Verfahren und Vorrichtung zur Herstellung von Distickstoffpentoxid

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
