NOx Emissions Control

Recirculation of Dryer Flows with VOCs.

There are different industrial processes in which NOx is produced and is then, eliminated into the atmosphere

There are several techniques for treating these contaminating gases to reduce the emission levels. These techniques include injecting oxygen or ozone into the exhaust gas emission flow, which is an effective, flexible and economical method of adjusting the industrial facilities to optimum emission levels.

Injecting oxygen into the exhaust gas emission flow is an effective, flexible and economical method of adjusting the industrial facilities to optimum emission levels.

Nippon Gases has developed for several clients different oxygen injection systems to decrease these contaminating gases


The results have been very positive in all cases.

This treatment only requires the installation of a

small oxygen injector, generally at the gas exhaust

point. Oxygen acts in this case as an oxidising

chemical compound.
