LIQUID-LIQUID MASS TRANSFER IN AN AGITATED VESSEL WITH A FLAT INTERFACE

抄録

Mass transfer between two phases was studied in an agitated vessel with a flat liquid-liquid interface for 30 systems, where physical properties varied in a wide range. The observed Sherwood numbers for the first-phase Sh₁ were correlated in terms of the first-phase Reynolds number Re₁, modified second-phase Reynolds number Re₂'', Schmidt number Sc₁, Capillary number Ca₁ and a function of viscosity ratio Φ. The correlation obtained represents all the data with an average deviation of 12.7%:
Sh₁ = O.O119Sc₁^1/3Ca₁^6/13[Φ⁴Re₁³+Re₂''^8/3]^1/4
