ABSTRACT:
A vessel is adapted to contain a liquid phase and a tubular guide baffle in the vessel has spaced open ends one of which at least in part bounds a venturi-shaped passage. A rotary impeller in the vessel has an axial inlet communicating with the one open end and a plurality of peripheral outlets which communicate with the axial inlet. A drive is provided for rotating the impeller so that centrifugal action causes expulsion of liquid phase from the outlets and thereby creates suction in the venturi-shaped passage to draw additional liquid phase from the guide baffle into the inlet. Gas admitting arrangements are provided, including a plurality of nipples communicating with the passage and with a conduit through which gas is supplied, so that the suction in the venturi-shaped passage draws gas from the source via the conduit and the nipples and the gas becomes admixed with the liquid phase.
