Transfer Coefficients in a Column with Structured Packing

Example 12.3.2 Mass Transfer Coefficients in a Column with Structured Packing 

Estimate the mass transfer coefficients, interfacial area, and the heights of transfer units for the system in Example 12.3.1, namely, acetone (l)-water (2), in a column equipped with Sulzer BX structured packing. The characteristics of this packing are (Bravo et al., 1985). 

SOLUTION We begin by computing the equivalent diameter from Eq. 12.3.40 

the liquid flow rate per unit length of perimeter is r = p u / PA,  

The mass transfer coefficient for the vapor phase is computed from the definition of the Sherwood number (Eq. 12.3.39), as
