Abstract: In a method and apparatus for treating fluids, a pump delivers a fluid flow from a fluid source to a manifold. The manifold divides the fluid flow into first and second fluid flows, which are delivered from the manifold to a housing. The housing includes therein a first vortex nozzle positioned in opposed relationship to a second vortex nozzle. The first fluid flow enters the first vortex nozzle to create a first rotating fluid flow, and the second fluid flow enters the second vortex nozzle to create a second rotating fluid flow. The first and second vortex nozzles impinge the first and second rotating fluid flows in a collision chamber, thereby treating the fluid.

Abstract: Submerged jet nozzles are located at equal distances from the center of a tank containing a quantity of liquid and solids. Some of the nozzles induce flow partly inward and some induce flow partly outward, but all mixers are directed generally in the same circumferential direction. The inward directed nozzles are located close to the bottom of the tank and direct liquid across the central portion of the tank where solids tend to accumulate. Upper nozzles direct flow at least partly outward but in the same circumferential direction as the lower nozzles. The flow from the upper nozzles tends to reflect off the wall of the tank in addition to inducing a rotational flow of substantially the entire body of liquid in the tank.

Abstract: A uniform small particle homogenizer for liquid product comprising a pair of intensifier cylinder pumps (20) driven by a hydraulic system (22). The pumps have a power stroke side and a suction stroke side, and a pair of proximity sensors (24) that interface with each pump to detect forward and rearward movement. A microprocessor (26) with timing capabilities controls the sequential operation of each pump with the power stroke of each pump timed to alternately produce a flow of the liquid product with a precisely timed flow overlap period from the alternating pumps. Since the power stroke takes a longer time than the suction stroke, the instant each power stroke is started the opposite pump is timed to hesitate and slightly overlap until a constant product flow-rate is produced from the alternating pumps, which eliminates large variances in pressure and therefore achieves uniformity in product particle size.

The injected liquid is crude oil or a refinery product and differs from the lowest levels above the sediment in that it comprises a smaller share of heavy components.
