Provided is an UFB generating apparatus and an UFB generating method capable of efficiently generating an UFB-containing liquid with high purity. To this end, the ultrafine bubble generating apparatus includes a pre-processing unit that performs predetermined pre-processing on a liquid W and a generating unit that generates ultrafine bubbles in the liquid on which the pre-processing is performed. The generating unit generates the ultrafine bubbles by causing a heating element, which is provided in the liquid on which the pre-processing is performed, to generate heat to generate film boiling on an interface between the liquid and the heating element.

A dilute chemical solution producing apparatus includes, in a supply line of ultrapure water, a platinum group metal carrying resin column, a membrane-type deaeration apparatus, and a gas dissolving membrane apparatus, and a washing chemical solution injection apparatus is provided between the platinum group metal carrying resin column and the membrane-type deaeration apparatus. An inert gas source is connected to a gas phase side of the membrane-type deaeration apparatus, and an inert gas source is also connected to a gas phase side of the gas dissolving membrane apparatus. A discharge line communicates with the gas dissolving membrane apparatus. With such a dilute chemical solution producing apparatus, a dilute chemical solution with both dissolved oxygen and dissolved hydrogen peroxide being removed can be safely produced and supplied in a washing step for semiconductor washing.

A flow back system for separating solids from a slurry recovered from a hydrocarbon well. The system includes a V-shaped tank with a first series of baffles configured to cause the settling of solids that are moved by a shaftless auger to a conduit fluidly connected to hydrocyclones mounted over a linear shaker. The overflow from the hydrocyclones is discharged through a second conduit back into the tank for processing by a second series of baffles resulting in a clean effluent. The clean effluent is recirculated in the well.

A gas turbine engine has a fan drive turbine for driving a gear reduction. The gear reduction drives a fan rotor. A lubrication system supplies oil to the gear reduction, and includes a lubricant pump to supply an air/oil mixture to an inlet of a deaerator. The deaerator includes a separator for separating oil and air, delivering separated air to an air outlet, and delivering separated oil back into an oil tank. The separated oil is first delivered into a pipe outwardly of the oil tank, and then into a location beneath a minimum oil level in the tank. Air within the oil tank moves outwardly through an air exit into the deaerator. A method of designing a gas turbine engine is also disclosed.

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.

An electrohydraulic system includes a hydraulic load and at least one closed hydraulic circuit. The hydraulic circuit includes at least one control mechanism, a hydraulic machine, and a closed hydraulic reservoir. The closed hydraulic circuit is filled with degassed hydraulic fluid. A method, in one embodiment, includes filling the electrohydraulic system with degassed hydraulic fluid. In one embodiment, equipment is provided for filling the electrohydraulic system with the degassed hydraulic fluid

The present invention relates to a gas/liquid separator. According to an aspect of the present invention, provided is a gas/liquid separator, including a housing including a first supply part and a second supply part; a rotary shaft rotatably provided to the housing; a drive unit configured to rotate the rotary shaft; fixed cones disposed in an interior of the housing and each including a tilted area, diameters of which are decreased in a direction from the first supply part to the second supply part, a first through-hole, which passes the rotary shaft, and at least one second through-hole, through which a second fluid introduced via the second supply part passes; and rotary cones disposed in an interior of the housing so as to be spaced apart from the fixed cones and installed at the rotary shaft so as to rotate about the rotary shaft.

A cyclonic inlet diverter for initiating the separation of a multi-phase inlet fluid flow comprises an enclosed tubular body mounted crosswise within a larger separator vessel. The inlet diverter includes a splitter plate positioned within a center portion of the tubular body and configured to split the inlet flow into a first stream and a second stream, and a swirl plate positioned on each side of the splitter plate with angled surfaces configured to increase the cyclonic motion of the first and second streams within the tubular body. The inlet diverter further includes elongate apertures formed through bottom sidewall portions of the tubular body on each side of the splitter plate, an axial aperture formed through opposing end caps of the tubular body, and at least one radial aperture formed through lateral sidewall portions of the tubular body proximate each opposing end cap.

Techniques and apparatus for separating a Flowback mixture received from a wellbore. Employing a vessel or system of vessels to receive the fluid mixture and configured to manage the discharge of gases, liquids, and solids to maintain a vapor barrier in the vessel(s) to prevent unwanted release of gas to the atmosphere.

The present disclosure relates to a multi-effect desalination apparatus by partially dosing acids into only evaporators corresponding to a relatively high temperature part, while dosing a polymer-based anti-scalant into all the evaporators, to minimize a risk of a scale and corrosion with maximizing a top brine temperature of desalination facility, and a desalination method using the same.
