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: The separator (1) has a tubular inlet opening (2) and two tubular outlet openings (3, 4) which are connected with one another in a flow-carrying manner. A separating device (6) is disposed in the flow direction (5) between the inlet opening (2) and the outlet openings (3, 4). One of the outlet openings (3) carries substantially only separated liquid and the other outlet opening (4) carries substantially only gas freed of liquid. An outer tube (7) surrounds an inner tube (8) with an all-around space between them. The inner tube (8) is connected at one end to the inlet opening (2) in a flow-carrying manner, and at the other end is associated with the outlet opening (3) for the separated liquid.

Abstract: An inertial gas-liquid separator includes a housing having an inlet for receiving a gas-liquid stream, and an outlet for discharging a gas stream. Nozzle structure in the housing has a plurality of nozzles receiving the gas-liquid stream from the inlet and accelerating the gas-liquid stream through the nozzles. An inertial collector in the housing in the path of the accelerated gas-liquid stream causes a sharp directional change thereof and in preferred form has a rough porous collection surface causing liquid particle separation from the gas-liquid stream of smaller size liquid particles than a smooth non-porous impactor impingement surface and without the sharp cut-off size of the latter, to improve over all separation efficiency including for smaller liquid particles. Various housing configurations and geometries are provided.

Abstract: An aircraft separator system for removing moisture suspended in a gas of an aircraft waste system includes a waste tank and a vacuum source operatively coupled to the waste tank for creating a vacuum for drawing the waste material into the tank and drawing the gas with the moisture suspended therein out of the tank. A disposable separator housing for removing moisture suspended in the gas is disposed on the tank and removably coupled between the waste tank and the vacuum source such that the entire separator housing may be detached from the waste tank and vacuum source and discarded. A two-stage filter is contained within an interior of the housing without extending into the waste tank. The filter has at least two areas of different density mesh defining two stages including a first area located proximal to a separator inlet opening which is less dense, and a second area located proximal to a separator outlet opening which is more dense.

Abstract: The steam/water separator includes a lower standpipe for receiving a two-phase mixture of water and steam at its lower end. Internal threads or elements spaced about the interior wall of the standpipe impart a swirl to the incoming mixture, producing a thin film along the walls. Standard pick-off rings or a porous wall may be employed to separate the liquid from the vapor. A central swirl is imparted to the flow in the region dominated by vapor. This combination of peripheral swirl followed by a central swirl for steam/water separation affords minimum pressure losses along the separator with reduced sensitivity to inlet and submergence conditions.

Therefore, a aerosol generator can function as a device characterized with the alternative distributions of a narrowly size-distributed aerosol with high concentration in mass, and the liquid or solid aerosol can be generated thereof. The Geometric Standard Deviation (GSD) of the droplet size distribution can be kept under 1.

Abstract: A high capacity marine separator (30) is disclosed which uses a first stage formed by an inertial vane separator (32), a second stage formed by a coalescer stage (36) and a third stage formed by an inertial vane separator (34). The coalescer stage (36) is canted from vertical relative to the air flow direction which increases the surface area for air flow, increases the drainage rate of water from the coalescer section and provides an improved air flow distribution to the second inertial vane separator with higher velocities near the top of the second inertial vane separator. The inertial vane separators (32, 34) have flush cavities to reduce obstruction to air flow and have vanes that are greater than three inches in wavelength and spaced greater than one inch apart. The marine separator is capable of flow velocities of 50 standard feet per second.

Abstract: A method of removing particulates from a gas stream involves introducing the gas stream in a turbulent flow condition into and through a flow passage situated over spaced surfaces defining a plurality of stagnant, turbulent-free regions of gas in which there is no net gas flow and which communicate with said gas stream and arranging the stagnant regions near the flow passage so that turbulent eddies of said gas stream carrying suspended particulates penetrate spaces between the surfaces and then decay in said stagnant regions defined therebetween where said particulates are trapped and deposited mechanically on said surfaces within each of said regions. The deposits accumulate at bottoms of the regions and can be periodically removed.

Abstract: In a device for separating oil from the blow-by exhaust vapors of a combustion engine, a filter stack is mounted in a canister having an inlet port for the intake of vapors from the engine, a gas outlet port for connection to a source of suction for causing the vapors to flow through the canister, and a discharge port communicating with a flow passage for removal of condensed oil. The filter stack is operatively arranged so that the vapors pass in contact with and through the filter stack. A plate partially surrounds the filter so that the oil in the vapors condense, and flow outwardly through the passage between the plate and the interior wall surface of the canister.

Abstract: A melt is converted into pieces by being converted to individual quantities that are dropped onto a cooling surface. Disposed above the cooling surface is a hood having a suction outlet for conducting waste air to a cleaner. Disposed in the hood upstream of the suction outlet is an arrangement of surfaces defining a serpentine flow path for the waste air so that a vaporous component of the waste air crystallizes on the surfaces. The surfaces are formed by plates mounted on a common transport carrier which periodically moves the plates against a scraper for scraping off the crystallized material. Alternately, the surfaces can be defined by endless belts which move against scrapers.

The valve remains closed until there is sufficient condensate in the reservoir to push it open. After a predetermined amount of condensate drains out, the check valve closes.

Abstract: A venting mechanism which includes three members. A first member having threads defined thereon connected to a second offering a hexagonally shaped external surface. The third member features a bore which defines an annular surface at the intersection with a bore through the second member. A baffle is located within the bore of the second member by engagement with the annular surface defined between the second and third member. A Gortex film and a wire mesh placed within the bore of the third member are retained by a rolled lip thereof. In this manner, the baffle and the Gortex film act to maintain liquid on one side of the breather while allowing gases to freely pass therethrough.

Abstract: In accordance with the method of this invention, sulfur is removed from the gas stream exiting a sulfur storage tank through condensation and impingement of droplets and/or particles of elemental sulfur on the baffles and wall(s) of indirectly cooled scrubber-condenser. In order to effect the melting and return to the liquid sulfur storage tank of any sulfur collected on the baffles and wall(s) of the scrubber-condenser, said baffles and wall(s) are periodically heated, preferably with indirect steam. The scrubber-condenser apparatus of this invention is designed to effect the condensation and solidification of sulfur from the gas stream and to maximize the impingement of sulfur droplets and particles upon its baffles and internal wall(s) by repeatedly changing the flow direction of said gas stream. The scrubber-condenser is vertically mounted on a liquid sulfur storage tank and is connected directly to a vent located on top of the tank.

Abstract: Slug flow is substantially prevented in cylindrical pipes and other conduits by placing a generally flat plate partition extending within the pipe and dividing the pipe into a gas flow space and a liquid flow space. The position of the partition and the cross-sectional flow areas of the gas flow space and the liquid flow space are determined by predetermining that the pressure losses of gas flow and liquid flow should be substantially equal.

Abstract: A liquid-vapor separator for two-phase fluids in general and specifically a steam-water separator in a steam drum of a steam generator includes axial or radial spinner blades to create a centrifugal motion which causes liquid to be forced outward against the outer wall and the vapor to be concentrated in the center. Conical extraction skimmers systematically extract and discharge the liquid outwardly and downwardly through the side walls such that it impinges on an oval discharge screen surrounding the skimmers. The vapor flows out the top through a central opening and enters a secondary separator packed with crimped wire mesh encased in a perforated enclosure.
