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 for continuously removing a particular type of gas molecules (gas molecules) from a gas stream includes selecting a liquid having an affinity for the gas molecules to be removed, and providing the selected liquid to each of a first and second mat, each mat formed from a plurality of fibers having the ability to retain the selected liquid within longitudinally extending channels having longitudinally extending openings against moving into the space between the individual fibers, the mats in fluid communication therebetween with the selected liquid. The method includes directing the gas stream through a portion of the first mat into contact with the selected liquid along the longitudinally extending openings whereby the selected liquid absorbs the gas molecules, and directing a second gas through a portion of the second mat so that the gas molecules, absorbed by and disbursed throughout the selected liquid, are stripped and carried away.

The present invention relates to a degassing system (1, 23) with a control device (17, 36), a degassing tank (2, 24) with a first space area (3, 25) configured for having liquid introduced therein and a second space area (4, 26) configured for having the liquid from the first space area (3, 25) introduced therein. The first and the second space area are partially separated from one another by a separation element (5, 27). A controllable pump (15, 34) is provided, which pumps liquid from the first space area to the second space area for a two-stage vacuum degassing process, when the pump is operated. The control device controls the pump such that the pump will not be operated for a single-stage vacuum degassing process and will be operated for a two-stage vacuum degassing process. Furthermore, the present invention relates to a method of executing a degassing process of a liquid making use of a degassing system according to the present invention. In addition, the present invention relates to a beverage treatment machine comprising the degassing system and a filling plant arranged downstream of the degassing system.

This gas-liquid separator is provided with: a tank part which stores and separates a refrigerant; and a pipe connection part forming outlet/inlet ports for the refrigerant from the tank part. The pipe connection part has: a first connection part having a first connection pipe which guides the refrigerant to an expansion valve; a second connection part having a second connection pipe through which the cooled refrigerant returns; a third connection part having a third connection pipe which guides the refrigerant to a compressor; a fourth connection part having a fourth connection pipe which guides the refrigerant into the tank part from an outdoor heat exchanger; and a first flow path switching valve which allows the inside of the tank part to communicate with the third connection pipe during heating operations, and allows the second connection pipe to communicate with the third connection pipe during cooling operations.

The present system is for integrated management of associated gas and produced water at oil well extraction sites. The system includes a controller that makes gas allocation determination (e.g., directs conditioned gas to (i) gas flare, (ii) produced water reduction system, and/or (iii) generator) when a change in conditioned gas flow is detected based on first plurality of inputs. If the conditioned gas is directed to the generator, then the controller makes an electricity allocation determination (e.g., (i) increase a data processing operating rate on a data processing server, (ii) start up idle data processing equipment, (iii) direct generated electric current to a power grid, and/or (iv) charge a storage battery) based on second plurality of inputs. By operating the system of gas consumption and electricity production/consumption in an integrated fashion, benefits of flaring prevention, resource conversation, and more efficient economic operations are optimized to a degree not previously attainable.

The degassing system can include a degassing vessel and can utilize a vacuum pump and a fluid pump located downstream of the degassing vessel to control the pressure within the degassing vessel in order to control the concentration of gases in fluid exiting the degassing system. The degassing system can further comprise sensors in communication with the pumps to control the rate of flow and pressure through the degassing system. The degassing system may be placed in a dialysate flow path to remove dissolved gases including carbon dioxide from the dialysate.

A submersible fluid system for operating submersed in a body of water includes an electric machine and a fluid-end. The fluid-end includes a fluid-end housing having an inlet to a fluid rotor, the fluid rotor coupled to the electric machine and carried to rotate in the housing by a bearing in the housing. A fluid separator system receives a multiphase fluid and communicates a flow of the fluid to the inlet and a substantially liquid flow extracted from the multiphase fluid to the bearing.

Apparatuses, systems, and methods for transferring fluid to a stage in a charged particle beam system are disclosed. In some embodiments, a stage may be configured to secure a wafer, a chamber may be configured to house the stage; and a tube may be provided within the chamber to transfer fluid between the stage and outside of the chamber. The tube may include a first tubular layer of first material, wherein the first material is a flexible polymer; and a second tubular layer of second material, wherein the second material is configured to reduce permeation of fluid or gas through the tube. In some embodiments, a system may include a degasser system outside of the chamber, where the degasser system may be configured to remove gases from the transfer fluid before the transfer fluid enters the tube.

The invention relates to an apparatus having a pressure chamber and a micropump in fluid connection with the pressure chamber. The pressure chamber includes a gas-carrying region and a liquid-carrying region. The micropump is configured to generate a pneumatic pressure within the gas-carrying region that is lower than a fluid pressure of a liquid flowing through the liquid-carrying region. According to the invention, a gas-permeable and liquid-impermeable separating element separates, at least in sections, the gas-carrying region and the liquid-carrying region. According to the present invention, the micropump is disposed on the pressure chamber.

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.
