Typical air pollution control projects focus on the capture mechanism and a destruction device. With regulations driving towards higher capture efficiencies, combustion devices must treat larger volumes of air with lower concentration of pollutants. The Anguil concentrator technology is an energy and cost saving add-on to thermal and catalytic oxidizers that can reduce the amount of treated airflow by 95%. This greatly reduced flow is rich in emissions and much less of an operating cost burden on the destruction device.
