Problem 3 (28 points) Situation: This problem has to do with the recovery of methanol from a gaseous stream by absorption into water in a tray tower (the gas solvent does not absorb). The mass flow rates at the bottom, densities, and surface tension are as follows: • Gas stream: 2.2 [kg/s); 1.8 [kg/m3] • Liquid stream: 0.9 [kg/s]; 990 [kg/m3]; 0.065 [N/m] • Other - Water density: 1,000 [kg/m3); Reference surface tension: 0.02 [N/m]; Tray data are as follows: • Tray spacing of 60 [cm]; weir height of 4 [cm]; tray (metal) thickness: 2.5 [mm] • Tray layout: Hole diameter of 5 [mm] in an equilateral triangular pitch of 18 [mm] • Other data: Foaming factor of 0.90; flooding approach of 75% Requirements: Please, select the best answer for the following statements: 1. The surface-tension factor is: ► . 2. The area factor (FHA) is: 3. The constant CF, in [m/s], is: 4. The empirical constant C, in [m/s], is: 5. The superficial gas velocity at flooding, in [m/s], is: > 6. The column diameter, in [m], is:
