Question:
For assessing the compliance with the emissions 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 and the measured concentrations of HCl and Oxygen in flue gas are 42 mg/Nm3 and 13%, respectively.
Assuming 21% Oxygen in air, the CORRECT statement is:

- No compliance, as the corrected HCl emission is greater than the emission standard.
- Compliance is there, as the corrected HCl emission is lesser than the emission standard.
- Compliance is there, as there is no need to apply the correction since Oxygen is greater than 11% and HCl emission is lesser than the emission standard.
- No compliance, as the Oxygen is greater than 11% in the flue gas.
