A contactor/separator is formed from a vessel; an inlet for receiving a vapor/liquid mixture; an inlet for receiving a superheated vapor; a hub located within the vessel, the hub including a plurality of vanes for imparting a centrifugal motion to the vapor/liquid mixture or the superheated vapor; an outlet in a bottom of the vessel for removing liquid; and an outlet for removing vapor from the vessel. A method is also provided for heating and separating liquid and vapor from a hydrocarbon feedstock comprising introducing a hydrocarbon feedstock into a contactor/separator: introducing a superheated vapor into the contactor/separator such that it contacts and vaporizes a portion of the feedstock within the contactor/separator; separating unvaporized feedstock from vaporized feedstock in the contactor/separator; removing the vaporized feedstock and the superheated vapor through a first outlet; and removing the unvaporized feedstock through a second outlet.

A gas-liquid separation apparatus includes a crust and a separating pipe located in the crust. The crust includes an annular wall and two lids covering two ends of the wall. The crust has a cavity surrounded by the wall and the two lids. An inlet extends through one lid and an outlet extends through the other lid. The separating pipe is disposed in the cavity of the crust and in communication with the inlet and the outlet of the crust. A plurality of apertures is defined in a body of the separating pipe and in communication with a space inside the separating pipe and the cavity of the crust. The liquid with gas dissolved therein enters into the separating pipe via the inlet of the crust. The liquid is degassed by the separating pipe. The de-gassed liquid exits the separating pipe via the outlet of the crust.

A variety of improved hydroclone based fluid filtering systems are described. The hydroclones generally include a tank having an internal chamber and a filter (preferably a surface filter) that is positioned within the internal chamber. The filter defines a filtered fluid chamber within the internal chamber of the tank. The hydroclone may be operated such that a vortex of flowing fluid is formed between the chamber wall and the filter with the filter being located in the center of the vortex. With this arrangement, the filter acts as a cross-flow filter. In one aspect of the invention, the filter is a stepped filter. In another aspect of the invention, the filter is an surface filter, as for example, an electroformed metal surface filter. In some preferred embodiments, the openings in the filter are arranged as slots that extend substantially vertically so that they are oriented substantially perpendicular to the flow path of fluid flowing in the adjacent portion of the vortex. In another aspect of the invention, a circulating cleaning assembly is provided in the hydroclone region. The cleaning assembly is arranged to help clean the filter and is driven by the vortex of flowing fluid formed in the hydroclone region of the internal chamber. In yet another aspect of the invention, improved hydroclone intake structures are described. The described hydroclones may be used to filter water and other fluids in a wide variety of applications.

The present invention relates to a device for treating a gas/liquid mixture, comprising: an inlet opening for the mixture; an outlet for the mixture located downstream; rotating means arranged in the tube for setting the mixture into rotating movement; one or more outlet openings arranged downstream relative to the rotating means for allowing a part of the mixture to flow laterally out of the tube; a return conduit arranged in axial direction through the rotating means for reintroducing into the tube the flow which has exited via the outlet openings; and divergence means arranged close to the outlet opening of the return conduit for allowing the reintroduced flow to diverge laterally.

The invention relates to a water separator for air-conditioning systems, preferably for aircraft air-conditioning systems, comprising a swirl generator, a housing surrounding it, a separation chamber arranged around the housing for the collection of the water separated at the inner wall of the housing, which opens in a separation sump, and at least one opening provided toward the separation chamber in the housing. In accordance with the invention, the separation chamber is made in multistage form, with the first stage of the separation chamber serving the accumulation of the water drops, the second stage of the separation chamber serving the deposition of the accumulated water drops and the third stage of the separation chamber serving the extraction of the air mass flow.

A cyclonic fluid separator for separating condensable, liquid and/or solid components from a fluid mixture includes an upstream fluid inlet section in which the fluid mixture is accelerated to a supersonic velocity to expand and cool the fluid mixture such that one or more condensable fluid components are liquefied and/or solidified; a downstream separation section in which condensables depleted and condensables enriched fluid fractions are separated and fed into separate outlets; and a midstream vortex generation section which includes a plurality of tilted wings of which the wing tips are located at relatively large mutual spacings and at a small spacing from the inner wall of the midstream vortex generation section such that during normal operation of the separator adjacent to the various wing tips widely spaced vortices of swirling fluid are generated in the fluid stream flowing through the housing, which vortices are still separated from each other at the entrance of the downstream separation section.

Axial flow demisting cyclone for separation of a mixture of gas and liquid including an inlet 30 for gas containing liquid droplets and an outlet 31 for substantially dry gas, including a mainly cylindrical cyclone tube 16 with at least one path of slots or perforations 19 allowing a part of the fluid, including separated liquid, to flow out of the cyclone tube 16. The demisting cyclone also includes a swirl inducing device 17, 18 to set the entering fluid in rotation. This swirl-inducing device is formed from a cascade of vanes 18 attached to a concentric core body 17, preferably cylindrical in shape, which extends towards the wall of the cyclone tube 16, the vanes 18 being in the longitudinal direction of the vanes from their leading edge 23 to their trailing edge 24.

A device for the separation of solid objects (9) from fluid flowing in a conduit tube (2) includes a housing that includes a tubular outer wall (3) and a tubular inner wall (4). Between these is delimited a collecting space (8). Concentrically relative to the inner wall (4) is provided a rotation-symmetrical central body (12) which at opposing ends cooperates with flow converting devices (15, 16), which transform incoming flow to a rotative motion and outgoing flow to an axial motion. In the inner wall (4) are recessed tangentially separated holes (20) of elongated shape, through which the scrap objects may pass and be collected in a collecting space (8). In the collecting space (8) a calm flow operation is obtained which guarantees that collected scrap objects are not carried away and returned to the main fluid flow through the separation device.
摘要:
A centrifugal vapor/liquid separator separates the vapor and liquid in a flash of hydrocarbon and steam mixture, such that only the vapor stream is fed and processed further downstream. The design of the separator ensures that all partially wetted surfaces in the separator, except at the vapor outlet pipe, are well-wetted and washed by the non-vaporized liquid portion of the feed or by injection of external liquid thus ensuring that no coke deposition occurs inside the separator. The flash temperature in the separator therefore can be increased beyond the typical limit thus achieving a deeper cut into the feed and recovering a larger fraction of the feed as vapor for further downstream processing.
