Sulphuric acid mist is arrested by using a ____________ scrubber?
Correct answer: C. Venturi
- A. Packed wet
- B. Hollow wet
- C. Venturi
- D. Co-current
Explanation
A Venturi scrubber gives very high gas-liquid relative velocity, producing fine droplets that efficiently capture sulphuric acid mist. Packed and hollow scrubbers are generally less effective for such fine aerosols.
