A passive phase separator includes an inlet to receive two-phase flow into an inner conduit and an outer conduit. An annulus is formed between the inner conduit and the outer conduit. A hydrophobic screen separation device prohibits a flow of liquid from the two-phase flow into the annulus while allowing a flow of gas from the two-phase flow into the annulus, and a gas flow outlet releases the flow of gas from the annulus.

The present invention is in the field of a system for gas recovery from wastewater, a method for treating wastewater, and a method wherein ammonia and carbon dioxide are recovered. Typically a wastewater stream is fed into the system, treated and stripped from ammonia and carbon dioxide, and a cleaner stream is released.

This invention is an air block for industrial, medical, and non-medical uses. For example, the air block is connected to the proximal end of a vascular access catheter. The air block is either removably connected to the proximal end of the catheter or it is integral to the proximal end of the catheter. The air block permits introduction of other catheters or instrumentation through its central lumen and on into a lumen of the catheter while minimizing fluid loss or gain into the catheter. The air block further prevents air from entering the catheter and provides for removal of the air or other gas from the central lumen before it can enter the catheter where it could cause harm to the patient. The air block can be attached to various standard proximal catheter terminations including Luer fittings and hemostasis valve outer barrels.

A device which includes a pulse dampener and a degasser or de-bubbler. The device includes a fluid flow path and a fluid chamber located within the device. In addition, the device includes a pulse dampening membrane for dampening pulses in the fluid as it flows through the device. The device also includes a degassing membrane for degassing the fluid as it flows through the device, and/or a de-bubbling membrane for removing gas bubbles from the fluid as it flows through the device. The degassing or de-bubbling membrane can be separate and distinct from the dampening membrane. The de-bubbling membrane can be in addition to or in place of the degassing membrane in some embodiments.

A hydronic system separator has an air separator with a vent release mechanism to remove air from the fluid within a hydronic system. The separator includes a magnetic assembly for collecting ferrous particles from the fluid. One or more screens are used to remove other particles from the fluid. The separator housing includes a removable debris collection receptacle that has a drain assembly.

A device for the treatment of fluid mixtures containing gases, such as in particular hydrogen, air, nitrogen or noble gases, and liquids, such as in particular ionic liquids, hydraulic oil or process liquids, having at least one separating stage (30) for separating the fluid mixture into a gas portion and a liquid portion, which, routed into a collection space (32), results in a float (44) rising, which, at a predeterminable liquid level in the collection space (32), actuates, without contact, a sensor device (42), which preferably actuates a discharge device for the purpose of draining the collection space (32), resulting in the lowering of the float (44), is characterized in that the outer circumference of the float (44) is guided axially displaceably along the inside of the housing wall (54) of the collection space (32), and in that the float (44) has at least one point of passage (50) for gas and/or liquid, which interconnects parts of the collection space (32) in a media-conveying manner, which parts are spatially separated from one another by the float (44).

A gas and liquid separation system could be said to have a passage with an inlet connected to receive a mixed gas and liquid flow. An air separation tube extends into the passage at a location downstream of where the inlet is connected with an upstream tube end upstream in the passage relative to a downstream tube end. The upstream tube end provides an obstruction to the mixed gas and liquid flow, to cause separation of the gas from the mixed gas and liquid flow. A liquid tube is connected to the passage at a location downstream of the air separation tube.

An air bleeder includes a branch, a lubricant supply conduit, and a return conduit. Lubricant stored in a tank is to be supplied to a valve provided in a machine tool via the lubricant supply conduit. The lubricant supply conduit includes a first supply conduit, and a second supply conduit. The first supply conduit connects the branch and the tank. The second supply conduit connects the branch at a first connecting position and the valve. The return conduit connects the tank and the branch at a second connecting position higher than the first connecting position in a height direction along a height of the air bleeder to return lubricant to the tank and to remove air from lubricant in the lubricant supply conduit.

A dispersing device includes: a casing having a liquid inlet; a rotating body accommodated in the casing and pivotably attached to a rotating shaft from one end of the rotating body; a liquid channel having, on the other end of the rotating body, a passage through which the liquid from the liquid inlet passes, and, inside the rotating body, a segment extended radially around the rotating shaft toward an outer side perpendicular to the rotating shaft and from the other end of the rotating body toward the one end of the rotating body in a direction of the rotating shaft axis and in which a cross section shape perpendicular to the rotating shaft is annular; and one connecting hole in the rotating body connecting the liquid channel with the exterior of the rotating body downstream of the liquid channel.

Systems and methods are described for supplying a rinsing liquid including ultrapure water and an ammonia gas. The system includes an ultrapure water source and a gas mixture source in fluid communication with a contactor. The gas mixture includes ammonia gas and a carrier gas. The system includes a control unit configured to adjust a flow rate of the ultrapure water source such that an operational pressure of the contactor remains below a pressure threshold. The system includes a compressor configured to remove a residual transfer gas out of the contactor. The contactor generates a rinsing liquid having ultrapure water and a concentration of the ammonia gas dissolved therein. The system includes a pump in fluid communication between the contactor and an outlet. The pump is configured to deliver the rinsing liquid having a gaseous partial pressure below the pressure threshold at the outlet.
