bed absorption colt is discharged to atmosphere. The gas stream will be passed through a packed bed absorption column where it is contacted with pure liquid absorbent in counter current operation to reduce the concentration of the hazardous gas from 7% mol to 0.1%mol. The gas flow rate is 10m3/min and the liquid absorbent flow rate is 3m3/min. Calculate: - Mass transfer rate N. - Overall mass transfer coefficient based on the gas phase K00. Additionol information: Operating pressure: 2.5atm Operating temperature: 50C Molecular weight of the hazardous gas: 45 Molecular weight of liquid absorbent: 56 Density of liquid absorbent at 15C:850kg/m3 Ideal gas constant: 8.205101m3atm/molK Column height: 8m Column diameter: 1.25m Effective interfacial area per unit packing: 600m2/m2 Kog=aAZN(P1Poln(P0P1))
