Assignment:
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.
Provide complete and step by step solution for the question and show calculations and use formulas.
