An apparatus for degassing of gaseous components from at least one curable material, particularly a curable material for building a composite part, for example, a rotor blade for a wind turbine, is provided in an embodiment herein. The apparatus includes at least one degassing chamber having at least one inlet for introducing a curable material for building a composite part, the curable material containing gaseous components into the degassing chamber and at least one outlet for removing a degassed curable material from the degassing chamber and at least one mechanical splitting means adapted to mechanically split up gaseous components contained within the curable material so as to release the gaseous components from the curable material.

An aircraft fuel deoxygenation system includes a boost pump, a contactor-separator, and a centrifuge-separator pump. The boost pump is adapted to receive fuel from a fuel source and inert gas from an inert gas source, and is configured to mix the fuel and inert gas and supply a fuel/gas mixture. The contactor-separator is coupled to receive the fuel/gas mixture and is configured to remove oxygen from the fuel and thereby generate and supply deoxygenated fuel with entrained purge gas and separated purge gas. The centrifuge-separator pump is coupled to receive the deoxygenated fuel with entrained purge gas and is configured to separate and remove the entrained purge gas from the deoxygenated fuel and supply the deoxygenated fuel and additional purge gas.

A deaeration device for a fluid includes a reservoir that contains a portion of the fluid, a fluid flow path that carries a portion of the fluid, a pressure regulating structure that creates a pressure gradient along the fluid flow path, a fluid exit in the fluid flow path, and a fluid entrance in the fluid flow path. The pressure gradient causes some of the fluid to exit the fluid flow path through the fluid exit and join the fluid in the reservoir. The pressure gradient causes some of the fluid from the reservoir to join the fluid flow path through the fluid entrance.

A method and system are disclosed for safe, efficient, economically productive, environmentally responsible, extraction and utilization of dissolved gases in deep waters of a rare type of “exploding” lake, where methane (CH.sub.4) is accompanied by abundant CO.sub.2. CH.sub.4 is combusted to generate electricity. CO.sub.2 usually is considered a contaminant requiring removal to avoid power loss. Cleaning high CO.sub.2 levels from CH.sub.4, however, is costly and causes CH.sub.4 loss. Venting CO.sub.2 is environmentally undesirable. Or, if CO.sub.2 is disposed in water flow returned to the deep lake, danger persists. CO.sub.2 and CH.sub.4 are degassed efficiently together and input into oxy-fuel combustion. Three process outputs are: degassed nutrients-rich water flow, power and CO.sub.2+H.sub.2O exhaust, all usable for industrially productive purposes. Extracting and using both gases together in an integrated method advances safety, economic productivity and environmental stewardship. Previously, it has not been possible to accomplish these ends together. The invention provides a hyper-efficient way.

Presently disclosed systems and methods for depositing a compound into a void in a sandwich panel or other structure are configured to reduce the air pressure in and around the void as the compound flows into the void, thereby reducing the amount of air trapped between the compound and the sandwich panel skin (under the compound, within the void) during the repair. Additionally or alternatively, presently disclosed systems and methods for deaerating a compound are configured to remove trapped air from the compound prior to use of the compound (e.g., prior to depositing the compound within a void for repairing the void). In some examples, the same system is configured to both deaerate the compound and deposit the deaerated compound to the void, all while in a reduced air pressure environment inside a vacuum chamber.

To provide a gas-liquid separator of a water electrolysis system, comprising: a liquid feeding atomizer and a gas-liquid separation chamber, wherein the liquid feeding atomizer includes a liquid feeding pressurized tube; and an atomizing spray head, in which the atomizing spray head converts a gas-liquid mixed liquor after pressurized by the liquid feeding pressurized tube into a mist droplet gas-liquid mixture. The gas-liquid separation chamber comprises a spiral flowing way, and the spiral flowing way extends the time that the mist droplet gas-liquid mixture spraying into the gas-liquid separation chamber flows downwards to the bottom of the gas-liquid separation chamber; an ultrasonic oscillation mechanism; a stirrer; an internal reservoir; and a filter mechanism, which performs the gas-liquid separation for unbroken bubbles in the mist droplet gas-liquid mixture through the pore difference.

A vacuum deaerator degasses material to be processed by placing a rotating rotor with a screen in a vacuum vessel, introducing a liquid material to be processed into the rotor from the interior thereof and causing the liquid to pass through the screen to refine the same. The vacuum deaerator is characterized in that: the screen is a cylinder with a circular cross-section and is in the form of a porous plate in which a plurality of through holes are opened in the radial direction of the cylindrical screen; and the screen is provided such that the area of inflow openings is greater than the area of outflow openings, where the inflow openings are openings of a plurality of penetration portions provided on the inner wall face of the screen and the outflow openings are openings of the plurality of penetration portions provided on the outer wall dace of the screen. Thus, the processing capacity of the vacuum deaerator is improved without increasing the size of the device.

Apparatus and methods for degassing and analyzing drilling fluid discharged from a wellbore at an oil and gas wellsite. The apparatus may be a drilling fluid analysis system having a gas analyzer, a fluid analyzer, and a degasser operable to release and separate mud gas entrained in the drilling fluid. The degasser may include a gas-liquid separator having a separator inlet configured to receive the drilling fluid containing the entrained mud gas, a first separator outlet for discharging the mud gas fluidly connected with the gas analyzer, and a second separator outlet for discharging degassed drilling fluid fluidly connected with the fluid analyzer.

The degassing apparatus removes liquid from a vacuum tank (1) with a suction pump (6) and supplies that liquid to a storage tank (9), sprays storage tank liquid into the vacuum tank through a convergent nozzle (7), removes gas from liquid in a state of reduced pressure inside the vacuum tank, and stores the degassed liquid in the storage tank. The storage tank is an airtight hermetically sealed tank provided with a reduced pressure retaining valve that discharges gas accumulated inside the storage tank.
