  1. CAP publications

  2. Thermal Oxidation • Destroys VOC with the three T's of combustion: • Time • Temperature • Turbulence • Achieves 75-99% reduction in the • emissions entering the device

  3. Direct Flame vs. Catalytic • Capital Costs • Operating Cost (auxiliary fuel) • Operating Temperature

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

  5. 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 Catalysts are Subject to:

  6. Auxiliary Fuel Flow Gas Flow from Booth to Stack Outlet Temp. Higher than Inlet Temp. Inlet VOC Concentration Higher than Outlet VOC Concentration Bypass Stack Emissions Check Incinerators For:

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

  8. Data Collection Requirements grams of VOC/ltr of coating Auto Ref grams of VOC / gram of solids applied Wood finishing Reactivity based rule Aerosols Architectural (planned)

  9. Cup Liners • Two manufacturers • Disposable • Save gun cleaning emissions (1.5 Pints reduced to 2 ozs) • Not yet required by anyone.

  10. Specific Low ROC Limits for: Group I Vehicle Coatings Group II Vehicle Coatings Automotive Requirements

  11. Passenger Cars, Light and Medium Sized Trucks and Vans, Large/Heavy Duty Truck Cabs and Chassis, and Motorcycles Group I Vehicles Means

  12. Public Transit Buses and Mobile Equipment Group II Vehicles Means:

  13. Specific District Approval Required for "Extreme Performance" Exemption Spray Equipment Must be Cleaned in an Enclosed System ROC Contaminated Waste Stored in Closed Containers Automotive Requirements

  23. Air Drying an Acrylic Enamel

  24. 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.

  25. Flip/flop an angle sensitive characteristic of metallic coatings and a color match challenge

  26. Clearcoat: • A Colorless Binder Strong Enough to Serve as a Topcoat Without the Reinforcement of a Pigment Providing a Wet Look to an Earlier Colorcoat • Today More Than 60% of Factory Finishes are Color/Clear (p200-20)

  27. Advantages of Color/Clear Technology • Maximum Luster and Strength • Clearcoat Now Available in Low VOC Water-Borne Formulation

  28. Color/clear metallic
