Abstract

By a new “sampling” technique using thermocouples to measure the condensation temperature of vapour mixtures in a wetted‐wall fractionating column, it has been possible to derive curves of vapour concentration along the contact path of the two phases. From these “concentration curves” estimations have been made of the effect on H.T.U. of vapour composition for various column lengths and operating conditions. Discrepancies between data obtained from the same type of column by other workers are found to be due primarily to the effect of vapour composition. The present analysis indicates clearly the limitations of H.T.U. assessments based on the resistance to diffusion of the vapour film alone.
