Abstract:
1. A mixing apparatus for reacting a gas in a liquid medium, comprising (a) a substantially cylindrical vessel having a substantially horizontal axis and containing the liquid medium, (b) an inlet port at a first axial end of the vessel for introducing a feed gas into the vessel, (c) an outlet port at a second axial end of the vessel for removing an effluent gas from the vessel, (d) a plurality of sequential mixing zones spaced along the axis of the vessel in each of which zones the feed gas is mixed with the liquid medium, and (e) an impeller assembly in each mixing zone that imparts a radial and circumferential motion to the feed gas, and entrains the feed gas in the mixing zone until it is displaced therefrom by incoming feed gas or by feed gas displaced from the previous mixing zone.
