+1 862 207 3288 A tower packed with 25-mm 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 CP and its density is 840 kg/m3. The liquid mass velocity is G, = 2.7 1 kg/m2-s. Estimate the liquid holdup, the void fraction, and the hydraulic specific area of the packing.
