Correct answer: B. Quenching of hot coke
- A. Discharging in the river stream
- B. Quenching of hot coke
- C. Filtration and recycling for cooling coke oven gas
- D. None of these
Explanation
Phenolic wastewater from coke ovens has traditionally been reused for quenching hot coke, which consumes the water and limits direct discharge. Discharging it untreated to a river would cause serious pollution, while filtration and recycling for gas cooling is not the standard stated disposal method.
