An apparatus for dispersing a gas into a fluid stream. The apparatus has a generally annular body disposed to define an orifice in the fluid stream, a plurality of inwardly depending apertures formed in the body and in fluid communication with a supply of pressurized gas. Each of the apertures defines a localized injection point for dispersion of the pressurized gas into the fluid stream. The orifice includes a restricted throat section adapted to progressively reduce the effective cross-sectional flow area of the fluid downstream of the apertures, such that resultant velocity and pressure differentials enhance dissolution of the gas in the fluid.

[ We claim:] [1.] An apparatus for dispersing a gas into a fluid stream flowing through a conduit comprising a generally annular body disposed to define an orifice in the fluid stream, said orifice including a restricted throat section adapted to progressively reduce the effective cross-sectional flow area of the fluid from the cross-sectional area of the conduit to the cross-sectional area of a neck portion downstream of said throat section, and a plurality of inwardly depending apertures formed in said throat section in fluid communication with a supply of pressurised gas, each of said apertures defining a localised injection point for dispersion of the pressurised gas into the fluid stream upstream of said neck portion, whereby the resultant velocity and pressure differentials in the fluid upstream and downstream of said neck portion enhance dissolution of the gas therein.
