydrogen stream, a nitrogen stream, and a waste stream.

摘要： The invention relates to an air distillation method that employs at least two dual distillation columns (6A, 6B) and at least two argon columns (14A, 14B) which operate in parallel in order to distil air by forming at least two argon-enriched fluids (Ar/N/O). The argon-enriched fluids are mixed downstream from the argon columns and are subsequently compressed in a common compressor (42). The compressed fluids are then made to react in a common deoxygenation unit (46) in order to deoxygenate said fluids, thereby producing water. The fluids are then passed into at least one common drying unit (50). The deoxygenated and dried fluids are distilled in at least one denitrogenation column (18A, 18B) in order to form argon and a second nitrogen-enriched fluid.
