Situation This Problem Has To Do With The Recovery Of Methanol From A Gaseous Stream By Absorption Into Water In A Tray 1 (37.37 KiB) Viewed 18 times

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: 2.1 [kg/s) 1.7 [kg/m3] • Liquid stream: 0.7[kg/s): 990 [kg/m): 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 12 [mm] • Other data: Foaming factor of 0.90; flooding approach of 70 % . 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 Crin (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:
