Abstract: In an embodiment, axially-fed slurry can be continuously separated into clarified liquid, stripped gas, and thickened sludge in radial counterflow between counter-rotating coaxial centrifugal impellers. One impeller comprises an annular crossflow filter through which liquids are extracted. At the periphery of the impellers, where they are narrowly separated, the sludge is shear thickened into an extruded paste. Suspended solids in the feed pass over the surface of the rotating annular crossflow filter by the shear lift effect, and the vortex-wall interaction jets water radially inward from the periphery, dewatering the sludge. Evolved gases, oils, and fractions lighter than water flow radially inward to the impeller axis through radial vortices in a shear layer between the impellers, and are extracted through an axial exhaust conduit. Feed has long residence time so that separation is complete and continuous. Municipal wastewater, produced water, beverages, food, and scrubber sludge are discussed.

Abstract: An apparatus is utilized for obtaining flow measurements from an individual oil and gas well. The apparatus utilizes pipe segments rather than vessels to separate the fluid components into a gas phase, a water phase, and an oil phase. Separation of the flow stream into the different phases allows the measurement of a particular phase. Because the oil stream may continue to contain a small amount of water, a water cut meter may be employed to determine the water content in the oil stream. The apparatus may be configured as a skid package to facilitate transportation and installation of the unit.

The water is discharged via an outlet in the lower part of the tank. The combined degassing and flotation tank is particular suited for use in oil production at sea for removal of oil and gasses from water streams before the water is returned to the sea.

The contaminated gas phase is carried out of the phase reaction chamber by a carrier air. A vacuum pump provides the low energy, high vacuum environment in the phase reaction chamber and delivers the contaminated gas phase to the condenser module for condensation providing a second change of phase.
