The empirical equations for predicting the height of the gas and liquid film transfer units [9]  

The term of diameter correction is taken as fixed 2.3 for diameter greater than 0.6 m. 

K3 = 1 for percentage flooding less than 45, and the following approxi-mafe equation can be used for a higher percentage of flooding F  

The total height of the column may be calculated from the following correlation  

Equation 7.34 was developed from information reported by gas absorber vendors, and is applicable for column diameters from 2 to 12 feet and packing depths from 4 to 12 ft. The surface area (S) of the gas absorber can be calculated using the equation
