A packed tower is to be designed to remove ammonia from an aqueous liquid stream by stripping with air. The entering liquid has an NH3 mole fraction of 0.0425 and a flow rate of 0.4 kmol/min; the gas is pure air, 80% of the ammonia is to be removed from the liquid. The figure below shows the equilibrium concentrations at 400 C, 1.0 atm.
Summary: This question belongs to heat transfer and discusses about a packed tower which is designed to remove ammonia from an aqueous liquid. Determines minimum gas flow rate for this situation and height and diameter needed for the column to operate at given percentage of the flooding velocity.
