Abstract
Ternary equilibrium data in the liquid-liquid system, calculated on thermodynamic basis by use of the arranged NRTL equation, are compared with the distribution coefficients of individual components and concentrations of the extracted component, obtained by the correlation according to Rod. On simple extraction examples, the effect of quality of equilibrium data on the results of chemical engineering calculation of the number of equilibrium stages at countercurrent extraction, is evaluated.
