F1. Laboratory tests are being made prior to the design of an absorption column to absorb bromine (Br2) from air into water. Tests were made in a laboratory-packed column that is 0.1524 m in diameter, has 1.524 m of packing, and is packed with saddles. The column was operated at 20 °C and 5 atm total pressure, and the following data were obtained:
Inlet solvent is pure water.
Inlet gas is 0.02 mole frac bromine in air.
Exit gas is 0.002 mole frac bromine in air.
Exit liquid is 0.001 mole frac bromine in water.
What is the L/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 constant data are given ...
