(3) FIG. 3 is a cutaway side view of the mixing element of FIG. 1 positioned within a conduit for carrying out the present mixing method.

DETAILED DESCRIPTION OF THE INVENTION

(4) Novel features which are characteristic of the invention, as to organization and method of operation, together with further objects and advantages thereof will be better understood from the following description considered in connection with the accompanying drawings, in which preferred embodiments of the invention are illustrated by way of example. It is to be expressly understood, however, that the drawings are for illustration description only and are not intended as definitions of the limits of the invention. The various features of novelty which characterize the invention are recited with particularity in the claims.

(5) There has been broadly outlined more important features of the invention in the summary above and in order that the detailed description which follows may be better understood, and in order that the present contribution to the art may be appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form additional subject matter of the claims appended hereto. Those skilled in the art will appreciate that the conception upon which this disclosure is based readily may be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important therefore, that claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.

(6) Certain terminology and the derivations thereof may be used in the following description for convenience and reference only, and will not be limiting. For example, words such as upward, downward, left, and right refer to directions in the drawings to which reference is made unless otherwise stated. Similar words such as inward and outward refer to directions toward and away from, respectively, the geometric center of a device or area and designated parts thereof.

(7) Turning first to FIGS. 1 and 2, the present element for use in a stationary material mixing and distribution device is shown. Specifically, element 10 is characterized as having web 16 extending from first end 38 to second end 39 along element longitudinal axis 5. Ramp 11 is positioned along element longitudinal axis 5 being connected to first end 38 and oriented diagonally thereto, generally at approximately 30 to element longitudinal axis 5. Ramp 11 is intended to direct a heavier fluid in an immiscible fluid stream to the center of the conduit housing element 10 for great mixing efficiency and is further characterized as having side rails 12 and 13 which act to direct fluids flowing over element 10 diagonally as provided by ramp 11. As noted particularly from FIG. 1, web 16, in moving away from first end 38 expands from relatively narrow web and 19 to expanded platform 23.

(8) Platform 23 acts to support diverter 48 positioned on a first side of expanded platform 23 and oriented diagonally thereto and second diverter 49 positioned on a second side of expanded platform and again oriented diagonally thereto. Each of the diverters comprise a pair of substantially rectangular legs 21, 22, 31 and 32 forming the diverters each of which meet at an apex (FIG. 1 illustrating apex 28), each apex being oriented toward first and 38 of web 16.

(9) In moving toward second end 39 of web 16, element 10 is further provided with first and second ears 24 and 25 bent respectively in upward and downward directions relative to longitudinal axis 5. Rectangular member 27 whose plane of orientation is substantially perpendicular to web 16 terminates element 10 noting further that third ear 26 in the plane of orientation of rectangular member 27 extends from rectangular member 27 to web 16.

(10) Element 10 is further provided with stabilizers 14, 15 and 33, the purpose of which will be more readily appreciated in reference to FIG. 3.

(11) In turning to FIG. 3, conduit 41 is shown having fluid inlet or upstream end 43 and fluid outlet or downstream end 44, the conduit characterized as having a substantially circular cross-section and a conduit longitudinal axis 7. Fluid enters conduit 41 at fluid inlet 43 in the direction of arrows 40 and exits conduit 41 at fluid exit 44 in the directions of arrows 50. Between first end 43 and second end 44 is positioned element 10 noting that element longitudinal axis 5 aligns with conduit longitudinal axis 7, first end 38 of web 16 faces fluid inlet 43 and second end 39 of web 16 faces fluid outlet 44. In doing so, stabilizers 33, 14 and 15 abut inner wall 42 of conduit 41 in order to stabilize mixing element 10 therein. To further stabilize element 10 within conduit 41 and to appropriately aid in the mixing of fluids passing there through, rectangular member 27 is sized to also abut inner wall 42 as shown. Rectangular member 27 cancels the angular rotation of fluid passing within a conduit 41 to substantially eliminate violent rotation of the fluid stream which would cause centrifuging of the fluids to occur. Typically, an automatic sampler is located two to four pipe diameters downstream of element 10 resulting in highly reliable net crude oil measurements.

(12) The above disclosure is sufficient to enable one of ordinary skill in the art to practice the invention, and provides the best mode of practicing the invention presently contemplated by the inventor. While there is provided herein a full and complete disclosure of the preferred embodiments of the invention, it is not desired to limit the invention to the exact construction, dimensions, relationships, or operations as described.

Such changes might involve alternative materials, components, structural arrangements, sizes, shapes, forms, functions, operational features or the like. Therefore, the above description and illustration should not be considered as limiting the scope of the invention, which is defined by the appended claims.
