Integrated Applied Physics has developed an exhaust gas treatment system for effectively controlling emissions of NO{sub x}, SO{sub 2} and VOCs. The system is an after treatment that can be added to existing coal fired boilers, waste incinerators and diesel engines without modifying the combustion process. Non-Thermal plasma processes are used to efficiently destroy gaseous pollutants. The non-thermal.plasma process deposits energy selectively into components of the gas to drive chemical reactions that destroy Pollutants. This is in contrast to thermal techniques where all components of the gas are heated equally and consume energy. The end result is lower energy use and a lower cost for the treatment system. To implement the non-thermal plasma process, high voltage power systems are required producing short pulses of high power. Previously there have been no commercial power systems suitable for effectively implementing these processes.Integrated Applied Physics has made a significant advancement in the power systems used in the non-thermal treatment process. These power systems use short pulses to effectively drive energy into the non-thermal plasmas resulting in a high electrical efficiency. These systems make non-thermal plasma treatment feasible both technically and economically. The proprietary design and components used give the system advantages in reliability, efficiency and cost. Our treatment system has been applied to diesel engine exhaust for NOx reduction. With 200 watts treatment power 90% NO removal has been obtained on a 52 cfm exhaust flow from a diesel engine. The treatment requires an electrical input power that is less than 2% of the engine output power.
