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.

The invention relates to a degassing vessel and related systems and methods that can remove certain gases such as carbon dioxide from a dialysis system with minimal foaming inside the degassing vessel. The invention further relates to mechanical systems and methods for degassing a dialysate or any fluid used for, during or resulting from dialysis.

An underwater facility (18) for the gas/liquid separation of a multiphase hydrocarbon mixture includes an underwater supply conduit (16) and a longitudinal separation chamber (26) intended to be installed substantially vertically, the separation chamber (26) having a lower end (30) and an opposing upper end (28), and an intermediate separation area (32), the separation chamber (26) further comprising an injection conduit (34) connected to the supply conduit (16), the injection conduit extending longitudinally into the intermediate area (32), the injection conduit having a tubular wall and a free opening that opens towards the upper end (28). The tubular wall is continuous to be impervious to the multiphase hydrocarbon mixture.

A system for removing particulate matter from a multiphase stream comprising gas, liquid and the particulate matter. The system comprises a first vessel for receiving the multiphase stream and separating a majority of gas from the multiphase stream and collecting a slurry of liquid and particulate matter; a second vessel for receiving the slurry and causing separation of the particulate matter from the liquid and for generating a pressure head of liquid against the particulate matter; a third vessel for receiving the particulate matter from the second vessel and collecting the particulate matter until a pre-determined mass or volume of particulate matter is collected; and an outlet in the third vessel for conveying the particulate matter out of the third vessel.

The present disclosure discloses an impacting T-junction component regulator for regulating components of a non-azeotropic working medium, which is formed by connecting a single T-junction or a plurality of T-junctions. Each of the T-junction comprises an inlet pipe and an outlet pipe. When the impacting T-junction component regulator is formed by a plurality of connected T-junctions, the impacting T-junction component regulator further comprises an upper manifold trunk communicated with an outlet pipe of each T-junction and throttle valves located between two adjacent T-junctions. By using the characteristics of unequal vapor and liquid components of the non-azeotropic working medium and mal-distribution of two phase flows by vertical impacting T-junctions, the regulator achieves the fluid flowing through a plurality of T-junctions and throttle valves once so as to achieve the purpose of separating components.

Integrated gas oil separation plant systems and methods are disclosed. Systems and methods include treating a crude oil inlet feed stream with a high pressure production trap (HPPT), a low pressure production trap (LPPT), a low pressure degassing tank (LPDT), a first heat exchanger, a second heat exchanger, a LPPT recycle water stream, a fresh wash water supply stream, and a LPDT recycle water stream, where the LPDT recycle water stream is operable to supply recycle water from the LPDT to an output stream from the HPPT to form the LPPT inlet feed stream.

A method to convert asphaltenes to partially oxidized asphaltenes comprising the steps of treating the reactor feed in a tubular reactor to produce a reactor effluent, introducing the reactor effluent to a disengagement zone of a vessel reactor, introducing an oxidizing agent stream to the asphaltene collection zone of the vessel reactor, reacting the asphaltenes in the asphaltene-rich fraction with oxygen from the oxidizing agent, withdrawing a bottom reactor effluent from the asphaltene collection zone, reducing a temperature of the bottom reactor effluent to produce a cooled bottom effluent, reducing a pressure of the cooled bottom effluent in a pressure regulator unit to produce a centrifuge feed, separating the centrifuge feed in a centrifuge to produce a centrate, mixing the centrate and the upper upgraded stream in a product mixer to produce a mixed upgraded stream, and separating the mixed upgraded stream in a three-phase separator.

The present invention provides a multiphase separator for separating a multiphase fluid produced by one or more oil wells, the multiphase separator comprising: a separating vessel, comprising an inlet chamber and an oil chamber for collecting oil at least partially separated by a barrier; an inlet for introducing the multiphase fluid into the separating vessel; wherein the oil chamber is positioned on the opposite side of the barrier to the inlet; a gas outlet configured to collect gas separated from the multiphase fluid; an oil outlet configured to collect oil, separated from the multiphase fluid, from the oil chamber; a water outlet configured to collect water separated from the multiphase fluid; and a gas and water mixture injector configured to inject a mixture of pressurized gas and water in a lower portion of the separating vessel.

A chemical solution feeder feeds a chemical solution to a predetermined feed target, and includes: a feed flow path that is connected at its one end to a supply source of a chemical solution at room temperature and at its other end to a feed target, to guide the chemical solution to the feed target from the supply source; a first filter that removes particles in a chemical solution at room temperature injected from the supply source into the feed flow path; a heating unit that heats the chemical solution having passed through the first filter; and a second filter that removes particles in the chemical solution at high temperature heated by the heating unit, flowing through the feed flow path toward the feed target, wherein the first filter is a hydrophilic filter and the second filter is a hydrophobic filter.

A process is presented to treat a process stream containing a hydrocarbon (oil and/or gas) and hydrogen sulfide with a liquid treatment solution containing a sulfur dye catalyst. The process stream can be within a pipeline, wellbore, subsea pipeline or a wellhead that contains hydrogen sulfide where the liquid treatment solution is injected at a predetermined point to define a scavenger zone such that the sulfur dye catalyst in the liquid treatment solution causes the sulfide from the hydrogen sulfide to react with the catalyst. The hydrocarbon component is separated substantially free of the hydrogen sulfide from a spent treatment solution containing spent sulfur dye catalyst which can then be fed to an oxidation vessel where it is contacted with an oxygen containing gas causing the sulfide to oxidize to thiosulfate and converting the spent sulfur dye catalyst to regenerated sulfur dye catalyst. The thiosulfate can be recovered, and the regenerated sulfur dye catalyst can be recycled as part of the liquid treatment solution.
