Laboratory tests are being made prior to design of an absorption column to absorb bromine (left(mathrm{Br}_{2} ight))

Laboratory tests are being made prior to design of an absorption column to absorb bromine \(\left(\mathrm{Br}_{2}\right)\) from air into water. Tests were made in a laboratory packed column that is \(0.1524 \mathrm{~m}\) in diameter, has \(1.524 \mathrm{~m}\) of packing, and is packed with saddles. The column was operated at \(20.0^{\circ} \mathrm{C}\) and \(5.0 \mathrm{~atm}\) total pressure, and the following data were obtained:

Inlet solvent is pure water.
Inlet gas is \(2.0 \mathrm{~mol} \%\) bromine in air.
Exit gas is \(0.2 \mathrm{~mol} \%\) bromine in air.
Exit liquid is \(0.1 \mathrm{~mol} \%\) bromine in water.
What is the \(\mathrm{L} / \mathrm{G}\) ratio for this system? (Base your answer on flows of pure carrier gas and pure solvent.) What is the HETP obtained at these experimental conditions? Henry's law data are given in Perry et al. (1963, pp. 14-2 to 1412). Note: Use mole ratio units. Assume that water is nonvolatile and air is insoluble.
