Abstract:
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.

Abstract:
The invention relates to a method for the continuous use of a vacuumized water knockout circuit integrated with a contaminated hydraulic-oil reservoir, a tank (1). A continuous process is based on a vacuum pump (12) keeping both a treatment column (8) and the tank (1) vacuumized at up to typically 98 %, contaminated hydraulic oil being pumped via the pump (3) up from the lowermost point in the inclined tank (1) through a circulation filter to a heating element (6) into the treatment column (8), where the moisture is extracted from the oil. Controlled oil flow, temperature and underpressure make water vapour be pushed continuously towards the vacuum pump (12) through a vapour cooler (13) into a condensate trap (15) which is emptied automatically via a valve (17), while gases are continuously evacuated from the vacuum pump (12) via a gas filter (18). Continuous transport of vapour out of the treatment column (8) is ensured by air being supplied via an air filter (21) through a fixed nozzle (22), while a valve (23) controls and safeguards system functions by pressure reduction and this to an atmospheric state.
Abstract:
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.
Abstract:
Process for the separation of two-phase fluids and relative accelerator unit, comprising means for pumping the two-phase fluid, at least one washing tank, filtering means for the coalescence of the particles, sensors and actuators for controlling flow rate, pressure and temperature, at least one tank for collecting the fluid at lower density (normally oil) and characterised by an oil separator inside of which a controlled field of hydrodynamic pressures is generated, correlated to the density of the fluids to be treated, which accelerates the stratification phenomenon, allowing the phase at lower density (for example oil) to be drawn off and the constant flow of the decontaminated phase (for example water) towards the outlet from the system.
Abstract:
A cavitation device is used to heat, concentrate and recycle or otherwise reuse dilute and other oil well fluids, brines and muds, and solution mining fluids, all of which commonly contain ingredients worthy of conservation. The cavitation device is powered by a Diesel engine whose exhaust may be used to heat the incoming fluid, and the product of the cavitation device is directed to a flash tank.
Abstract:
In einem Verfahren zur Aufbereitung von Öl-Wasser-Gemischen oder Emulsionen werden als Spaltstoff leicht flüchtige, flüssige Kohlenwasserstoffverbindungen, vorzugsweise aliphatischer Kohlenwasserstoff mit dem Öl-Wasser-Gemisch oder der Emulsion vermischt und das erhaltene Gemisch unter einem Druck von maximal 4,5x10 6 Pa auf maximal 130°C erwärmt, hiernach einem Absetzbehälter zugeführt, aus dem eine wasserhaltige erste Phase und eine leichtere zweite Phase aus Öl und den leicht flüchtigen Kohlenwasserstoffen abgetrennt werden. Die genannte zweite Phase kann nach bzw. durch Druckentspannung und Temperaturabsenkung in eine ölhaltige flüssige und eine gasförmige Phase aus den genannten Kohlenwasserstoffen getrennt werden. Die in Öl gebundenen feinsten Feststoffe sinken infolge der Temperaturerhöhung und Viskositätsabsenkung in die Wasserphase ab, aus der sie mittels Filtration bzw. Ultrafiltration entfernt werden können.
Abstract:
A subsea process assembly for separating a multiphase flow, the assembly comprising: an inlet for a multiphase medium; a pressure reducing means for reducing the pressure of the multiphase flow from the inlet and creating a source of energy; a multiphase separator for separating the multiphase input into individual phases; and a pumping system for, in use, pumping at least one of the desired individual phases to a delivery point by utilising at least some of the energy from the source of energy.
Abstract:
A separation system (20) and method of separating liquid components of differing densities from a liquid mixture comprising a flow conditioning apparatus and cooperating downstream separation apparatus (46).The flow conditioning apparatus includes a coalescing choke (34) having an inlet, an outlet, and a swirl chamber extending along a swirl axis. The inlet and outlet Direct the fluid mixture to flow in a circumferential direction relative to the swirl axis to create a helical flow and ideally induce coalescence of liquid droplets. The flow of the fluid mixture through the coalescing choke (34) encounters a minimum of fluid shear and associated droplet dispersion. The enhanced quality of the droplets coalesced, or at least the quantity of pre-existing droplets which are not substantially dispersed by fluid shear, increases the efficiency of liquid separation by the cooperating downstream separation apparatus (46).
Abstract:
An evaporator (1) for use in industrial waste treatment comprising: a curved pathway (8) bounded by a casing (12); an inlet port (3) through which waste fluid (7) enters the evaporator (1); a drain (4) beneath the pathway (8) through which a condensate passes, in use; and an outlet (5) through which to draw evaporated fluid. The evaporator (1) has a series of fins (6) of elongate aerofoil cross-section in the intended flow direction around the pathway (8) and, extending across the pathway (8).
Abstract:
A method, of separating oil, water and solids from oily feeds in the form of emulsions and muds is described, in which the feed has first been conditioned through pH regulation in a known manner in order to destabilise it, where the feed is first heated by being passed through an externally heated pipe. The heated feed is then led into a vacuum tank partially filled with feed that is undergoing final treatment in the form of settling, where there is a vapour pocket at the top of the tank, and where the pressure in the vacuum tank is lower than atmospheric pressure. Vapourised liquid is extracted from the vapour pocket, liquefied and treated further, while solids are allowed to settle before being removed from the bottom of the vacuum tank for further treatment, and liquid is extracted from the liquid phase for further treatment. A device for implementing the method is also described.
