Abstract: In a bubble-column vapor mixture condenser, a fluid source supplies a carrier-gas stream including a condensable fluid in vapor phase. The condensable fluid in liquid form is contained as a bath in a chamber in each stage of the condenser, and the carrier gas is bubbled through the bath to condense the condensable fluid into the bath. Energy from condensation is recovered to a coolant in a conduit that passes through the liquid in the stages of the condenser. The bubble-column vapor mixture condenser can be used, e.g., in a humidification-dehumidification system for purifying a liquid, such as water.

Abstract: A number of pocketed apparatus for separating various materials are described. A pocketed cyclonic separator that includes a cyclone chamber, which includes interior chamber walls, an inlet connected to the cyclone chamber, and one or more pocket separators, located on the interior chamber walls, is described. A substance may be introduced through the inlet into the cyclone chamber so as to create a rotational force sufficient to generate a cyclone in the cyclone chamber. Forces generated by the cyclone will cause heavier material in the substance to move towards the interior chamber walls when in use. The one or more pocket separators define one or more pockets that trap heavier material in the substance when in use.

Abstract: Apparatus and method for degassing liquids particularly cationic monomers. Fluid comprising liquid to be degassed together with sweep gas is admitted tangentially into a column (10) and forced down the column by a tubular baffle (16) which defines, with the inner wall of the column, an annulus (18) that is closed at its top (20). After passing to the bottom of the annulus the fluid forms an even film over the inner surface of the column and gas disengaging from the liquid can rise up the column while liquid accumulates at the bottom of the column. To assist the disengagement of the gas from the liquid the column is preferably of increasing cross section towards the bottom so that the thickness of the film is also reduced.

Abstract: This is a high-efficiency item of equipment, for example for a well bottom for separating out gas from a liquid/gas mixture, based on the effects of flows of the cascade and segregated types. It consists basically of a sedimentation vessel whose lateral surface has holes in the upper portion, enclosing (i) a discharge pump, (ii) a suction pipe and (iii) the lower end of a production tubing. The vessel contains helicoidal surfaces for achieving segregated-type flow. A significant part of separation takes place above the level of the separator, in a medium in which there is a predominance of gas and the flow is in the form of a cascade.

Abstract: A gas separator connectable between the seating nipple/pump and the mud anchor of a well production line takes advantage of gravitational, shear and centrifugal forces to detrain gas from the formation fluid. An outer cylindrical tube is concentrically secured by upper and lower couplings in relation to an inner cylindrical tube having an axial flow passage and a plurality of radial perforations. The upper coupling is adapted for connection to the seating nipple/pump and the lower coupling is adapted for connection to the mud anchor. The couplings each have a passage therethrough to extend the inner tube axial flow passage in fluid communication between the pump and the mud anchor. The outer cylindrical tube has a plurality of inwardly downwardly centrifugally oriented passages for admitting liquid entrained with gas into an annulus between the tubes and for causing the admitted liquid to flow in a downward spiral in the annulus.

Inlet and outlet tubes are provided in the housing for directing refrigerant into and out of the accumulator. The inlet tube includes a first end fluidly connected to an inlet fitting at the upper end wall of the housing, and a second end located proximate the lower end wall of the housing. A longitudinal orifice is provided along the entire length of the inlet tube, from a location above the level of stored liquid refrigerant in the accumulator, to a location below the level of stored liquid. The orifice is oriented to direct fluid tangentially along the inside surface of the side wall. The inlet tube is formed by a strip of material where the side edges of the strip are brought together to define the opening, or the side edges can be brought into contact along a seam and a plurality of openings can be provided along the tube.

Abstract: The efficiency of progressing cavity pumps is drastically reduced if the liquid being pumped contains large volumes of gas. To alleviate this problem a gas separator is provided which can be attached to the suction of a downhole pump to remove gas from the liquid being pumped prior to the liquid entering the pump inlet. The separator has an elongate housing having an annular chamber with guides which direct the liquid gas mixture to flow in an annular path from the inlet to the outlet end. During this flow centrifugal forces act to displace the gas content to the central region from which it is removed via a separate central gas outlet so that liquid delivered to the pump inlet is greatly reduced in its gas content.

Abstract: A device for separating gas bubbles out of medical fluids, in particular blood, has a substantially cylindrical chamber, an inlet connection arranged in the longitudinal direction of the chamber, an outlet connection and a flow-guide member attached to the inlet connection and having a plurality of flow channels, which extend in a space curve out of the longitudinal direction of the chamber in a direction running substantially tangential to the inner wall of the chamber. An orifice, which is sealed by a hydrophobic membrane, is provided in the cover part of the chamber. Since the outlet orifices of the flow channels are arranged directly underneath the cover part, the membrane is circumflowed by the inflowing fluid, avoiding the formation of dead zones. The device makes it possible to separate out air bubbles with a substantial degree of reliability, without the danger of the hydrophobic membrane becoming obstructed from contact with the blood.

Abstract: The separator includes a vertical cylindrical pressure vessel having elliptical top and bottom heads. A mechanical device, referred to as a vortex tube cluster of vertical tubes, is mounted in the upper section of the vessel chamber, spaced above the bottom head to define a lower chamber section for fluid and solids separation. Pressurized drilling fluid returns are directed tangentially into the vortex tubes and a subsequent centrifugal action is generated. Contained gas separates and forms a gas vortex which exits upwardly from the vortex tubes and vessel top. The liquids and solids discharge into the vessel lower chamber section where solids settle by gravity to the bottom. The solids are withdrawn from the base of the vessel by a slurry pump. The oil and water components of the fluid layer also separate by gravity and are individually removed from the vessel.

Abstract: An apparatus for primary air/oil separation for an oil-flooded air compressor, the apparatus includes a tank having a sidewall, a bottom end and a top end. The sidewall and ends define a tank separation chamber. The apparatus further includes a flow conduit for flowing an air/oil mixture from the compressor into the tank separation chamber. A primary separator element is located in the chamber and provides primary separation of the air/oil mixture. The primary separator element is flow connected to the flow conduit and includes a body with at least two discharge ends and an arcuate elbow flow connected to each of the at least two discharge ends. Each elbow has an outer peripheral portion and an inner peripheral portion. As the air/oil mixture is forced through the separator element, the oil is drawn to the outer peripheral portion and the compressed air is located in the inner peripheral portion. In this way, primary separation of the oil and the air is achieved.

The separator includes three cast elements containing three formed chambers, a distribution chamber at the top of the device which supplies incoming liquid to a plurality of separators which operate on the vortex principle, a liquid collection chamber for collecting the essentially or substantially air/gas or bubble free liquid at the bottom of the device, and an air/gas bubble collection chamber above the vortex separators for collecting the gas/air or bubble containing liquid. These chambers are of cast construction and made of stainless steel so that no weld need be used. The device has essentially inline flow for the bulk of the liquid from inlet to outlet and clean streamline design with no dead spaces to prevent accumulations, build ups and problems associated with the same.
