摘要:
Die Erfindung betrifft ein Verfahren (100) zur Gewinnung von Krypton und/oder Xenon aus einem krypton- und/oder xenonhaltigen Rohgemisch (F), das in einem überwiegenden Anteil Sauerstoff und zudem wenigstens ein weiteres Nichtedelgas aufweist, wobei das Verfahren die Schritte umfasst, das Rohgemisch (F) vorzukühlen (3), aus dem vorgekühlten Rohgemisch (F) zumindest einen Teil des Sauerstoffs (GOX) in einem ersten Tieftemperaturrektifikationsschritt abzutrennen (1) und damit ein krypton- und/oder xenonreiches Konzentrat zu erhalten (c), aus dem Konzentrat in einem zweiten Tieftemperaturrektifikationsschritt (2) eine kryptonreiche Fraktion und/oder eine xenonreiche Fraktion zu separieren (k,f) und aus der kryptonreichen Fraktion (k) und/oder der xenonreichen Fraktion (f)anschließend, vorzugsweise mittels wenigstens eines Getters (5, 8), bei dem ersten Tieftemperaturrektifikationsschritt nicht abgetrennten Sauerstoff und das wenigstens eine weitere Nichtedelgas zumindest zu einem Teil zu entfernen. Eine zur Durchführung des Verfahrens (90) eingerichtete Vorrichtung ist ebenfalls Gegenstand der Erfindung.
摘要:
The invention relates to the use of biomethanol from the pulp industry in the production of biohydrogen. The preferred biomethanol comprises purified biomethanol derived from black liquor. The invention also relates to a process for the production of biohydrogen from crude biomethanol recovered from black liquor and to a process for producing hydrocarbon biofuel using such biohydrogen as a hydrogen source. The invention further relates to a biofuel production facility for producing fuel from biohydrogen and biohydrocarbon, and to biofuel so produced. The invention makes it possible to produce a biofuel, wherein 100% of the raw material stems from non-fossil sources.
摘要:
A current collector structure that is used to distribute an electrical potential to an electrode layer of an electrochemical cell. The electrochemical cell has an electrolyte layer adjacent the electrode layer for transport of oxygen ions. The current collector structure has a porous, electrically conductive layer located on the electrode layer. Additionally, at least one elongated strip-like layer formed of an electrically conductive material is located on the porous, electrically conductive layer, opposite the electrode and oriented in a lengthwise direction of the electrode layer.

An oxygen generating device includes a housing, an inlet formed in the housing, a compressor, and a sieve module. The device further includes a self-serviceable filter disposed between the compressor and the sieve module. The method for generating an oxygen-enriched gas includes introducing a feed gas into the oxygen generating device via the inlet, compressing the feed gas via the compressor, filtering the compressed feed gas by removing at least one contaminant from the feed gas via the self-serviceable filter, introducing the filtered feed gas into the sieve module, and generating the oxygen-enriched gas from the filtered feed gas.
摘要:
The invention relates to a method for producing hydrogen and power from a synthesis gas (4) that contains CO, H2 and H2S. The synthesis gas is separated into two partial streams (9, 27), vapor (11) is added to the first partial stream of synthesis gas, out a CO conversion (13) is carried out at a temperature of 220 °C to 500 °C, pure hydrogen (16) is obtained from the converted synthesis gas in a pressure swing absorption device (15) and a residual PSA gas (18) is produced. The second partial stream of synthesis gas is fed to a power-generating gas turbine for combustion, H2S and optionally other sulfur-containing components are removed in one or more separators that are arranged in any position in the process, however, before entry into the gas turbine, the residual PSA gas is mixed with nitrogen (20), the gas mixture so obtained is compressed and the compressed gas mixture is admixed to the partial stream of synthesis gas that is fed to the power-generating gas turbine (32).
摘要:
A system for providing industrial gas to a use point in relatively small quantities that would otherwise require the use of high pressure gas cylinders, wherein industrial gas (4) is generated (30) from a feed (1), liquefied using refrigeration generated by a refrigeration system (34), and stored in a storage vessel (33) prior to provision to the use point (7). The preferred refrigeration system is a pulse tube system powered by gas associated with the industrial gas generation system.
