A solute A is being transferred from a binary gas mixture of A and C into a pure liquid solvent B in a counter current packed tower with a cross sectional area of 0.2 m2. The inlet gas contains 5 mol% of A and its desired to recover 87% percent of A from the gas stream. The feed gas flowrate is 3.7 mol/s and the liquid solvent inlet flowrate is 13 mol/s. ky’ah = 40 mol/m3s and kx’ah = 60 kmol/m3s. The equilibrium relationship can be assumed to be y = 1.2x.

Fp=185 ft2/ft3   

gas molecular weight, MG = 0.029 kg/mol     |          gas density, ρG = 0.9 kg/m3

liquid molecular weight, ML = 0.07 kg/mol    |          liquid density, ρL = 900 kg/m3

liquid viscosity, μL = 0.003 Pa×s       |      specific surface area of packing, ah = 50 m2/m3

what is the packing tower height
