QUESTION
Acetone is being absorbed by water in a packed tower having a crosssectional area of at and atm The inlet air contains mol acetone and the outlet contains mol The gas flow is kgmolinertai The purewater inlet flow is kgmol water The following are the mass transfer film coefficients and the corresponding values at the interface. The equilibrium data is given by
Film mass transfer coefficient Value Unit
Kgmomol frac
kgmomol frac
a Determine the flowrate and composition of each stream: some are already given but some you may have to calculate from the mass balance
b Use and and also and to determine the tower height. The formula is given below. Compare the results.
The interface composition is
