Ozone application to a two-stage NO removal from waste gases

Jaroszynska-Wolinska J.

Polish Journal of Chemical Technology

2002

Vol. 4, nr 2

5-7

Technological development in the domain of ozone generation technology enlarges the scope of ozone applications significantly. Among them there is an application in a process of oxidation-absorption of diluted nitrogen oxide used for the reduction of the emission. The use of ozone appears to be very attractive from the point of view of technological processes. The paper presents the results of the research experiments that indicate a possibility of significant intensification of the absorption process of the NO in water in the presence of ozone. It has been proved that in certain conditions the gas-liquid mass exchange coefficient for nitrogen oxides almost doubles as compared to oxygen from the air. The degree of NO elimination from gas can reach 90% even in the case of the low initial NO concentration.
