Description
Gegenstand der Erfindung ist ein Verfahren zur Gewinnung eines Kohlenmonoxid- und eines Wasserstoffproduktes durch kryogene Zerlegung eines vorwiegend aus Wasserstoff (H2) und Kohlenmonoxid (CO) bestehenden Einsatzgases in einem zweistufigen Kondensationsprozess, wobei Spitzenkälte für die zweite Kondensationsstufe durch die Mischung einer H2-reichen Fraktion mit flüssigem Stickstoff (M-N2) erzeugt wird, sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a process for obtaining a carbon monoxide and a hydrogen product by cryogenic decomposition of a feed gas consisting predominantly of hydrogen (H 2 ) and carbon monoxide (CO) in a two-stage condensation process, wherein peak cooling for the second condensation stage by mixing an H 2 - rich fraction with liquid nitrogen (MN 2 ) is produced, and an apparatus for carrying out the method.
Durch unterschiedliche Erzeugungsmethoden, wie z. B. katalytische Dampfreformierung oder partielle Oxidation (POX), wird aus kohlenwasserstoffhaltigen Ausgangsstoffen, wie Erdgas, Flüssiggas, Naphta, Schweröl oder Kohle, sog. Synthesegas erzeugt, das zum größten Teil aus H2 und CO besteht, aber auch Methan (CH4), Wasser (H2O), Kohlendioxid (CO2) und andere Komponenten, wie z. B. Stickstoff und Argon enthält. Aus dem Synthesegas werden durch Reinigung und Zerlegung vor allem CO und H2 als Produkte gewonnen, die in der Industrie in vielfältiger Weise Verwendung finden.By different production methods, such. B. catalytic steam reforming or partial oxidation (POX), is produced from hydrocarbonaceous starting materials, such as natural gas, LPG, naphtha, heavy oil or coal, so-called synthesis gas, which for the most part consists of H 2 and CO, but also methane (CH 4 ) , Water (H 2 O), carbon dioxide (CO 2 ) and other components, such as. As nitrogen and argon contains. From the synthesis gas, CO and H 2 are obtained as products by purification and decomposition, which are used in industry in many ways.
Abhängig von der Zusammensetzung der zu trennenden Einsatzgase, dem geforderten Produktspektrum und der angestrebten Reinheit der Produkte, werden großtechnisch zur Synthesegastrennung vor allem zwei kryogene Trennverfahren, der Kondensationsprozess und die Methanwäsche, eingesetzt.Depending on the composition of the input gases to be separated, the required Product range and the intended purity of the products industrially for synthesis gas separation, especially two cryogenic separation processes, the condensation process and the methane wash used.
Der Kondensationsprozess, der ältere und einfachere der beiden kryogenen Trennverfahren, eignet sich besonders zur Trennung von Synthesegasen, die durch partielle Oxidation erzeugt werden, da derartige Gase für gewöhnlich mit einem hohen Druck vorliegen und gleichzeitig einen hohen CO- und einen niedrigen Methangehalt aufweisen. Beim Kondensationsprozess wird das Einsatzgas im indirekten Wärmetausch gegen anzuwärmende Verfahrensströme so weit abgekühlt, dass es zu einer Teilkondensation kommt, bei der sich eine CO-reiche, H2 enthaltende Flüssigfraktion und eine H2-reiche, CO enthaltende Gasfraktion bilden, die anschließend in einem Phasentrenner getrennt werden. Die CO-reiche Flüssigfraktion, in der noch H2 und andere Stoffe gelöst sind, wird nachfolgend gereinigt (H2-Strippung, Methanabtrennung) und als CO-Produkt abgegeben. Bei diesem Verfahren kann das im Einsatzgas enthaltene CO lediglich mit einer Ausbeute von ca. 90% gewonnen werden. Darüber hinaus fällt ein H2 enthaltender Stoffstrom an, der eine Reinheit von lediglich ca. 90mol-% aufweist, und daher nicht als Produkt abgegeben werden kann.The condensation process, the older and simpler of the two cryogenic separation processes, is particularly suitable for the separation of synthesis gases produced by partial oxidation, since such gases are usually of high pressure and at the same time have a high CO and a low methane content. During the condensation process, the feed gas is cooled in indirect heat exchange against process streams to be heated so far that it comes to a partial condensation in which form a CO-rich, H 2 -containing liquid fraction and an H 2 -rich, CO-containing gas fraction, which subsequently in a Phase separator to be separated. The CO-rich liquid fraction, in which H 2 and other substances are still dissolved, is subsequently purified (H 2 -stripping, methane separation) and released as CO product. In this method, the CO contained in the feed gas can only be obtained with a yield of about 90%. In addition, an H 2 -containing stream is obtained, which has a purity of only about 90 mol%, and therefore can not be discharged as a product.
Um die oben beschriebenen Nachteile zu umgehen, und ein CO-Produkt mit höherer Ausbeute zu gewinnen und/oder um ein H2-Produkt mit einer Reinheit von mehr als 95 mol-% zu erzeugen, wird nach dem Stand der Technik der Kondensationsprozess entweder um eine Membraneinheit oder um eine Kondensationsstufe erweitert (zweistufiger Kondensationsprozess). Bei beiden Prozessen wird die durch Kondensation gewonnene H2-reiche, CO enthaltende Gasfraktion einer weitern Behandlung unterzogen, wobei das Kohlenmonoxid weitgehend abgetrennt und in das CO-Produkt geführt wird; nach der Abtrennung des Kohlenmonoxids weist die H2-reiche Gasfraktion die erforderliche Reinheit von mehr als 95mol-% auf, wodurch in manchen Fällen auf eine Nachreinigung mittels Druckwechseladsorption verzichtet werden kann.In order to obviate the disadvantages described above and to obtain a CO product with higher yield and / or an H to produce 2 product with a purity of more than 95 mol%, the condensation process is according to the state of the art either a membrane unit or extended by a condensation stage (two-stage condensation process). In both processes, the H 2 -rich, CO-containing gas fraction obtained by condensation is subjected to a further treatment, wherein the carbon monoxide is largely separated and passed into the CO product; after the separation of the carbon monoxide, the H 2 -rich gas fraction has the required purity of more than 95 mol%, which can be dispensed in some cases on a post-purification by pressure swing adsorption.
Bei einem zweistufigen Kondensationsprozess wird die in der ersten Kondensationsstufe gewonnene H2-reiche, CO enthaltende Gasfraktion gegen anzuwärmende Verfahrensströme weiter abgekühlt, wobei eine zweite CO-reiche, H2 enthaltende Flüssigfraktion und eine zweite H2-reiche, CO enthaltende Gasfraktion entstehen, die anschließend in einem zweiten Phasentrenner getrennt werden. Die für die zweite Kondensationsstufe benötigte Spitzenkälte, wird nach dem Stand der Technik durch die Mischung von flüssigem Stickstoff mit einer vorwiegend aus Wasserstoff bestehenden Gasfraktion erzeugt, wozu flüssiger Stickstoff dem kryogenen Prozess von außen – z. B. von einem kryogenen Luftzerleger, in dem der für die POX benötigte Sauerstoff gewonnen wird – zugeführt wird. Um am zweiten Abscheider eine ausreichend tiefe Temperatur zu erreichen, muss dem zweistufigen Kondensationsprozess eine relativ große Menge an flüssigem Stickstoff zugeführt werden, mit der eine größere, als zur Deckung der Kältebilanz des Prozesses benötigte Kältemenge eingebracht wird. Die überschüssige Kältemenge geht bisher ungenutzt verloren. Da der flüssige Stickstoff mit beträchtlichem apparativem und vor allem energetischem Aufwand hergestellt wird, beeinträchtigt die ungenutzte Kältemenge die Wirtschaftlichkeit eines zweistufigen Kondensationsprozesses erheblich.In a two-stage condensation process, the H 2 -rich, CO-containing gas fraction obtained in the first condensation stage is further cooled against zuheizmende process streams to form a second CO-rich, H 2 -containing liquid fraction and a second H 2 -rich, CO-containing gas fraction, the subsequently separated in a second phase separator. The peak cold needed for the second condensation stage is generated in the prior art by the mixture of liquid nitrogen with a predominantly hydrogen gas fraction, including liquid nitrogen from the cryogenic process from the outside -. B. from a cryogenic air separation, in which the oxygen required for the POX is obtained - is supplied. In order to achieve a sufficiently low temperature at the second separator, a relatively large amount of liquid nitrogen must be supplied to the two-stage condensation process, with which a greater amount of refrigerant than is required to cover the cold balance of the process is introduced. The excess amount of cold is lost so far unused. Since the liquid nitrogen is produced with considerable equipment and above all energy expenditure, the unused amount of cold significantly affects the economy of a two-stage condensation process.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art sowie eine Vorrichtung zur Durchführung des Verfahrens anzugeben, die es ermöglichen, mit geringeren Betriebskosten, als es nach dem Stand der Technik möglich ist, aus einem Synthesegas ein Wasserstoff- und ein Kohlenmonoxidprodukt zu erzeugen.Of the Invention is therefore the object of a method of the initially and a device for carrying out the method, which make it possible with lower operating costs than is possible in the prior art, from a synthesis gas, a hydrogen and a carbon monoxide product to create.
Diese Aufgabe wird verfahrensseitig erfindungsgemäß dadurch gelöst, dass zumindest ein Teil (G-N2) des M-N2 aus gasförmig dem zweistufigen Kondensationsprozess von außen zugeführtem Stickstoff durch Abkühlung, Kondensation und, vorzugsweise, Unterkühlung gegen anzuwärmende Verfahrensströme innerhalb des zweistufigen Kondensationsprozesses erzeugt wird.This object is achieved procedurally according to the invention in that at least a part (GN 2 ) of the MN 2 from the two-stage condensation process externally supplied nitrogen by cooling, condensation and, preferably, subcooling against process streams to be heated within the two-stage condensates sationsprozesses is generated.
Der Erfindung liegt der Erfahrung zugrunde, dass gasförmiger Stickstoff im Vergleich zu flüssigem Stickstoff wesentlich kostengünstiger produziert werden kann. Durch die Anwendung des erfindungsgemäßen Verfahrens werden somit entsprechende Reduzierungen der Betriebs-, aber auch der Investitionskosten im Bereich des Luftzerlegers, erreicht.Of the Invention is based on the experience that gaseous nitrogen compared to liquid nitrogen much cheaper can be produced. By the application of the method according to the invention Thus, corresponding reductions in operating, but also the investment costs in the air separator.
Dient der zweistufige Kondensationsprozess beispielsweise zur Zerlegung von Synthesegas, das durch partielle Oxidation (POX) erzeugt wird, und wird der für die POX benötigte Sauerstoff in einem Luftzerleger durch die kryogene Zerlegung von Luft gewonnen, so wird der flüssige Stickstoff zweckmäßiger Weise von diesem Luftzerleger bezogen.serves the two-stage condensation process, for example, for decomposition of synthesis gas produced by partial oxidation (POX) and becomes the for the POX needed Oxygen in an air separator due to the cryogenic decomposition of Gained air, so does the liquid Nitrogen expedient manner sourced from this air separator.
Zeigt die Kältebilanz, dass im zweistufigen Kondensationsprozess nicht genügend G-N2 erzeugt werden kann, um die gewünschte Temperatur am Abscheider in der zweiten Kondensationsstufe zu erreichen, so sieht eine Ausgestaltung des erfindungsgemäßen Verfahrens vor, dass die fehlende Stickstoffmenge (L-N2) flüssig von außen zugeführt wird. Das Mengenverhältnis von G-N2 zu L-N2 wird zweckmäßiger Weise so eingestellt, dass sowohl das Kohlenmonoxidprodukt mit der gewünschten Ausbeute als auch das Wasserstoffprodukt mit der geforderten Reinheit, jedoch ohne Kälteüberschuss erzeugt werden.If the cold balance shows that sufficient GN 2 can not be produced in the two-stage condensation process in order to achieve the desired temperature at the separator in the second condensation stage, an embodiment of the method according to the invention provides that the missing amount of nitrogen (LN 2 ) is supplied liquid from the outside becomes. The quantitative ratio of GN 2 to LN 2 is expediently adjusted so that both the carbon monoxide product with the desired yield and the hydrogen product with the required purity, but without a cold excess, are produced.
Das erfindungsgemäße Verfahren weiterbildend, wird vorgeschlagen, dass G-N2 oder/und L-N2 von einem Luftzerleger bezogen werden, in dem Sauerstoff zur Erzeugung des Wasserstoff Kohlenmonoxid enthaltenden Einsatzgases (beispielsweise in einer POX) produziert wird. Vorzugsweise wird G-N2 mit mittlerem oder niedrigem Druckniveau aus dem Luftzerleger abgezogen, um den Gesamtenergiebedarf des Prozesses zu minimieren.Further developing the process according to the invention, it is proposed that GN 2 or / and LN 2 be obtained from an air fractioner in which oxygen is produced (for example in a POX) to produce the feed gas containing hydrogen carbon monoxide. Preferably, medium or low pressure level GN 2 is withdrawn from the air separator to minimize the overall energy requirements of the process.
Die Erfindung betrifft ferner eine Vorrichtung zur Durchführung eines zweistufigen Kondensationsprozesses (Gaszerleger), in der ein vorwiegend aus Wasserstoff (H2) und Kohlenmonoxid (CO) bestehendes Einsatzgas in ein Kohlenmonoxid- und ein Wasserstoffprodukt zerlegbar ist, wobei Spitzenkälte für die zweite Kondensationsstufe des Gaszerlegers durch die Mischung einer H2-reichen Fraktion mit flüssigem Stickstoff (M-N2) erzeugbar ist.The invention further relates to an apparatus for carrying out a two-stage condensation process (gas decomposer) in which a feed gas consisting predominantly of hydrogen (H 2 ) and carbon monoxide (CO) can be decomposed into a carbon monoxide and a hydrogen product, wherein peak cooling for the second condensation stage of the gas decomposer by the mixture of an H 2 -rich fraction with liquid nitrogen (MN 2 ) is generated.
Vorrichtungsseitig wird die gestellte Aufgabe erfindungsgemäß dadurch gelöst, dass der Gaszerleger eine Einrichtung zur Herstellung von zumindest eines Teils (G-N2) des M-N2 umfasst, in welcher gasförmig von außen zuführbarer Stickstoff durch Abkühlung gegen anzuwärmende Verfahrensströme kondensierbar und, vorzugsweise, unterkühlbar ist.On the device side, this object is achieved according to the invention in that the gas decomposer comprises a device for producing at least part (GN 2 ) of the MN 2 , in which nitrogen which can be supplied in gaseous form from the outside by cooling against process streams to be heated is condensable and, preferably, subcoolable.

Zweckmäßiger Weise ist die warme Seite des ersten Wärmetauschers über eine Leitung mit einer Quelle für gasförmigen Stickstoff verbunden, über die Stickstoff gasförmig dem ersten Wärmetauscher zuführbar ist. In den Wärmetauschern erfolgt anschließend gegen anzuwärmende Verfahrensströme eine Abkühlung, Kondensation und gegebenenfalls eine Unterkühlung des Stickstoffs.To The prior art, a gas separator usually two in series switched heat exchanger on, where it is at the heat exchangers Plate heat exchanger act and the cold side of the first heat exchanger is warmer as the warm side of the second heat exchanger. Appropriate way is the warm side of the first heat exchanger over one Line with a source of gaseous nitrogen connected, over the nitrogen gaseous the first heat exchanger supplied is. In the heat exchangers takes place afterwards against warming process streams a cooling, condensation and optionally a supercooling of Nitrogen.
Für den Fall, dass innerhalb des Gaszerlegers nicht genügend Kälte zur Verfügung steht, um die gesamte Menge des benötigten M-N2 aus gasförmigem Stickstoff zu erzeugen, sieht eine Ausgestaltung der erfindungsgemäßen Vorrichtung vor, dass der Gaszerleger mit einer Einrichtung ausgerüstet ist, über die eine Teilmenge des M-N2 als flüssiger Stickstoff (L-N2) von außerhalb dem Gaszerleger zuführbar ist.In the event that not enough cold is available within the Gaszerlegers to produce the entire amount of the required MN 2 of gaseous nitrogen, provides an embodiment of the device according to the invention that the gas separator is equipped with a device on a subset of the MN 2 as liquid nitrogen (LN 2 ) from outside the gas separator can be fed.
Eine bevorzugte Ausgestaltung der erfindungsgemäßen Vorrichtung sieht vor, dass der gasförmige Stickstoff zur Erzeugung von G-N2 oder/und L-N2 von einem Luftzerleger beziehbar sind, in dem Sauerstoff zur Erzeugung des Wasserstoff und Kohlenmonoxid enthaltenden Einsatzgases (beispielsweise in einer POX) produziert wird. Vorzugsweise besitzt dieser gasförmige Stickstoff aus dem Luftzerleger ein mittleres oder niedriges Druckniveau.A preferred embodiment of the device according to the invention provides that the gaseous nitrogen for the production of GN 2 or / and LN 2 are obtainable from an air separator, is produced in the oxygen for generating the feed gas containing hydrogen and carbon monoxide (for example in a POX).
