Naphthalene is removed from coke oven gas by________________?
Correct answer: C. Scrubbing with wash oil (a petroleum product)
- A. Absorbing in vetro-coke solution
- B. Adsorbing on bog iron bed
- C. Scrubbing with wash oil (a petroleum product)
- D. None of these
Explanation
Naphthalene is removed from coke-oven gas by absorption in wash oil, a petroleum fraction that dissolves the hydrocarbon vapours. Bog iron is associated with gas purification in other contexts, not the usual naphthalene-removal method.
