Mass Transfer in the Presence of an Inert Gas

Example 11.53 Interphase Mass Transfer in the Presence of an Inert Gas 

Diameter of column, d = 0.025019 m. Helium flow rate = 0.2438985 mol/s. Vapor inlet temperature = 36°C. 

Liquid flow rate = 5.5439 X 10 kg/s. Liquid inlet temperature = 36.45°C. Inlet pressure = 129.81 k Pa. 

Estimate the mass fluxes at the top of the wetted wall column. 

ANALYSIS N/q shall use the turbulent eddy diffusivity model to represent the transport processes in the vapor phase. The mass fluxes in the vapor phase will, therefore, be calculated from
