Abstract
Abstract A distributor for introduction of mixed gas and liquid into a vessel which provides improved mixing of the vessel''s contents and intimate contact between the gas and liquid by formation of small gas bubbles. Two phase flow is baffled to assure a uniform dispersion of liquid in gas prior to sparging the mixture into the vessel. Sparging takes place at high velocities to provide a multiplicity of small gas bubbles created by the shearing action of the liquid passing through the openings in the sparger.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
39 words
The distributor of claim 1 wherein said baffle means comprise an annular member extending transversely to the inner walls of said conduit and acting to force liquid flowing through said conduit to mix with gas flowing in said conDuit.
Claim 2
Dependent Claim
53 words
The distributor of claim 1 wherein said sparger means comprise a plurality of concentric ring passageways having uniformly distributed openings located facing into said vessel and characterized by a high resistance to the flow of gas and liquid thereby creating a multiplicity of small gas bubbles and providing mixing of the vessels contents.
Claim 3
Dependent Claim
32 words
The distributor of claim 1 wherein said baffle means are located a distance between about 1 and about 2 times the diameter of said inlet conduit upstream of the said sparger means.
