An oil reservoir assembly includes a tank, a return passage, a pressurization valve, a first passage, and a vent valve. The tank includes a canister, a fill port, an first oil outlet, an second air outlet, and an inlet. The inlet is disposed in the canister and is connected to a restrictor. The return passage is connected to the inlet of the tank and to a scavenge pump. The pressurization valve is fluidly connected to the second air outlet of the tank. The first passage is connected to the pressurization valve and to an accessory gearbox of the engine. The vent valve is disposed in the return passage and includes a body, a channel extending through the body, an inlet orifice, and an outlet orifice. The inlet orifice is disposed in an end of the body. The outlet orifice is fluidly connected to the inlet orifice via the channel.

A debubbler system includes a hollow enclosure that includes an inlet and an outlet directing the flow of coolant fluid into and out from the hollow enclosure, respectively. The debubbler system further includes a check valve to exhaust gaseous bubbles in the coolant fluid out of the hollow enclosure to reduce the gaseous bubbles in the coolant fluid. The debubbler system also includes a vent tube fluidly coupled to the check valve, such that the vent tube is positioned opposite a weighted member that is fixed relative to a central axel that rotates about a rotation axis. The debubbler system may be part of a cooling system for cooling electronics systems, such as light-emitting diode (LED) lighting systems.

An electric submersible pump assembly with integral heat exchanger, high speed gas separator, high-speed self-aligning bearings, and dual bearing thrust chamber is described. The described gas separator may be used for operating an electric submersible pump at high speeds as well as over a wide range of speeds and flowrates without replacing downhole equipment.

A continuous-feed vacuum distillation system with an integrated degasser is proposed. The degasser uses the same or a different vacuum system as the downstream distillation column and operates continuously on the material to be distilled before it enters the distillation column. This eliminates the current practices of degassing the feed material in bulk, with auxiliary equipment, before it enters the distillation apparatus, a difficult and time-consuming procedure, or using the distillation system in a low temperature state under vacuum, to remove the gas from the feed material, which is also inefficient. Various alternative features of the claimed integrated degasser are also claimed.

Techniques for improving a drilling fluid flow rate of a drilling fluid degasser by splitting the flow of the drilling fluid (e.g., drilling mud) are provided. An exemplary apparatus for degassing drilling fluid generally includes a pressure vessel; a vacuum blower in fluid communication with the pressure vessel; a slotted centrifuge tube having a cross-sectional area; a motor configured to power the vacuum blower and rotate the slotted centrifuge tube; an evacuation pump having an impeller connected with a lower end of the slotted centrifuge tube; and an inlet pipe spaced a distance away from the lower end of the slotted centrifuge tube, wherein the distance is based on a relationship between a cross-sectional area of the inlet pipe and the cross-sectional area of the slotted centrifuge tube.

A device and method for scrubbing an absorbate from a gas is described. The rotational absorber device comprises a housing having a gas inlet, a gas outlet, an absorbent liquid inlet and an absorbent liquid outlet; a rotor mounted for rotation in said housing and connecting to the inlets and outlets, the rotor comprising a plurality of scrubbing channels extending axially and parallel to a common rotation axis; and means for rotating the rotor. The device and method provide a scrubbing of the gas with improved selectivity and efficiency.

A device for gas-liquid separation, intended to equip three-phase fluidized bed reactors such as those used in the H-oil process. The device has a succession of two bends situated in different planes, which device accomplishes excellent separation of the gas and of the liquid.

A turbine having a turbine wheel, as used for example as a drive for active oil separators, and to a liquid separator using the turbine is described.

A method for producing a sealant includes a weighing and mixing step, a kneading step, a stirring and defoaming step, and a filling step. In the weighing and mixing step, a main component and a curing agent are weighed and mixed together. In the kneading step, the mixture mixed in the weighing and mixing step is kneaded. In the stirring and defoaming step, the kneaded product kneaded in the kneading step is stirred and defoamed. In the filling step, the kneaded product defoamed in the stirring and defoaming step is filled into a container. In the stirring and defoaming step, the kneaded product is stirred under a condition wherein a stirring rotational speed at which the kneaded product is stirred and a stirring time for which the kneaded product is stirred are within a range from an arithmetic product lower limit value to an arithmetic product upper limit value.

A reverse flow gas separator having a housing having a housing intake and a first void space within the housing. The reverse flow gas separator further includes a driveshaft disposed adjacent to the first void space. The drive shaft is hollow and comprises a second void space disposed within the interior of the drive shaft. The second void space is continuous from a driveshaft intake to an opening in a terminal end of the driveshaft.
