It is desired to reduce the 2% CO, in 23 Ib/sec of a natural gas stream using absorption in aqueous diethylamine flowing at 40 lb/sec. Either 1 ½ in. Raschig rings or 1 ½ in. Pall rings are being considered for packing. A pressure drop of 0.25 in H2O/ft is desired to minimize foaming. Under operating conditions, the densities of the gas and the liquid are 2.8 and 63 Ib/ft³, respectively; the liquid viscosity is 2 centistokes. "Determine the flooding velocity and the tower's cross-sectional area using the succeeding procedures
