Paper Abstract

Chemical and biological warfare materials create difficulties when designing or retrofitting high value targets such as buildings to withstand terrorist attack. The gas-phase corona reactor (GPCR) is a synergistic combination of plasma (or ionized gas) and catalyst technologies to produce an air purification system. The GPCR has demonstrated both chemical agent decomposition and biological material deactivation creating a universal air purification system. The benefits of GPCR include: (1) low temperature and atmospheric pressure operation; (2) small capital and operating costs; (3) minimal energy requirements; (4) NOx removal; (5) potential for low maintenance due to limited catalyst fouling; (6) straightforward operation with high, non-specific destruction efficiency; (7) treatment of bioaerosols and toxic chemicals; (8) compliance with federal and state indoor air regulations; (9) instant operation. The GPCR can be utilized for the protection of high value targets whether the attacks occur on the exterior or interior of a building. Overpressure operation of the building with the make-up air channeled through the GPCR can create a safe zone when the attack is external to the building. The damage and fatalities of a terrorist chemical and biological material dissemination within a building can be minimized with retrofitted GPCRs incorporated into the recirculation of the ventilation system.
