摘要:
The present invention relates to the separation of liquid two-phase dispersions into phases and may be used in the chemical, food, and microbiological industries. An emulsion is first transformed into an aerosol with a gas as the dispersion medium and particles of the dispersion medium and dispersed phase of the initial emulsion as the dispersed phase. The resulting aerosol is then subjected to centrifugal forces, and the emulsion constituent phases are drained separately. The method may be used to break the first type emulsions or the second type emulsions. Emulsion may be aerosolized by hydraulic, or pneumatic, or ultrasonic atomizing in a gas medium. Air, or an inert gas, or nitrogen, may be used as the gas medium. The invention improves emulsion phase separation efficiency while reducing associated energy consumption.

There is provided a method of separating oil and water from a production stream, having the steps of producing a production fluid from a hydrocarbon producing well, the production fluid having a gas phase, a water phase, an oil phase, and sand phase, passing the production fluid directly from the hydrocarbon producing well through a series of separators, the series of separators having at least one water/oil separator that separates at least the water phase and the oil phase, and injecting microbubbles into the production upstream of or into the first water/oil separator relative to the hydrocarbon producing well.

摘要:
The current disclosure relates to multiphase fluid separation via a multiphase separation system. The multiphase separation system is configured to feed a multiphase fluid into feed lines within the multiphase separation system, wherein the feed lines consist of an upper line (405), a middle line (408), and a lower line (406). The upper line is configured to flow a first stream substantially including oil into an oil section of a control volume (422). The middle line is configured to flow a second stream substantially including an oil/water emulsion into an oil/water emulsion section of the control volume. The lower line is configured to flow a third stream substantially including water into a water section of the control volume. The control volume is configured to adjust fluid flow rate at an outlet (416, 420, 418), wherein the oil section, the water section, and the oil/water emulsion section each commingle at different heights of the control volume.
摘要:
A cross-linked phenolic resin demulsifier may be added to a water-in-oil emulsion having at least one foulant therein. The demulsifier may separate at least a portion of the foulant(s) from the water-in-oil emulsion, and the separated foulant(s) may be removed from the water-in-oil emulsion. In a non-limiting embodiment, the amount of the demulsifier present in the water-in-oil emulsion may range from about 0.1 ppm to about 50,000 ppm.

Processes for recovering an organic solvent extractant phase from a solid-stabilized emulsion formed in a hydrometallurgical solvent extraction circuit are disclosed. One such process includes mixing a de-emulsifier comprising an effective amount of a polymeric aggregating agent with the solid- stabilized emulsion, thereby separating the emulsion into its aqueous, organic, and solid phase components; and removing the organic solvent extractant phase from the other components, thereby recovering the organic solvent extractant phase from the solid-stabilized emulsion.
摘要:
Several prototype systems are described for separating oil and water from emulsions. The systems operate at ultrasonic resonance and are thus low power. Each system contains one or more acoustic transducers operating in the 100 kHz to 5 MHz range. Each system contains flow input for the emulsion and two or more flow outputs for the separated oil and water. Existing prototypes operate from 200 mL/min to >15 L/min. Each uses low power in the range of 1-5 W.

摘要:
A nozzle assembly and related methods for separating hydrocarbon emulsions in a fluid is provided. The nozzle assembly comprises an impingement plate into which hydrocarbon emulsions are ejected causing large emulsion particles in the fluid to be broken apart upon impact with the plate, thus allowing the various constituent components of the emulsion to be more easily separated. In certain embodiments, impact of the hydrocarbon emulsions into the impingement plate also expose clean surfaces on the various components of the emulsion fluid that can more easily interact with any surfactant that may be mixed with the fluid.
摘要:
A layer of fluoropolymer fine fiber can be made. The fine fiber can be made by electrospinning from a solvent or a solvent blend. The layers of the invention are useful in general filtration of fluid streams including gaseous and liquid streams. The fine fiber layers are also useful as hydrophobic filtration layers that can be used to separate water from a hydrocarbon stream.
