Abstract
Abstract A liquid stream is caused to disintegrate in a spray of fine droplets, thereby markedly increasing the amount of surface area available for reaction. The liquid is forced through an orifice into a chamber of lower pressure; prior to its entrance into the chamber, fine bubbles of a gas are entrained within the liquid. After entry into chamber, the individual bubbles expand radially, causing the stream to be broken into sheets of fine droplets, which then react with a gas or liquid in the chamber and/or with injected gas.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
36 words
The method of claim 1, wherein said point of injection is sufficiently proximate said nozzle, so as to cause a major portion of said bubbles to be entrained within the increment of liquid entering said nozzle.
Claim 2
Dependent Claim
13 words
The method of claim 2, in which said reactant fluid is a gas.
Claim 3
Dependent Claim
24 words
The method of claim 3, in which the surface of liquid available for reaction is increased, by increasing the flow rate of injected gas.
Claim 4
Dependent Claim
23 words
The method of claim 4, in which the surface of liquid available for reaction is increased, by decreasing the radius of injected bubbles.
Claim 5
Dependent Claim
34 words
The method of claim 5, in which the surface of liquid available for reaction is increased, by increasing the pressure in said containment vessel, in relation to the pressure in said low pressure zone.
Claim 6
Dependent Claim
16 words
The method of claim 6, in which said additional force is supplied by a mechanical piston.
Claim 7
Dependent Claim
14 words
The method of claim 6, in which said additional force is that of gravity.
Claim 8
Dependent Claim
16 words
The method of claim 8, in which said injected gas is other than said reactant gas.
Claim 9
Dependent Claim
23 words
The method of claim 9, in which the concentration of reactant gas is maintained by a bleed of said gas into said zone.
Claim 10
Dependent Claim
14 words
The method of claim 8, in which said injected gas contains said reactant gas.
Claim 11
Dependent Claim
24 words
The method of claim 11, in which the concentration of reactant gas is augmented by an additional bleed of said gas in said zone.
Claim 12
Dependent Claim
21 words
The method of claim 8, in which said liquid is molten iron and said gaseous reactant is an oxygen containing gas.
Claim 13
Dependent Claim
21 words
The method of claim 13, in which said components are impurities which are removed by reaction with said oxygen containing gas.
