Fractional dispersed phase hold-up and overall dispersed phase side mass transfer coefficients were measured in 34, 50, 70 and 95 mm i.d. spray columns using an aqueous two phase system. Sodium sulphate-polyethyleneglycol (PEG) (4000)-water formed the aqueous two phase system and amyloglucosidase was used as a solute for the estimation of mass transfer coefficient. The dispersed phase hold-up (eD) and volumetric dispersed phase side mass transfer coefficient (KD) both increased with increasing PEG-rich phase velocity. The eDand KDawere found to be independent of the column diameter and column height above a certain critical value. An increase in the phase concentration of sodium sulphate and PEG was found to reduce eDand KDEmpirical and semi-empirical correlations for eD and KDahave been developed. |
