Emissions
Dillon Consulting Limited was retained by BEST to conduct source testing on the gasifier exhaust stack to quantify combustion gas emissions. These tests were conducted with the gasifier operating at the maximum system designed production rate of approximately 500 pounds (227 kg) of straw feed stock per hour. The following gases were measured from the exhaust gas stream:
The following table summarizes the results of the combustion gas concentrations in the BEST gasifier exhaust stream. |

Combustion Gas concentrations are the average concentrations from 3 separate test periods.
“The results of the dispersion model indicate that the emissions of all of the measured parameters from the [BEST] Gasifier comply with the Ontario and Manitoba regulated Point of Impingement and Ambient Air Quality Criteria Concentrations. The POI concentrations for the remaining combustion gases do not exceed any of the regulated POI limits or AAQC. In general the POI concentrations predicted by the dispersion modeling for all measured pollutants are at least one-half of the regulated levels with no pollution control devices.” - Dillon Final Report, March 2003 |
