A method, device and a system for extracting oil from a paste of oily fruit by exposing the oily fruit paste to vacuum.

The invention relates to a device and to a method for separating two immiscible fluids (2, 3), wherein a three-phase system is formed with a Winsor III type bicontinuous phase (4) so as to phagocytize the dispersed droplets and to produce a droplet-free liquid (2).

A water treatment system and method. Influent water produced from an oil and gas production or the like is circulated in a multistage unit where the water is treated by degassing the water by saturating the water with air, stripping volatile compounds from the water, evaporating non-aqueous phase liquid petroleum from the water, repeatedly stripping and equilibrating inorganic carbons in the water, subliming semi-solids from the water, and breaking colloids in the water using continuous cavitation. Water from the multistage unit is clarified through floatation and sedimentation and biological material in the water is inactivated using irradiation. Water is then filtered before being provided as treated water for an application specific process such as electro desalination reversal, fracking reuse, or other wastewater recovery.

A scum removal system for use with a wastewater treatment clarification tank containing wastewater is provided and includes a debris intake conduit, a debris discharge conduit, and a pump article. The pump article is configured to be in flow communication with the debris intake conduit and the debris discharge conduit, wherein the pump article and debris intake conduit are configured to generate a suction within the debris intake conduit and wherein the debris intake conduit is configured to be located proximate the wastewater. Additionally, the debris intake conduit is sloped downwardly at a debris intake conduit angle β, and the second discharge conduit is sloped downwardly at a debris discharge conduit angle Ω.

A method of producing a product oil stream comprising the steps of mixing the liquid product in the product mixing tank for a mixing residence time to produce a mixed liquid product, maintaining the mixed liquid product in the product separation tank for a separation residence time, separating upgraded hydrocarbons from the mixed liquid product in the product separation tank, where the separation residence time allows the upgraded hydrocarbons to separate from and float on top of a water layer in an inlet section of the product separation tank, operating the product separation tank such that the upgraded hydrocarbons flow over a weir, the weir configured to separate the inlet section from an oil collection section, withdrawing the product oil stream from the oil collection section, where the product oil stream comprises upgraded hydrocarbons, and withdrawing a spent water from the inlet section of the product separation tank.

A method of extraction of a liquid hydrocarbon fraction from carbonaceous waste feedstock. Waste material is slurried, by grinding or comminution of same into a substantially uniform stream of around waste material. Fluid would be added as required to supplement the ground waste to yield a slurry of desirable parametersthe fluid used would be primarily liquid effluent fraction recovered from previous operation of the method. Feedstock slurry is placed into a pressurized heat transfer reactor where it is maintained at temperature and pressure for a predetermined period of time. On discharge from the heat transfer reactor the processed emulsion is separated into liquid hydrocarbon fraction, liquid effluent fraction and solid waste fraction. A novel heat transfer reactor design is also disclosed.

Systems and methods for separation of hydrocarbon containing fluids are provided. More particularly, the disclosure is relevant to separating fluids having a gas phase, a hydrocarbon liquid phase, and an aqueous liquid phase using indirect heating. In general, the system uses a first three-phase gas separation. The gas stream separated out is cooled with the resulting hydrocarbon condensates reintroduced to the stream of hydrocarbon-liquid phase that was separated from the fluid. The resulting combined stream can be cooled or heated as necessary.

An axial flow-type pump apparatus with magnetic bearings for separating immiscible flowable materials having different specific gravities and a discharge manifold connected to the fluid pump for drawing off the flowable separated materials with greatly improved efficiency, and pump and apparatus longevity.

A method of separating hydrocarbons from an oil field production stream may include providing a production stream having a gas phase and a liquid phase, the production stream including oil, hydrocarbon gas, carbon dioxide, and water; substantially separating the gas phase from the liquid phase; separating the liquid phase into a stream composed substantially of oil and a stream substantially composed of water, the stream substantially composed of water containing carbon dioxide absorbed therein; pressurizing the water stream containing carbon dioxide absorbed therein; and injecting the pressurized water stream containing carbon dioxide absorbed therein to a downhole injection location; the method may include operating each step at a pressure above 150 psig.

A system having improved trapping force for acoustophoresis is described where the trapping force is improved by manipulation of the frequency of the ultrasonic transducer. The transducer includes a ceramic crystal. The crystal may be directly exposed to fluid flow. The crystal may be air backed, resulting in a higher Q factor.
