The observed point efficiencies on overall gas basis seemed to vary markedly with composition in low and high concentrations. It was demonstrated that these variations could not be attributed to lack of precision in the equiibrium data, interference with the column operation by sampling, variation in physical properties with composition, or a variation in stripping or rectifying factor mV/L with concentration.
The point efficiencies at total reflux seemed to be a function of the corresponding driving forces for mass transfer in the gas phase.
