Description
Die Erfindung richtet sich auf ein Verfahren zur Erzeugung von Synthesegas für eine Ammoniakanlage.The The invention is directed to a process for producing synthesis gas for one Ammonia plant.
Zur Herstellung von Synthesegas für unterschiedliche Verwendungszwecke gibt es eine Reihe von Lösungsmöglichkeiten, etwa für Methanol oder die Fischer-Tropsch-Synthese, wobei dabei auch bekannt ist, den benötigten Sauerstoff mittels einer Sauerstofftransportmembran in einem Membranreaktor einem Luftstrom zu entziehen, wobei es sich dabei um eine gemischte sauerstoffionen- und elektronenleitende Membraneinheit handelt.to Production of synthesis gas for different uses, there are a number of possible solutions, about for Methanol or the Fischer-Tropsch synthesis, whereby also known is, the needed Oxygen by means of an oxygen transport membrane in a membrane reactor to escape a stream of air, which is a mixed one oxygen ion and electron conducting membrane unit.
Hier setzt die Erfindung an, deren Aufgabe darin besteht, einen derartigen Membranreaktor für die Erzeugung von Synthesegas für eine Ammoniakanlage zu nutzen.Here applies the invention whose object is to provide such Membrane reactor for the Generation of synthesis gas for to use an ammonia plant.
Zur Lösung dieser Aufgabe schlägt daher die Erfindung vor, daß in einem Membranreaktor aus einem Luftstrom über eine Sauerstoff-Transportmembran der Sauerstoff entzogen wird, der gewonnene Sauerstoff direkt zur partiellen Oxidation von Kohlenwasserstoffen, z.B. Erdgas, in Gegenwart eines Steam-Reformung-Katalysators herangezogen und dem reformierten Synthesegas in einem Sekundärreformer nach der par tiellen Oxidation ein weiterer Stickstoff enthaltender Strom zugegeben wird, um das für eine Ammoniaksynthesegas-Zusammensetzung erforderliche Verhältnis von Stickstoff und Wasserstoff einzustellen.to solution this task strikes Therefore, the invention provides that in a membrane reactor from an air stream over an oxygen transport membrane the oxygen is extracted, the recovered oxygen directly to partial oxidation of hydrocarbons, e.g. Natural gas, in the presence a steam reforming catalyst used and the reformed Synthesis gas in a secondary reformer after par tial oxidation another nitrogen-containing Electricity is added to that for an ammonia synthesis gas composition required ratio of nitrogen and hydrogen.
Grundsätzlich ist für sich gesehen die Entnahme von Sauer-stoff in einer derartigen Membran z.B. in der EP-1 007 473 beschrieben, wobei dort der Sauerstoff von einem Sweep-Gas (= Trägergas für das übertragene O2) ausgetragen wird und die für die Funktion der Sauerstoff-Transportmembran erforderliche Aufheizung durch direkte Verbrennung von Heizmittel in Luft vorgenommen wird. Dabei ist dort eine anschließende Partialoxidation in einem autothermen Reformer (ATR) vorgesehen.In principle, the removal of oxygen in such a membrane is described, for example, in EP-1 007 473, where the oxygen is discharged from a sweep gas (= carrier gas for the transferred O 2 ) and for the function the oxygen transport membrane required heating by direct combustion of heating medium in air is made. Here, a subsequent partial oxidation in an autothermal reformer (ATR) is provided.
Hier beschreitet die vorliegende Erfindung einen oben angegebenen, anderen Weg. In der EP-1 370 485 ist noch ein unterstöchiometrisches H2/N2-Synthesegasverfahren beschrieben, wobei die US-5,820,654 ein Verfahren zur Synthesegaserzeugung durch partielle Oxidation unter Erzeugung eines N2-reichen Stromes beschreibt.Here, the present invention proceeds in a different way as stated above. EP-1 370 485 still describes a substoichiometric H 2 / N 2 synthesis gas process, US Pat. No. 5,820,654 describing a process for producing synthesis gas by partial oxidation to generate an N 2 -rich stream.
Grundsätzlich ist es nach der Erfindung möglich, über den Membranreaktor eine praktisch 100 %-ige Trennung von O2 und N2 vorzunehmen. Dies ist aber nicht zwingend notwendig. So sieht die Erfindung in Ausgestaltung vor, daß ein Stick stoff- und 1 bis 21 % O2-enthaltender Gasstrom zur Einstellung des für eine Ammoniaksynthesegas-Zusammensetzung erforderlichen Verhältnisses dem Sekundärreformer zugeführt wird.In principle, it is possible according to the invention to carry out a virtually 100% separation of O 2 and N 2 via the membrane reactor. But this is not absolutely necessary. Thus, the invention provides in an embodiment that a nitrogen material and 1 to 21% O 2 -containing gas stream for adjusting the required for a Ammoniaksynthesegas composition ratio is supplied to the secondary reformer.
Je nach zu treibendem Aufwand und einzusetzenden Anlageelementen kann der Druck des Sauerstoff liefernden Gases (z.B. Luft) zwischen 1 bis 100 bar, bevorzugt zwischen 1 und 50 bar, liegen, wie dies in Ausgestaltung nach der Erfindung ebenfalls vorgesehen ist. Üblicherweise wird aus energetischen Gründen ein möglichst geringer Druck der Luft z.B. von ca. 2 bar eingesetzt.ever can be driven to expenditure and system elements to be used the pressure of the oxygen supplying gas (e.g., air) is between 1 to 100 bar, preferably between 1 and 50 bar lie, as in the embodiment is also provided according to the invention. Usually becomes energetic establish one possible low pressure of the air e.g. used by about 2 bar.
In einer anderen Ausgestaltung des Verfahrens kann dabei der Druck des Sauerstoff liefernden Gases mindestens 2 bis 10 bar über dem Druck des Synthesegases liegen. Liefert die Anlage einen nicht für den Prozeß benötigten Luftstrom, so kann dieser zweckmäßig über eine Entspannungsturbine, die mit dem Verdichter gekoppelt ist, geleitet werden. Auch dies ist in Ausgestaltung nach der Erfindung vorgesehen.In another embodiment of the method may be the pressure the oxygen supplying gas at least 2 to 10 bar above the Pressure of the synthesis gas lie. Does the system deliver a stream of air that is not required for the process, so this can be useful over a Relaxation turbine, which is coupled to the compressor, passed become. This is also provided in an embodiment according to the invention.
Vorteilhaft ist es auch, wenn zur Erzielung höherer Temperaturen im Synthesegas der in der Sauerstoff abgereicherten Abluft verbliebene Sauerstoff zur partiellen Oxidation und zur Spaltung der restlichen Kohlenwasserstoffe zu CO und H2 im Sekundärreformer herangezogen wird, wobei es zweckmäßig sein kann, wenn der Restluftsauerstoffanteil im Luftstrom hinter dem Membranreaktor mit der Transportmembran 1 bis 10% O2 beträgt .It is also advantageous if the oxygen remaining in the oxygen-depleted exhaust air is used for partial oxidation and for cleaving the remaining hydrocarbons to CO and H 2 in the secondary reformer to achieve higher temperatures in the synthesis gas, it may be useful if the residual oxygen content in the air stream behind the membrane reactor with the transport membrane 1 to 10% O 2 .
In weiterer Ausgestaltung ist vorgesehen, daß der Restluftsauerstoffanteil zur Erzielung der Austrittstemperatur am Sekundärreformer von 1.000 bis 1.100°C so eingestellt wird, daß das Verhältnis (H2 + CO) : N2 im Gas am Austritt ca. 3 entspricht.In a further embodiment, it is provided that the residual oxygen content to achieve the outlet temperature at the secondary reformer of 1,000 to 1,100 ° C is set so that the ratio (H 2 + CO): N 2 in the gas at the outlet corresponds to about 3.
In einer weiteren Ausgestaltung kann vorgesehen sein, daß im Membranreaktor die partielle Oxidation (POX-Reaktion) und die Steam-Reforming-Reaktion z.B. über die Katalysatormenge und/oder die Kalysatoraktivität auf der einen Seite und die Gasströme und Membranflächen auf der anderen Seite thermisch derart gekoppelt sind, daß der Sauerstofftransport bei sinkender Temperatur nicht verlöscht und bei steigender Temperatur den selbstverstärkenden Effekt des steigenden Sauerstoffstromes an der Sauerstoff-Transportmembran begrenzt, wobei die entsprechenden Oberflächen hierzu mit einer Katalysator- und/oder Schutzschicht bzw. einer extra Katalysatorschüttung davor ausgerüstet sind.In a further embodiment may be provided that in the membrane reactor the partial oxidation (POX reaction) and the steam reforming reaction e.g. above the amount of catalyst and / or the Kalysatoraktivität on the one side and the gas streams and membrane surfaces on the other hand are thermally coupled such that the oxygen transport does not extinguish when the temperature drops and as the temperature rises the self-reinforcing Effect of increasing oxygen flow on the oxygen transport membrane limited, the corresponding surfaces with a catalyst and / or protective layer or an extra catalyst bed before equipped are.
