Title: Experimental Measurement Of Drop Phase Mass Transfer Coefficients For The Carbon Tetrachloride-Acetic Acid-Water System
Author: Javed, K. H.
Abstract: The overall mass transfer coefficients of single drops of carbon tetrachloride falling in a stagnant continuous phase of water containing acetic acid as solute were measured experimentally for different dispersed phase flowrates and drop falling times. The measured mass transfer coefficients were lower than those estimated from the mass transfer models for circulating drops but were reasonably in agreement with the stagnant drop model. The observed deviation is attributed to the slow dimerization reaction which occurs in this system during the transfer of acetic acid. The agreement with the stagnant drop model indicates that even for turbulent 'droplet conditions the mass transfer in this system is governed by molecular diffusion.
