Coalescer plates, coalescer plate units, and coalescers, are provided. An exemplary embodiment provides a coalescer plate for separating a mixture of immiscible fluids. The coalescer plate comprises a pattern of wetting and non-wetting regions, wherein the pattern is based, at least in part, on phyllotaxis.

A separation system for separating components of a flow of multi-phase fluid includes an elongate separator vessel oriented on an incline to define a lower inlet end having an inlet for receiving the fluid flow, a raised outlet end, and an inclined top inner surface extending from the inlet end to the outlet end. The system includes a lower weir plate positioned above the inlet end and an upper weir plate positioned below the outlet end having an upper edge defining a liquid level within the separator vessel, thereby allowing a lighter fluid component to flow over the upper edge into a upper section located forwardly of the upper weir plate. The system also includes a clear water pipe with a withdrawal opening positioned below the upper weir plate. The incline of the separator vessel is adjustable in accordance with the composition of the multi-phase fluid.

An apparatus for refining a liquid stream using 180 degree redirection and inclined plates. The apparatus includes a first flow chamber, a second flow chamber, and a separation chamber. The first flow chamber directs the liquid stream downwards in a first direction at a first velocity, the second flow chamber directs the liquid carrier upwards in a second direction opposite the first direction, and the separation chamber is disposed between the first flow chamber and the second flow chamber. The separation chamber includes a redirection portion that has inclined plates across which the liquid carrier flows and, as the liquid slows from a first velocity to a second velocity, the solid particles fall out of the liquid carrier and collect in the collection portion of the separation chamber.

Provided is an assembly including a vessel having first and second ends and an interior, an inlet diverter disposed in the interior at the first end, at least one flow baffle disposed in the interior and having a gas section including a plurality of gas openings extending through the baffle, a liquid section below the gas section including a plurality of liquid openings extending through the baffle, and a bottom surface spaced from a bottom interior surface of the vessel to define a fluid flow path between the bottom surface and the bottom interior surface, and at least one vane section disposed in the interior downstream of the at least one flow baffle, the at least one vane section having a bottom surface spaced from the bottom interior surface of the vessel to define a fluid flow path between the bottom surface and the bottom interior surface.

A system includes a vessel, a module, and an oil skimming trough. The vessel includes a feed inlet distributor. The feed inlet distributor includes an inlet pipe, a housing, and multiple vanes disposed within the housing. The inlet pipe is configured to receive a feed stream including oil and water. The housing defines multiple perforations. The vanes are configured to direct flow of the feed stream to exit the housing through the perforations. The module is disposed within the vessel downstream of the feed inlet distributor. The module includes multiple coalescer plates and a set of baffles disposed within the vessel downstream of the coalescer plates. The set of baffles includes a first underflow baffle, an overflow baffle, and a second underflow baffle. The second underflow baffle defines multiple perforations. The oil skimming trough spans longitudinally across the vessel.

Disclosed is an apparatus for the gravitational separation of the first and second liquid phases of a two phase liquid containing predominantly a continuous first liquid phase with a dispersed second liquid phase having a lower specific gravity than the first liquid. The apparatus comprises a tank defining an interior chamber. A feed inlet introduces the two 5 phase liquid into the lower portion of the chamber. The upper portion of the chamber has an upward flow zone through which the two phase liquid rises, with the dispersed second liquid rising more than the first liquid and being separated therefrom due to the second liquid's lower specific gravity. The second liquid forms a floating layer and a conduit directs separated second liquid from the floating layer to a second liquid outlet.

Disclosed herewith a separation device for performing phase separation on a three-phase liquid. The device includes: a housing; at least one pair of longitudinal baffle plates; a flow channel formed between every pair of longitudinal baffle plates; and collection chambers formed between adjacent pairs of longitudinal baffle plates. Each collection chamber is provided with a transverse baffle plate to separate the collection chamber into a first phase and a second phase collection cells. Each flow channel is provided with multiple lateral baffle plates to separate the flow channel into multiple sub-channels. In the areas of each longitudinal baffle plate where the first phase and second phase collection cells are located respectively, said longitudinal baffle plate is provided with a first and a second phase guiding holes in communication with the first phase and the second collection cells respectively.

A scum or floating oil concentration device comprises a scum or floating oil concentration cone (11) and a scum or floating oil conveyor (12). Said scum or floating oil conveyor (12) is arranged above said scum or floating oil concentration cone (11). Said scum or floating oil conveyor (12) comprises a conveying helix (1) rotating around a shaft, a scum or floating oil conveying pipe (2) and a skimmer (3). Said conveying helix (1) is arranged inside said scum or floating oil conveying pipe (2). An opening is arranged on said scum or floating oil conveying pipe (2). Said skimmer (3) is arranged at said opening of said scum or floating oil conveying pipe (2). An inclined separation plate (13) and a scum or floating oil collection and concentration system are further provided in the present invention.

A mechanical separator for separating a fluid sample into first and second phases within a collection container is disclosed. The mechanical separator may have a separator body having a through-hole defined therein, with the through-hole adapted for allowing fluid to pass therethrough. The separator body includes a float, having a first density, and a ballast, having a second density greater than the first density. A portion of the float is connected to a portion of the ballast. Optionally, the float may include a first extended tab adjacent a first opening of the through-hole and a second extended tab adjacent the second opening of the through-hole. In certain configurations, the separator body also includes an extended tab band disposed about an outer surface of the float. The separator body may also include an engagement band circumferentially disposed about at least a portion of the separator body.
