A New Correlation for Overall Sherwood Number in Packed Liquid-Liquid 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 packed
liquid-liquid extraction column has been optimized. Number of 12
experiments has been done using standard system of water/acid
acetic/toluene in a 6 cm diameter, 120 cm height column. Thorough
consideration of influencing parameters we intended to correlate
dimensionless parameters in term of overall Sherwood number which
has an acceptable average error of about 15.8%.
