Clean Combustion. Clear Solutions. Thermal Oxidizer TANGENT Technology TM Breakthrough technology John Zink® Company has developed TANGENT™ technology to yield ultra-low emissions without raising CO levels. Breakthrough emissions John Zink testing has shown less than 1 ppm NOx and CO. Ultra-low emissions levels can allow greater waste processing capacities under existing permits. Reducing NOx levels to near zero may result in NOx emission credits. BREAKTHROUGH NOISE & VIBRATION levels TANGENT Technology U.S. Patent Pending. TANGENT technology generates markedly less noise and vibration than conventional systems. BREAKTHROUGH OPERATION Selective Catalytic Reduction (SCR) or Selective NonCatalytic Reduction (SNCR) may be eliminated. If so, start-up time is reduced, fewer utilities are needed, and there is less equipment to maintain. TANGENT technology requires no citing, storage, or disposal of ammoniacal reagents such as NH3/Urea, nor the associated regulatory burdens. BREAKTHROUGH DIMENSIONS And, TANGENT technology distributes temperature and TANGENT technology can eliminate post-combustion heat much more uniformly resulting in less thermal equipment and greatly reduce the amount of plot space stress on refractory and burner components. otherwise required for similar NOx performance.

Thermal Oxidizer TANGENT Technology TM The following comparisons illustrate the potential Sulfur Plant Tail Gas NOx reduction that could be achieved by using the Tangent process compared to emission estimates from traditional commercial systems. Tangent Emission values were scaled from data obtained at the John Zink test facility in Tulsa, Oklahoma during 2009. Ethanol Plant Dryer Off Gas Tail Gas Flow (lb/hr) Stack O2 (vol%) T.O.
