Repeat Example 4.2 but using Montz metal B1-200 structured packing (very similar to the one shown in Figure 4.3). For this packing, $a=200 \mathrm{~m}^{-1}, \varepsilon=0.979$, $C_{S, T}=3.116$, and $C_{F, T}=2.339$ (Billet and Schultes, 1999).

Data From Example 4.2:-

Air containing 5 mol% NH₃ at a total flow rate of 20 kmol/h enters a packed column operating at 293 K and 1 atm where 90% of the ammonia is scrubbed by a countercurrent flow of 1500 kg/h of pure liquid water. Estimate the loading and flooding superficial gas velocities for two packing materials:

(a) 25-mm ceramic Raschig rings

(b) 25-mm metal Hiflow rings
