For assessing compliance with the emission standards of incineration plants, a correction needs to be applied to the measured concentrations of air pollutants. The emission standard (based on 11% Oxygen) for HCl is 50 mg/Nm3. If the measured concentrations of HCl and Oxygen in the flue gas are 42 mg/Nm3 and 13% respectively, and assuming 21% oxygen in ambient air, which statement is CORRECT?

Share:
- 1No compliance, as the corrected HCl emission is greater than the emission standard.✓
- 2Compliance is there, as there is no need to apply the correction since Oxygen is greater than 11%.
- 3Compliance is there, as the corrected HCl emission is lesser than the emission standard.
- 4No compliance, as the Oxygen is greater than 11% in the flue gas.
Correct answer
No compliance, as the corrected HCl emission is greater than the emission standard.
