Abstract
A study of the mass transfer phenomena in fractional distillation was made. Small scale single slot, single cap apparatus was used to obtain the necessary experimental data.
The mass transfer coefficient KgA was calculated using several combinations of liquid and vapor compositions in the menthanol - water system under static liquid conditions. The correlation showed that KgA held about constant over the entire range of concentrations.
The problem of bubble area was studied and reasonable estimations of area, bubble frequency, and time of rise were made. This information is to be incorporated into the calculation of the mass transfer coefficient for the continuous procedure.
The apparatus used in the static liquid experiments was modified to permit a continuous procedure with liquid flowing across the plate. The steady state liquid and vapor compositions were determined and Murphree efficiencies were calculated. A study of possible methods of calculating the mass transfer coefficient Kg from the available data was made.
