OVERALL SHERWOOD NUMBER ESTIMATION IN PULSED PACKED LIQUIDLIQUID EXTRACTION COLUMN

Using plug flow model in conjunction with experimental solute concentration profiles, overall volumetric mass transfer coefficient based on continuous phase (Koca), in a pulsed packed liquidliquidextraction column has been optimized. Number of 12 experiments has been done using standard system of water/acetone/n-butyl acetate in a 7.5 cm diameter, 1.5 m height column. Thorough consideration of influencing parameters we intendedto correlate dimensionless parameters in term of overall Sherwood number which has an acceptable average error of about 16%.
