Abstract:
An apparatus for providing a large interfacial contact area between one or more liquids and one or more gases to provide a gas-in-liquid emulsion, comprising:two cylindrical members mounted for rotation relative to one another, and having opposing surfaces spaced to form an annular processing chamber therebetween providing a flow path for the liquid and gas; and wherein: the annular processing chamber has a gap distance defined by a distance between the opposing surfaces; the cylindrical members rotate relative to each other at a relative rotation rate; the gap distance being approximately equal to or less than the back-to-back radial thicknesses of two laminar boundary layers provided by said one or more liquids and one or more gases and relative rotation rate are such as to form a gas-in-liquid emulsion of the one or more gases in the one or more liquids.
