Description

Verfahren zur Verbesserung der Absorption nitroser Gase durch Wasser. Die Erfindung betrifft eine weitere Ausbildung des Verfahrens zur Verbesserung der Absorption nitroser Gase durch Wasser nach Patent 345668.Process for improving the absorption of nitrous gases by water. The invention relates to a further embodiment of the method for improving the Absorption of nitrous gases by water according to patent 345668.

Nach dem geschützten Verfahren wird die zirkulierende Absorptionsflüssigkeit vor ihrer Rückkehr in den Absorptionsprozeß mit frischer Luft oder anderen sauerstoffhaltigen Gasen im Gegenstrom ausgeblasen. Die Anwendung sauerstoffhaltiger Gase wurde deswegen vorgeschlagen, um die nitrosen Gase, die in der Hauptsache aus N2 03 bestehen, zu N2 0, zu oxydieren. Da,es j edoch bei dem Verfahren in der Hauptsache darauf ankommt, die Absorptionsflüssigkeit von nitrosen Gasen zu befreien, um der Absorptionsflüssigkeit eine stärkere Absorptionsfähigkeit zu verleihen, ist die Anwesenheit von Sauerstoff im Gasstrom nicht unbedingt notwendig. Es genügen für die Ausblasiezwecke auch Gase, wie Stickstoff, gereinigte Rauchgase, die überhaupt keinen Sauerstoff enthalten. Es tritt dabei lediglich eine geringfügige Vermehrung des zu absorbierenden Gasquantums durch inerte Gase ein, die aber für die Wirksamkeit der Absorption nicht von Belang ist.According to the protected process, the circulating absorption liquid is blown out in countercurrent with fresh air or other oxygen-containing gases before it is returned to the absorption process. The use of oxygen-containing gases was therefore proposed in order to oxidize the nitrous gases, which mainly consist of N2 03, to N2 0 . Since, however, the main thing in the process is to free the absorption liquid from nitrous gases in order to give the absorption liquid a stronger absorption capacity, the presence of oxygen in the gas stream is not absolutely necessary. Gases such as nitrogen, purified smoke gases that do not contain any oxygen at all, are also sufficient for blowing out purposes. There is only a slight increase in the amount of gas to be absorbed by inert gases, but this is not important for the effectiveness of the absorption.
