An odor removal system to neutralize odors and VOC emissions released into the environment by commercial and/or industrial air streams utilizes Non-Thermal Plasma (NTP) to create a range of Reactive Oxygen Species (ROS) to cause the oxidation and/or reduction of odor causing molecules and VOC=s. The ROS is generated by drawing atmospheric and/or odorous air through a Dielectric Barner Discharge Plasma Generation Cell (DBDPGC). The gas is activated by passing it through the non-thermal plasma field in the DBDPGC producing the ROS that are then immediately mixed into the odorous gas stream to be treated or if it is the odorous gas that is passing through the NTP field it is inherently mixed. …
