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.

The present invention provides a dehydrogenation tank. An atomization spray is disposed at the center of the upper part of the dehydrogenation tank, and flow stirring modules used for stirring a flowing solution are respectively disposed at the middle and the bottom of the dehydrogenation tank. Each of the two flow stirring modules includes at least two layers of flow stirring meshes. By means of disposing the atomizing spray and the flow stirring modules in the dehydrogenation tank, the TRO solution flowing into the dehydrogenation tank are fully stirred, so that hydrogen gas mixed with the TRO solution is able to diffuse out fully and rapidly, thereby increasing dehydrogenation efficiency as well as reducing volume of the dehydrogenation tank. In addition, the present invention also provides a ballast water treatment system having the dehydrogenation tank.

A particle diameter is decreased and a surface area per unit flow amount is increased by spraying a VOC-containing liquid from a spraying device spraying that is a two-fluid nozzle in a vacuum container, so that only water in the VOC-containing liquid can be greatly evaporated and exhausted, and a concentrated VOC-containing liquid having high concentration can be refined and processed.

A deaerator includes a tank, a spray unit, a steam supply unit, a bleed unit and a discharge pipe. The spray unit is disposed at an upper portion of the tank and configured to supply water to the tank. The steam supply unit is disposed inside the tank to supply steam to the tank. The bleed unit is disposed at the upper portion of the tank and adjacent to the spray unit. The bleed unit is configured to bleed air from an inside of the tank. The discharge pipe is configured to discharge water without air to an outside of the tank.

Oil-gas separators and methods of using the oil-gas separators are disclosed. An exemplary oil-gas separator comprises a first fluid channel for receiving a well fluid, the first fluid channel having an open proximal end, a sealed distal end, and a plurality of perforations in a distal portion of the first fluid channel's exterior wall for expelling well fluid comprising oil and entrained gas into an annular space between the oil-gas separator and a well casing to produce gas-reduced oil and a second fluid channel for receiving the gas-reduced oil, the second fluid channel having a sealed proximal end, an open distal end for expelling the gas-reduced oil to the Earth's surface, and a plurality of perforations in a proximal portion of the second fluid channel's exterior wall for receiving fluid from the annular space.

Systems and processes for treating, reducing and/or disposing of leachate created by a landfill system by aerating, spraying and/or stripping leachate in a controlled environment to promote evaporation of a water component of the leachate, to strip a portion of ammonia from the leachate and/or to promote biological decomposition of the leachate. The reduced or concentrated leachate produced by the system or process, whether liquid, solid or slurry, can be disposed of as allowed or desired at a cost benefitted by the reduced volume and/or treated condition of the leachate.

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.

The described air-oil separation apparatus for an oil system of a gas turbine engine includes an oil tank having an oil impingement surface disposed on a tank bottom proximate an oil tank outlet and a centrifugal air-oil separator mounted within the oil tank. The centrifugal air-oil separator has an oil outlet that feeds an impingement nozzle having an outlet oriented, in operation, to eject an oil jet from the centrifugal air-oil separator to impinge the oil impingement surface at an intersection point spaced apart from the oil tank outlet.

A three-stage tubular T-shaped degassing device with microbubble axial flow and spiral flow fields is provided, which is applied to quick degassing of a gas-liquid two-phase flow. The three-stage tubular T-shaped degassing device adopts a quick degassing technology combining a microbubble uniform mixed rotational axial flow field and a spiral runner conical spiral flow field with layered jet collision reversing depth degassing. A microbubble uniform mixer is configured to adjust gas-liquid two-phase flow containing big bubbles into microbubble uniform mixed axial flow. A microbubble cyclone is configured to adjust the microbubble uniform mixed axial flow into multiple strands of rotational axial flows containing microbubbles. A rotational axial flow degasser implements the horizontal type microbubble uniform mixed multiple strands rotational axial flow degassing operation to remove most microbubbles to form axial flow gas and axial flow liquid.

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.
