A stirrer is provided such that a fluid being processed can be more efficiently shown by way of the action of an intermittent jet flow and processing capacity can be improved. The stirrer concentrically includes a rotor that includes a plurality of flat vanes and that rotates, and a screen that is place around the rotor. The screen includes a plurality of slits in the circumferential direction thereof, and screen members that are positioned between adjacent slits. The fluid being processed is discharged by rotation of the rotor from the inside of the screen to the outside as an intermittent jet flow through the slits. The width of the distal working face on the distal end of the vane in the rotational direction is smaller than the width of the basal end of the vane in the rotational direction.

A device for separating immiscible fluids of different densities from a liquid-containing emulsion, includes a longitudinal rotary drum having a longitudinal axis of rotation. The drum includes, longitudinally from upstream to downstream and between at least one upstream inlet and downstream outlets: a solid body rotation stage having an inlet and including at least one longitudinal inner partition for causing circumferential solid body rotation; a migration and coalescence stage including at least one longitudinal partition for causing circumferential solid body rotation, the partition delimiting at least one longitudinal channel communicating with the solid body rotation stage; and an extraction stage including at least one liquid outlet that has an overflow edge and extends along a longitudinal flow space communicating with the migration and coalescence stage via at least one longitudinal passage, and including a downstream liquid discharge space communicating with the outlet and connected to a downstream discharge port.

The invention relates to a device for treating fluid mixtures, which contain gases, such as in particular hydrogen (H2), air, nitrogen (N2), or natural gases, and liquids, such as in particular ionic liquids, hydraulic fluid, or process liquids, comprising at least a first separation stage (29) for separating the fluid mixture into a liquid fraction and a gas fraction, which is contaminated with a remaining liquid fraction, from which gas fraction said remaining liquid fraction is removed in at least one further separation stage (67).

This liquid/gas separator for centrifugal motor compressor includes a sump internally equipped with at least one gas separator stage suitable to separate a gaseous phase from a liquid phase accepted in the sump entry. The sump internally includes a compartment in which the gaseous phase is separated by a separator stage, and in which is assembled by a compressor stage of the motor compressor.

The invention relates generally to a de-aeration apparatus and system, and more particularly, to an apparatus and system suitable for de-aerating highly viscous fluids comprising a vacuum chamber, an annular disk for rotating within the chamber, and a fixed baffle covering a portion of the surface of the annular disk and thereby defining a predetermined path by which the fluid to be de-aerated is spread more quickly into a thinner layer on the disk, exposing a greater amount of air/gas bubbles from the fluid in a shorter amount of time and resulting in a higher quality product than conventional de-aeration systems allow.

Systems and methods for extracting hydrocarbon gas utilize a vacuum chamber with a mud chamber portion that is expandable and contractible. Gas is extracted at vacuum pressures.

A process of producing degassed liquid sulfur using process gas containing H.sub.2S to agitate the liquid sulfur being degassed while in contact with a degassing catalyst. Process gas is less costly and less complicated and quickly accomplishes substantial degassing rendering the liquid sulfur much safer in storage and transportation.

Systems for removing gas from a sealant and transferring gas-less sealant to an applicator are provided. The system may comprise: a rotatable chamber including: a first opening for receiving sealant; a hollow conduit arranged such that when gas accumulates in the center of the rotatable chamber when the rotatable chamber is rotating, the gas is ventable from the rotatable chamber; a second opening for receiving gas-less sealant from the rotatable chamber after the gas is vented from the hollow conduit; and a motor operatively configured to rotate the rotatable chamber; and a gas-less sealant applicator in fluid communication with the second opening of the rotatable chamber such that gas-less sealant released by the second opening is flowable into the applicator. The system may also include a robot arm including an end effector with a sealant dispensing nozzle. A method for applying sealant to an aircraft structure is also provided.

In an agitator in which cavitation arising during treatment of a fluid being treated is suppressed, a stator part S is provided with a plurality of penetration parts in the circumferential direction of the stator part S, and a stator main part positioned between adjacent penetration parts. When a fluid is discharged from the inside of the stator part S to the outside through the penetration part by the rotation of a rotor, in the stator part S for the agitator treating the fluid, the side facing a blade of the rotor is an inner wall surface, the side facing a blade of the rotor is an inner wall surface, the side facing the side opposite to the blade of the rotor is an outer wall surface, an opening of the plurality of penetration parts that is provided in the inner wall surface is an inflow opening, and an opening of the plurality of penetration parts that is provided in the outer wall surface is an outflow opening, the opening area of the inflow opening being larger than the opening are of the outflow opening.

The de-aerator can be used to separate air from oil in an aircraft engine lubrication system. The de-aerator can include a swirler cavity extending circumferentially around axis and axially between a proximal wall and a distal wall, a separation path dividing within the swirler cavity into a radially outer oil segment leading to an oil outlet and a radially inner air segment leading to an air outlet, and a swirling conduit portion having a length turning around the axis upstream of an opening in the proximal wall along the separation path.
