Traces of tar fog present in the coke oven gas is removed by_________________?
Correct answer: D. Electrostatic precipitator
- A. Cyclone separator
- B. Wet packed scrubber
- C. Washing with monoethanolamine
- D. Electrostatic precipitator
Explanation
An electrostatic precipitator effectively removes fine tar fog droplets from coke oven gas by electrically charging and collecting them on plates. A cyclone is better for coarse solid particles, while monoethanolamine removes acidic gases rather than tar fog.
