- A Gas Mixture Containing 90 2 Mole Co And 9 8 Mole Ethanol Is Passed Through An Absorption Tower To Separate Ethano 1 (217.32 KiB) Viewed 10 times
A gas mixture containing 90.2 mole % CO, and 9.8 mole % ethanol is passed through an absorption tower to separate ethanol using water as solvent. The gas mixture enters from the bottom of the tower at a rate of 7997 m/h, at 298 K and at a pressure of 1.11 atm. Water enters from top of the tower with a flow rate of 6470 kg/h and at 298 K. The expected recovery of ethanol will be 88 %, and the maximum permissible pressure drop for the gas stream should not exceed 250 N/m? The value of the Henry's law constant for the ethanol - water system corresponding to a temperature of 298 Kis H = 0.270 atm. Assume 69 % flooding condition. Use the equilibrium relationship y* = m x. Select a 50-mm ceramic raschig rings as packing material, Evaluate the following with suitable assumptions. 1) Number of ideal stages; 10 I 2) Flow Parameter: 10 3) Tower diameter: 10 4) Mass flow rate of liquid 05 5) Packing Height 05 6) Effective interfacial area of packing per unit volume; 05 7) Draw to scale the sketch of packed bed absorption tower with label; 05
