Consider the following comparisons between Flue Gas Desulphurisation (FGD) and Electrostatic Precipitators (ESP) based on the NIAS study:
FGDs are more expensive to install per MW than ESPs.
FGDs help in controlling PM emissions more efficiently than ESPs.
ESPs have been developed domestically by a public sector company.
Which of the above statements is/are correct?

Question

The correct option is B i.e., 1 and 3 only.

FGDs are indeed more expensive to install per MW than ESPs thus, making statement 1 correct.
Statement 2 is incorrect as ESP is better at PM reduction; FGD is for SO₂.
Statement 3 is also correct since ESPs have been developed domestically by BHEL, a public sector company.
