3 Destroys VOC with the three T's of combustion: TimeTemperatureTurbulence Achieves 75-99% reduction in the emissions entering the device emissions entering the device Thermal Oxidation

4 Direct Flame vs. Catalytic Capital CostsCapital Costs Operating Cost (auxiliary fuel)Operating Cost (auxiliary fuel) Operating TemperatureOperating Temperature

5 Slow Catalyst Poisons Iron Tin Silicon Halogens Sulfur Zinc Phosphorous Lead Arsenic Antimony Mercury Bismuth Reversible Catalyst Inhibitors Fast Acting Catalyst Poisons I bought the equipment. Why does it still smell?

6 Catalysts are Subject to: Thermal Aging - Heat Cycles Cause the Metal to Recrystallize in an Ineffective Form Burnout - Excessive Heat "Boils" the Metal off the Substrate Gumming - Surface Area is Covered by Heavy Organics From Paint or Fuel Oil

7 Check Incinerators For: Auxiliary Fuel FlowAuxiliary Fuel Flow Gas Flow from Booth to StackGas Flow from Booth to Stack Outlet Temp. Higher than Inlet Temp.Outlet Temp. Higher than Inlet Temp. Inlet VOC Concentration Higher than Outlet VOC ConcentrationInlet VOC Concentration Higher than Outlet VOC Concentration Bypass Stack EmissionsBypass Stack Emissions

8 Electromagnetically attracts VOC onto activated carbon Achieves 40 to 65% reduction Carbon Adsorption

31 Henry V on Air Pollution Control Here, at the turn of the century, air control is entering a new time.. Years from now your young colleagues will ask about oh- nine That time before things were so clear. As you speak, they will lean forward, straining to hear. You’ll tell them how things wound up this way. And they will hold their careers as cheap, those who were not here, To fight with us this day.
