Abstract
(DE)
Die Erfindung betrifft ein Verfahren sowie eine Vorrichtung zur Erzeugung eines wasserstoffhaltigen Gasprodukts in einer ersten (7) oder einer, einen geringeren Wasserstoffgehalt als die erste aufweisenden zweiten Modifikation (14), wobei ein Wasserdampf, Kohlenmonoxid und Wasserstoff enthaltendes und mit einem Wasserdampf/Kohlenmonoxid-Verhältnis (D/CO-Verhältnis) zwischen 1,8 und 2,5 mol/mol bereitgestelltes Synthesegas (1) mit Hilfe eines Shift-Konverters (S) behandelt wird, um ein Zwischenprodukt (3, 12) zu erhalten, aus dem jeweils Wasser und Sauergase zur Gewinnung des wasserstoffhaltigen Gasprodukts (7, 14) abgetrennt werden. Kennzeichnend hierbei ist, dass das Synthesegas (2) dem Shift-Konverter (S) in der bereitgestellten Form zugeführt wird, um das Gasprodukt in der ersten Modifikation (7) zu erhalten, während das Verhältnis von Wasserdampf zu Kohlenmonoxid im Synthesegas (11) durch die Abtrennung von Wasser stromaufwärts des Shift-Konverters (S) auf einen Wert zwischen 0,1 und 0,6 mol/mol eingestellt wird, um das Gasprodukt in der zweiten Modifikation (14) zu gewinnen.
(EN)
The invention relates to a process and to an apparatus for producing a hydrogen-containing gas product in a first modification (7) or a second modification (14) having a lower hydrogen content than the first modification, wherein a synthesis gas (1) containing steam, carbon monoxide and hydrogen and provided with a steam/carbon monoxide ratio (S/CO ratio) between 1.8 and 2.5 mol/mol is treated using a shift converter (S) to obtain an intermediate product (3, 12) from which water and acid gases are separated in each case to obtain the hydrogen-containing gas product (7, 14). The characteristic feature here is that the synthesis gas (2) is supplied to the shift converter (S) in the form in which it is provided to obtain the gas product in the first modification (7), while the ratio of steam to carbon monoxide in the synthesis gas (11) is adjusted to a value between 0.1 and 0.6 mol/mol by the removal of water upstream of the shift converter (S) to obtain the gas product in the second modification (14).
(FR)
L’invention concerne un procédé ainsi qu’un dispositif pour la génération d’un produit gazeux contenant de l'hydrogène dans une première (7) ou dans une deuxième modification (14) présentant une teneur en hydrogène plus faible que la première, un gaz de synthèse (1), contenant de la vapeur d’eau, du monoxyde de carbone et de l‘hydrogène et ayant un rapport vapeur d’eau / monoxyde de carbone (rapport D/CO) compris entre 1,8 et 2,5 mol/mol, étant traité au moyen d’un convertisseur catalytique (S), pour obtenir un produit intermédiaire (3, 12), duquel l’eau et les gaz acides sont séparés pour obtenir le produit gazeux contenant de l'hydrogène (7, 14). L’invention est caractérisée en ce que le gaz de synthèse (2) est introduit dans le convertisseur catalytique (S) dans la forme fournie, pour obtenir le produit gazeux dans la première modification (7), tandis que le rapport de vapeur d’eau au monoxyde de carbone dans le gaz de synthèse (11) est réglé par la séparation d’eau en amont du convertisseur catalytique (S) à une valeur comprise entre 0,1 et 0,6 mol/mol, pour obtenir le produit gazeux dans la deuxième modification (14).
