Abstract: An apparatus for separating natural gas from production streams comprising a liquid dispersion of water, sand, and natural gas is provided for. The separator comprises a vessel having an interior surface defining a spherical interior space. The interior space allows a production stream introduced therein to experience a velocity drop sufficient to allow separation of the natural gas from the sand and water components. The separator also comprises a stream inlet port in the vessel, a liquid drain in the lower end of the vessel, and a gas outlet port at the upper end of the vessel remote from the stream inlet port. A baffle is mounted in the interior of the vessel in the path of the production stream between the stream inlet port and the gas outlet port. The baffle is effective to spread and direct a high pressure production stream introduced into the interior space via the stream inlet port downward toward the liquid drain.

Abstract: A system and method for managing gas bubbles in a liquid flow system are described. In particular, according to the system and method, novel techniques reduce a volume of cavities in the liquid flow system and limit a cross-sectional area of the liquid flow system to a maximum cross-sectional area of tolerably sized bubbles. In this manner, by reducing the cavity volumes and limiting cross-sectional areas, the formation of intolerably sized bubbles and the aggregation of tolerably sized bubbles into intolerably sized bubbles are each substantially prevented. Also, bubbles may be removed from the system to reduce the quantity of bubbles that are to be managed.

Abstract: This disclosure relates to a method for deaerating a liquid layer such as a coating solution using electrostatic forces. A flow of charged particles is created above and moved towards a low conductivity liquid layer. The flow of charged particles causes localized thinning of the liquid layer which facilitates the removal of bubbles of entrained gas from the liquid by bringing those bubbles closer to the exposed surface of the liquid and rupturing them at that surface. This electrostatic deaeration technique is combined with other non-electrostatic liquid layer thinning techniques or degassing techniques to further facilitate removal of bubbles from the liquid in preparation of further processing of the liquid. The liquid layer may be stationary or flowing with respect to the application of charge particles.

Abstract: The invention relates to a device for separating gas and liquid from a medium flowing in a line, and to a method for separating such a medium, in particular a gas-liquid mixture, in the device, which separates gas and liquid particles from one another at high and low flow speeds. High-quality phase separation that is independent of the flow speed is achieved in that both a surface tension of the liquid and different forces of inertia of the liquid and gas prevent a flow of the liquid through openings of a separator element.

Abstract: An apparatus for carrying out a three-phase separation during treatment of wastewater and sludge, which includes a gas collector (1) which traps gases that rise in the settling basin during the treatment process. The gas collector has an inclined outer surface (2, 3) which ensures that sewage sludge can slide down unhindered. The angle of inclination (&agr;) can be adjusted in order to adapt the apparatus to different sewage sludges. The gas collector has a flexible tube (4) which is guided around a plurality of reversing or bending surfaces (5, 6, 7, 8) so that sections (10, 11) of the tube form the inclined outer surfaces (2, 3). Another section (15) of the tube defines the interior volume (V) of the gas collector. The resulting gas collector is simple to produce and effectively prevents the separation apparatus from becoming clogged by particles of sewage sludge adhering to the outer surfaces of the gas collector.

The blood filter (1) according to the present invention includes a housing (5) accommodating a blood inlet (8), a blood outlet (9), an air bubble outlet (14), and a filter element (3) disposed in the housing (5). The blood inlet (8) is preferably disposed in the vicinity of a bottom surface (7) of the housing. The housing (5) includes a spiral chamber (10) defined between an inner wall (5b) and an outer wall (5a) of the housing (5) and a center chamber (11) defined within the inner wall (5b). The spiral chamber (10) extends in a helix shape to surround the center chamber (11). Due to such a structure, even when air bubbles are introduced to the blood filter (1) through the blood inlet (8), the air bubbles are effectively separated from the blood in the spiral chamber (10). The blood filter having such a spiral chamber (10) is unlikely influenced by the blood flow rate and the amount of air bubbles.

Abstract: The system removes contaminating gases, such as radon, from water using a bubbling action. Contaminated water is sprayed together with air through a duct to a bottom region of a bubbling container. The water and air move generally in the same direction through the system, allowing the flow rate to be varied while maintaining forced air/water contact. The aerated contaminated water bubbles upwardly through the bubbling container and passes through one or more diffusing or mixing plates causing the aerated contaminated water to further break out contaminating gases into the air. At the top region of the bubbling container, the contaminating gases are vented while the decontaminated water flows into a tank. The decontaminated water can then be pumped to a desired location, for example, to a house water system.

Abstract: A liquid having certain undesired elements therein is distilled in a distillation column to form a vapor stream. This vapor stream is fed by means of an inert gas drive to a first container having an array of semi-permeable screens which are rotated at a speed of 3,000-10,000 rpm to generate vertical spiral vortexes which act on the vapor to separate out heavier impurities. An inert gas is employed to drive the vapor stream from the first container to the bottom of a second container having a narrower diameter array of semi-permeable screens, these screens being driven at a velocity of 6000-100,000 rpm. In the second container, the molecular species is separated from the main vapor stream by virtue of the exposure of the vapor to large centrifugal gravity forces generated by the horizontal velocity vectors of the rotating screens.

Abstract: There is disclosed a deaeration tank which can sufficiently deaerate object water, is decreased in size, and has high treatment capability. The deaeration tank includes a tank body which defines a deaeration chamber and receives object water, an air injection device disposed within the deaeration chamber for injecting air, a discharge passage for discharging object water from the deaeration chamber, and a bubble-scavenging member disposed in the discharge passage for scavenging fine bubbles contained in the object water which passes through the discharge passage.

During this ascent of coarse bubbles within the deaeration chamber, through contact with the object water, coarse bubbles attract fine bubbles contained in the object water, so that the object water is deaerated.
