Mixer embodiments include a body having a cone shaped leading edge and a hemi-spherical end. Other embodiments include a double cone having a series of helical fins on the trailing end of the double cone and fins extending perpendicular to the pipeline axis having a triangular cross section. The fins may be staggered with a mix of vertically and horizontally orientations. | 06-04-2009 |
| 20090242178 | Raised overlapped impingement plate - A heat exchanger for transfer of heat from a first fluid to a second fluid, including: a housing defining an interior space, a plurality of tubes spaced apart from each other, fixed in the housing, and extending in a first direction within the interior space, a first inlet for receiving the first fluid into and through the tubes, and first outlet for discharging the first fluid out of the tubes, a second inlet for receiving the second fluid into the interior space in an inlet flow direction generally transverse of the first direction, and a second outlet for discharging the second fluid out of the interior space, and an impingement plate assembly situated in the interior space of the housing between the second inlet means and the plurality of tubes, with a fouling area defined as the area in the interior space that includes portions of the tubes directly beneath said impingement plate assembly, the impingement plate assembly including: (a) a top plate facing the second inlet, where the top plate lies in a plane generally transverse to the inlet flow direction and onto which the second fluid flow impinges, and (b) a bottom plate fixedly spaced from and generally parallel to and overlying the top plate, the bottom plate defining therethrough an aperture extending from top to bottom thereof. | 10-01-2009 |
| 20110240278 | Plug Kit for Pressured Components - An apparatus for plugging a bore of a tube sheet, the apparatus includes cantilevered members that project radially outward from a body on the inner surface of the tube sheet. Slots can be drilled into a tube the projects into the bore and the cantilevered members set into the slots. The cantilevered members can slide radially outward from within the body, or can be pivotingly attached on an end of the body. One end of a bolt threadingly attaches to the body, and attaches on its other end to a nut circumscribing the tube sheet bore on its outer surface. A deformable collar circumscribes the bolt between the body and nut and provides a seal within the tube sheet bore. The apparatus can also be used to plug bores that do not include tubes. | 10-06-2011 |

| 20110240272 | ASSEMBLY FOR PLUGGING A TUBE - A device and method for plugging a tube that includes setting a tapered plug in a tube with a compression ring that circumscribes the plug. The ring radially expands when axially compressed and wedges the plug in the tube. An anchoring assembly fits over the tapered end of the plug and is coupled to the plug while being pushed against the compressed ring. When coupled to the plug, the anchoring assembly maintains the ring in a compressed state. The anchoring assembly can be made up of legs that fasten to the tapered end of the plug and have shoulders attached on a free end that are positioned against a lateral side of the compressed ring. | 10-06-2011 |

| 20110315600 | REMOVAL OF SULFUR COMPOUNDS FROM PETROLEUM STREAM - A process for upgrading an oil stream by mixing the oil stream with a water stream and subjecting it to conditions that are at or above the supercritical temperature and pressure of water. The process further includes cooling and a subsequent alkaline extraction step. The resulting thiols and hydrogen sulfide gas can be isolated from the product stream, resulting in an upgraded oil stream that is a higher value oil having low sulfur, low nitrogen, and low metallic impurities as compared to the oil stream. | 12-29-2011 |

| 20110226455 | Slotted impingement plates for heat exchangers - Impingement plates for shell and tube heat exchangers are positioned between the inlet openings and the tubes with the surfaces of the impingement plates being normal to the flow path of the liquid entering the shell from the inlet openings and having a plurality of openings through which a portion of the liquid passes before contacting the tubes. The openings can be formed as elongated parallel slots that are positioned parallel to the tubes and function to enhance the fluid flow, especially in the area that is immediately downstream from the impingement plates, thereby reducing fluid stagnation, fouling and tube erosion and prolonging the useful life and time in service between maintenance shut downs. | 09-22-2011 |

| 20110253341 | AUXILIARY SUPPORTS FOR HEAT EXCHANGER TUBES - A method of manufacturing or modifying a tube set for a bundled tube heat exchanger, and corresponding apparatus, is provided. An elongated support member is attached to baffles in a heat exchanger. The elongated support member has opposed contoured tube-contacting surfaces and face contact surfaces. The opposed contoured tube-contacting surfaces receive, in close-fitting relation, the exterior surface of a portion of adjacent rows of tubes passing through baffle apertures. The elongated support member is positioned so that its face contact surface is adjacent to a face surface of the baffle, and the opposed contoured tube-contacting surfaces are adjacent to the exterior surfaces of the plurality of tubes. The elongated support member is attached, e.g., by welding, to the face surface of the baffle, in a manner that does not interfere with the operation of the heat exchanger. | 10-20-2011 |
