Abstract: An eductor apparatus has an inlet nozzle section with a primary inlet and a nozzle, a mixing chamber connected to the inlet nozzle section and in fluid communication with a narrow diameter opening of the nozzle, and a diffuser section connected to the mixing chamber opposite the inlet nozzle section. The diffuser section has throat formed therein. The throat has a plurality of lobes formed thereon. The plurality of lobes extend longitudinally along the throat. The lobes are generally equally circumferentially spaced from each other around the throat. The narrow diameter opening of the nozzle has another plurality of lobes formed therearound and extending in longitudinally alignment with the plurality of lobes of the throat.

Abstract: The invention relates to a floating suction device for a pump wherein the pickup point for the pump suction can be adjusted to various elevations. An aeration feature may be combined with the floating suction device to sparge compressed gas into an oil/hydrocarbon layer to promote movement of hydrocarbons from that layer into a topmost hydrocarbon rich layer for ultimate pumping through the floating suction device.
