Electrostatic Precipitator is used in Thermal Power Plants to remove which of the following air pollutants?

Correct option is C

Introduction

Electrostatic precipitators (ESPs) are devices used to control air pollution by removing particulate matter from gas streams. In thermal power plants, ESPs play a crucial role in reducing emissions.

Information Booster

·       ESP's primary function is to remove Fly ash and other particulate matter from the flue gas emissions of thermal power plants.

·       Fly ash is a byproduct of coal combustion and can cause significant air pollution if not properly controlled.

Additional Knowledge

   Polycyclic Aromatic Hydrocarbons (PAHs): These are organic compounds that can be emitted during coal combustion. However, ESPs are not specifically designed to remove PAHs, which are typically controlled using other technologies like activated carbon or scrubbers.

 Gaseous Pollutants: ESPs are not effective in removing gaseous pollutants, such as SO2, NOx, or CO2. These pollutants require separate control technologies like scrubbers or selective catalytic reduction.

Volatile Organic Compounds (VOCs): Like PAHs, VOCs are not typically controlled using ESPs. Instead, technologies like activated carbon, scrubbers, or thermal oxidation are used to remove VOCs from gas streams.

The correct answer is: Fly ash. Electrostatic precipitators are specifically designed to remove particulate matter like fly ash from the emissions of thermal power plants.
