An absorption column is fed from the bottom with a gas that contains 5% benzene and 95% air. A non-volatile absorption oil that does not contain benzene is inserted from the top of the column. Others

Data are:

Total pressure: 1 atm

Temperature (constant): 26 C

Pressure drop: 1.5 in H20/ft packaging

Molecular weight of absorption oil: 230 g/mol

Density of the absorption oil: 900 kg/m3

Viscosity of the absorption oil: 4.0 cSt

Volume of gas entering: 0.3 m

Tower packaging: 12 in ceramic Rasching rings of nominal

Ratio between liquid flow and gas flow: 2,057 Ib of liquid/Ib of gas

Calculate the diameter of the tower.
