Abstract
Verfahren zur Herstellung von N2O5 durch Oxidation von NO2 mit Ozon mit den Schritten a) Erzeugen eines Hauptgasstromes, enthaltend Ozon; b) Erzeugen eines Nebengasstromes, enthaltend NO2; c) Einspeisung des Nebengasstromes in den Hauptgasstrom, wobei ein Gesamtgasstrom gebildet wird; d) Durchleiten des Gesamtgasstromes durch einen Stroemungsreaktor, wobei NO2 mit Ozon reagiert; e) Abscheiden von gebildetem N2O5, wobei in einer Mischkammer der Nebengasstrom in den Hauptgasstrom in einem Winkel zum Hauptgasstrom eingespeist wird, wobei der Stroemungsquerschnitt des Hauptgasstromes derart vor der Einspeisungsstelle des Nebengasstromes in den Hauptgasstrom verringert wird, dass die Stroemungsgeschwindigkeit des Hauptgasstromes an der Einspeisungsstelle erhoeht ist.
EP 983965 A UPAB: 20000412 NOVELTY - A secondary gas stream is injected into the main gas stream in a mixing chamber at an angle of 10-170 deg. to the main gas stream. The flow cross-section of the main gas stream before the injection site of the secondary gas stream into the main gas stream is reduced in such a way that the flow speed of the main gas stream is increased. DETAILED DESCRIPTION - Production of dinitrogen pentoxide comprises: (a) forming ozone containing a main gas stream; (b) forming nitrogen dioxide containing a secondary gas stream; (c) injecting the secondary gas stream into a main gas stream; (d) feeding the total gas stream formed through a flow reactor in which nitrogen dioxide reacts with the ozone; and (e) removing the dinitrogen pentoxide formed. The secondary gas stream is injected into the main gas stream in a mixing chamber at an angle of 10-170 deg. to the main gas stream. The flow cross-section of the main gas stream before the injection site of the secondary gas stream into the main gas stream is reduced in such a way that the flow speed of the main gas stream is increased. An INDEPENDENT CLAIM is also included for the apparatus for carrying out the production of dinitrogen pentoxide. USE - None given. ADVANTAGE - Effective mixing of the two gas streams is achieved.
