In the manufacture of sulphuric acid from elemental sulphur, the following sequence of major operations is followed ?
Correct answer: B. Furnace → converter → absorber
- A. Furnace → evaporator → absorber
- B. Furnace → converter → absorber
- C. Furnace → converter → evaporator
- D. Converter → furnace → absorber
Explanation
Sulfur is first burned in a furnace to produce SO₂, which is oxidized to SO₃ in the converter and then absorbed to form sulfuric acid. This gives the sequence furnace, converter, absorber.
