Question:

A tower packed with $25 - m m$ ceramic Raschig rings is to be used for absorbing benzene vapor from a dilute mixture with an inert gas using a wash oil at $300 K$ .

The viscosity of the oil is $2.0 c P$ and its density is $840 k g / m^{3}$ . The liquid mass velocity is $G_{x} = 2.71 k g / m^{2}$ -s. Estimate the liquid holdup, the operational void fraction, and the hydraulic specific area of the packing.
