Abstract
Abstract A method and apparatus are provided for mixing a fluid traveling in a pipe section with a second fluid introduced into the pipe section by sparging the second fluid into the pipe section at points across the internal diameter of the pipe section, disrupting the flow through the pipe section with a perforated frusto-conical baffle coaxially aligned with the pipe section with its apex extending toward the means of sparging the second fluid, sparging additional second fluid downstream from within the throat of the frusto-conical baffle, and disrupting the flow within the pipe downstream of the frusto-conical baffle and sparging means with a line restriction extending from the pipe section sidewalls into the pipe section to create an orifice of smaller diameter than the pipe section inside diameter coaxially aligned with the pipe section.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
154 words
An apparatus for mixing a first fluid stream with a second fluid stream being carried in a pipe section said apparatus comprising: a. an elongated sparging pipe means extending into said pipe section across the internal diameter of said pipe section, said sparging pipe means perforated to emit a flow of sparged fluid at points spaced across the internal diameter of the pipe section, said elongated sparging pipe means also having on the downstream side, alIgned coaxially with the pipe section, a teed portion perforated to emit a flow of sparged fluid, b. a perforated frusto-conical baffle means surrounding said teed portion, said baffle means coaxially aligned with the pipe section with the apex of the baffle extending toward said elongated sparging means, and c. downstream of the baffle a restriction extending around the pipe section interior sufficiently restricting flow along the pipe wall to disrupt the pattern of flow in the pipe section.
Claim 2
Independent Claim
154 words
An apparatus for mixing a first fluid stream with a second fluid stream being carried in a pipe section said apparatus comprising: a. an elongated sparging pipe means extending into said pipe section across the internal diameter of said pipe section, said sparging pipe means perforated to emit a flow of sparged fluid at points spaced across the internal diameter of the pipe section, said elongated sparging pipe means also having on the downstream side, alIgned coaxially with the pipe section, a teed portion perforated to emit a flow of sparged fluid, b. a perforated frusto-conical baffle means surrounding said teed portion, said baffle means coaxially aligned with the pipe section with the apex of the baffle extending toward said elongated sparging means, and c. downstream of the baffle a restriction extending around the pipe section interior sufficiently restricting flow along the pipe wall to disrupt the pattern of flow in the pipe section.
Claim 3
Dependent Claim
33 words
The apparatus of claim 1 wherein the elongated sparging pipe means is perforated to emit a flow of sparged first fluid perpendicular to the flow of the fluid flowing within the pipe section.
Claim 4
Dependent Claim
72 words
The apparatus of claim 1 wherein the frusto-conical baffle has an angle of the cone of 30* to 60*, the cone is attached to a nipple up to 10 pipe diameters of the sparger pipe in distance from the sparger pipe, and the distance from the downstream end of the perforated cone to the restricting orifice is from one to five diameters of the pipe section through which the fluids are flowing.
Claim 5
Dependent Claim
31 words
The apparatus of claim 3 wherein the angle of the cone of the frusto-conical baffle is 45* and the base of the cone is immediately attached to the elongated sparger pipe.
Claim 6
Dependent Claim
58 words
The apparatus of claim 4 for mixing sparged butene feed with a steam-air mixture passing through a nominal 24 inch pipe section wherein the sprager pipe is a nominal 6 inch pipe section and the restriction is a 1 foot 5 1/4 inch orifice port located 2 1/2 feet downstream from the open bell of the frusto-conical baffle.
Claim 7
Independent Claim
126 words
A method for mixing a first fluid with a second fluid stream being carried in a pipe section, said method comprising: a. sparging said first fluid into said second fluid at points across the internal diameter of the pipe section perpendicular to the second fluid flowing in the pipe section, b. interrupting the flow of said first and second fluids with a perforated frusto-conical baffle means coaxially aligned with the pipe section with the apex extending toward means for sparging the first liquid into the pipe section, c. introducing additional sparged first fluid downstream within the bell of the frusto-conical baffle means and d. interrupting the fluid flow within the pipe section by means of restrictive orifice downstream of the bell of the frusto-conical baffle means.
Claim 8
Independent Claim
126 words
A method for mixing a first fluid with a second fluid stream being carried in a pipe section, said method comprising: a. sparging said first fluid into said second fluid at points across the internal diameter of the pipe section perpendicular to the second fluid flowing in the pipe section, b. interrupting the flow of said first and second fluids with a perforated frusto-conical baffle means coaxially aligned with the pipe section with the apex extending toward means for sparging the first liquid into the pipe section, c. introducing additional sparged first fluid downstream within the bell of the frusto-conical baffle means and d. interrupting the fluid flow within the pipe section by means of restrictive orifice downstream of the bell of the frusto-conical baffle means.
