Packed tower design random-dumped packing

In liquid-film-controlled systems the value of Koa primarily is a function of the liquid flow rate. For most random dumped tower packings the value of the exponent b in Equation 3-13 lies between 0.22 and 0.34 the exact value is characteristic of the type of packing employed. If data on the particular packing are not readily available, it is suggested that this exponent be assumed as 0.30 for preliminary designs. In such liquid-film-controlled systems there is a very small effect of gas rate. The value of the exponent c in Equation 3-13 normally is only 0.06 to 0.08. Thus, if a standard Koa value for such a system is determined to be 6.0 Ib-mol/h...
