Abstract: A dripping plate column fitted with perforated trays was used in studying the mass transfer for non-Newtonian liquids. The rate of vaporization of aqueous polymer solutions rheological behavior with power-law was measured in the column. It was found that temperature, pressure, mass flow rate and the non-Newtonian behavior of the solution are significant factors influencing mass transfer rate, which increases with increasing temperature and mass flow rate, and with decreasing pressure and fluid consistency. Based on these experimental data, a correlation for the Colburn factor, jm, was developed: jm= 2.2708 × 10-5Re-0.7013 It can be used to design flash columns for monomer discharge from polymer solutions.
