Quaternary System in a Sulzer Packed Column

Example 12,3.3 Distillation of a Quaternary System in a Sulzer Packed Column 

Gorak (1991) conducted a number of distillation experiments with the system acetone(l)-methanol(2)-2-propanol(3)-water(4) in a column of 0.1-m internal diameter and height 0.8 m fitted with Sulzer BX structured packing. The characteristics of Sulzer BX packing are (Bravo et al., 1985).

Estimate the mass transfer coefficients and the numbers of transfer units for this system at the following conditions that existed at the bottom of the packing in one of Gorak s experiments. 

DATA Physical properties of the vapor and liquid phases at the composition reported above and at the bubble point temperature of the liquid have been estimated as follows
