GATE CE 2024 ce-1 Q43: Air Pollution

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:

Your answerChoose one option.

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.
