ohne Entspannung durch einen Kühler, so Usst sich leicht erreichen, dass Abscheidung von flüssigem bezw. festem StickatoStetraoxyd erfolgt, ohne dass Kohlensäure mit abgeschieden würde. Auch kann man direkt konzentrierte Salpetersäure darstellen, indem man Wasserdampf oder Wasserstoff oder wasserstofthältige Brennstoffe den zur Verbrennung bestimmten Go sen (dem Kohlenoxyd bezw. der Luft oder dem Luft-Sauerstoft-Gemenge) zufügt.
Aber es ist dabei stets erforderlich, die Zusätze so zu wählen, dass das aus der Verbrennung hervorgehende Wasser- dampfvolum tunlichst klein bleibt.
Wenn man das Gas, nachdem es den Kühler passiert hat, unter Arbeitsleistung entspannen lässt, so kann man die Energie, welche zur Kälteerzeugung für die nachströmenden Anteile erforderlich ist, gewinnen. Indem man andererseits die Druckfiammen in Rohren brennen lässt, weiche durch Dampfkessel geführt sind, kann man ihre Verbrennungswärme zur Dampferzeugung und weiter zur Gewinnung der Arbeit nutzbar machen, welche für die Kompression aufzuwenden ist.
PATENT-ANSPRÜCHE :
1. Verfahren zur Erzeugung von Stickstofioxyden oder konzentrierter Salpetersäure aus Stickstoff und Sauerstoff enthaltenden Gasgemischen mittels durch Brennstoff erzeugter, ständig und unter Druck b1'ennender Flammen, dadurch gekennzeichnet, dass man als Brennstoff Kohlenoxydgas verwendet.
2. Ausführungsform des unter 1 beanspruchten Verfahrens, darin bestehend, dass man zur unmittelbaren Erzeugung von konzentrierter Salpetersäure passende Mengen von Wasserstoff oder wasserstoffhaltigem Brennmaterial oder von Wasserdampf bei der Verbrennung zuführt.

Process for gas mixtures containing nitrogen oxides or concentrated nitric acid from nitrogen and oxygen.
EMI1.1
<Desc / Clms Page number 2>
EMI2.1
without relaxation through a cooler, so Usst can easily achieve that separation of liquid resp. solid StickatoStetraoxide takes place without carbon dioxide being deposited. Concentrated nitric acid can also be produced directly by adding water vapor or hydrogen or hydrogen-containing fuels to the gases intended for combustion (the carbon oxide or the air or the air-oxygen mixture).
But it is always necessary to choose the additives so that the volume of water vapor resulting from the combustion remains as small as possible.
If the gas, after it has passed the cooler, is allowed to expand while performing work, the energy that is required to generate cold for the subsequent components can be obtained. On the other hand, by letting the pressure flames burn in pipes that are passed through steam boilers, their heat of combustion can be used to generate steam and further to gain the work that is required for the compression.
PATENT CLAIMS:
1. A process for the production of nitrogen oxides or concentrated nitric acid from nitrogen and oxygen-containing gas mixtures by means of flames generated by fuel and constantly blasting under pressure, characterized in that carbon oxide gas is used as fuel.
2. Embodiment of the method claimed under 1, consisting in supplying suitable amounts of hydrogen or hydrogen-containing fuel or of water vapor during the combustion for the immediate production of concentrated nitric acid.
