3. Who Are We • Alberta Welltest Incinerators is a private Alberta Company dedicated to reducing the environmental impact of oil & gas related production test flaring. • The AWI low emission burner technology provides a significant advancement over existing conventional flares and available enclosed flaring equipment. • AWI has over 80 years experience in incineration and production testing

5. What We Do

6. How Do We Do It • Computer Controlled • Designed to feed the perfect amount of air for the combustion reaction under any volume or combination of gases. • Engineered Design • Built with the required height, diameter, air volume and burner design to meet the all the requirements for a complete and efficient burn. • Three T’s of Combustion • Sufficient Residence Time for Complete Combustion • High Volumes of Dilution Air • Dramatically improves SO2 Ground Level Concentrations

7. Control System

8. Incineration 101 • Three T’s of Combustion • Time, Temperature and Turbulence • The mixing of fuel and air to complete the combustion reaction must take place at an elevated temperature and reside at that temperature for a predetermined length of time. • There exists a relationship between the degree of mixing (Turbulence), the Temperature at which the components are mixed and the length of Time the mixed components stay at that temperature. • Excess Air will rob the heat energy away from the reaction, lowering the temperature to below the ignition temperature of the fuel…..resulting in unburnt hydrocarbons, smoke, odour, poor emissions.

9. Incinerators or Flares…? Impossible to Control the Combustion Reaction with a Flare

10. Incinerators vs. Flares • Conversion Efficiencies • Under perfect laboratory conditions - 99.5% (recent U of A Study) • Can be significantly below 95% combustion efficiencies • Windy days • Black smoke • May require Enrichment Gas for Sour Well Applications • May be the better choice in certain cases – But, still require perfect conditions to burn effectively • Higher exit elevations • Very high H2S concentrations

11. Reduction in Greenhouse Gasses • The Global Warming Potential of methane is over 20 times higher than CO2. Inefficient combustion of Welltest gases with a flare or enclosed flaring system will significantly increase the Greenhouse gases emitted. • For example 19,000 SCFD of waste methane gas can generate the equivalent of the following daily CO2 emissions...

12. Other Choices? • Not All incinerators are the alike! • Enclosed Flares – Decoys • Very High Radiant Heat Temperatures • Potential for Matting, Field or Forest Fires (Liability) • Difficult and/or Hazardous to Operate • NO Temperature Control or Monitoring • Noise Issues • Exit Elevation - Below 40’ • Low residence time • Poor SO2 GLC • Inconsistent Air for Proper Combustion • Low Dilution rates • No Containment Devices for Carryover – Potential for Spills or Fires • DO NOT MEET AER Directive 60 Requirements for Sour applications • Misleading Throughputs

13. Why request an AWI incinerator?
