Commercial packed scrubbers are normally designed for a pressure drop range of ______________ mm water column per metre of packed height?
Correct answer: B. 17-34
- A. 4-8
- B. 17-34
- C. 52-68
- D. 88-105
Explanation
Commercial packed scrubbers are commonly designed for a pressure drop of about 17 to 34 mm water per metre of packing. Excessive pressure drop signals flooding or uneconomically high gas velocity.
