Abstract
Abstract A first gaseous stream is rapidly dispersed into a second flowing gaseous stream in an inline mixing apparatus comprising a mixing zone containing (a) an inlet for the introduction into said mixing zone of the second gaseous stream at one end of the zone; (b) a gas velocity- and static pressure-stabilizing zone downstream from the inlet; (c) downstream from the gas velocityand static pressure stabilizing zone at least one sparging means having a plurality of uniformly distributed orifices on its downstream surface for the injection of the first gaseous stream into the second flowing gaseous stream, any successive sparging means having a smaller diameter than the means located upstream thereof; and (d) an outlet for the resulting mixed first and second gases from the mixing zone.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
The process of rapidly dispersing a first gaseous stream into a second stream in a mixing zone which comprises a. conveying the second gaseous stream through a 90* elbow having a radius to diameter ratio of about 1.1, b. conveying the second gaseous stream, after passage through the elbow, through a substantially cylindrical conduit having a length of from about 5 to about 7 conduit diameters, whereby substantially uniform velocity and static pressure profiles develop within the second gaseous stream; c. injecting the first gaseous stream through uniformly distributed orifices located on the downstream surface of at least one, hollow, ring-shaped sparging means into the second gaseous stream; and d. passing the mixed first and second gases from the mixing zone.
Claim 2
Dependent Claim
121 words
The process of rapidly dispersing a first gaseous stream into a second stream in a mixing zone which comprises a. conveying the second gaseous stream through a 90* elbow having a radius to diameter ratio of about 1.1, b. conveying the second gaseous stream, after passage through the elbow, through a substantially cylindrical conduit having a length of from about 5 to about 7 conduit diameters, whereby substantially uniform velocity and static pressure profiles develop within the second gaseous stream; c. injecting the first gaseous stream through uniformly distributed orifices located on the downstream surface of at least one, hollow, ring-shaped sparging means into the second gaseous stream; and d. passing the mixed first and second gases from the mixing zone.
Claim 3
Dependent Claim
128 words
An inline mixing apparatus for rapidly dispersing a first gaseous stream into a second gaseous stream which consists essentially of a mixing zone containing a. at one end of the zone, an inlet for the introduction of the second gaseous stream; b. downstream from the inlet, a resistance to the flow of the second gaseous stream, downstream of which is located a length of substantially cylindrical conduit between about 3 and about 11 conduit diameters in length; c. downstream of said length of substantially cylindrical conduit, at least one hollow, ring-shaped sparging means for injecting the first gaseous stream into the second gaseous stream; and d. an outlet for the resulting mixed first and second gaseous streams downstream from the last sparging means located within said mixing zone.
Claim 4
Dependent Claim
128 words
An inline mixing apparatus for rapidly dispersing a first gaseous stream into a second gaseous stream which consists essentially of a mixing zone containing a. at one end of the zone, an inlet for the introduction of the second gaseous stream; b. downstream from the inlet, a resistance to the flow of the second gaseous stream, downstream of which is located a length of substantially cylindrical conduit between about 3 and about 11 conduit diameters in length; c. downstream of said length of substantially cylindrical conduit, at least one hollow, ring-shaped sparging means for injecting the first gaseous stream into the second gaseous stream; and d. an outlet for the resulting mixed first and second gaseous streams downstream from the last sparging means located within said mixing zone.
Claim 5
Dependent Claim
27 words
The apparatus of claim 2 wherein the resistance to the flow of the second gas comprises an elbow having a radius to diameter ratio of about 1:1.
Claim 6
Dependent Claim
23 words
The apparatus of claim 3 wherein the elbow effects a change in the direction of flow of the second gas of about 90*.
Claim 7
Dependent Claim
23 words
The apparatus of claim 4 wherein the ring-shaped sparging means is located about 5 to about 7 conduit diameters downstream of said elbow.
