Abstract: A combined degassing and flotation tank for separation of a water influent containing considerable amounts of oil and gas. A rotational flow is created in the tank which forces the lighter components such as oil and gas droplets towards an inner concentric cylindrical wall where they coalesce and rise to the surface of the liquid and are removed via the outlet. The heavier particles are forced down and sink to the lower part where they can be removed as a sludge. The water is discharged via an outlet in the lower part of the tank. The combined degassing and flotation tank is particular suited for use in oil production at sea for removal of oil and gases from water streams before the water is returned to the sea.

Abstract: An apparatus removes air or debris from a flow of liquid. The apparatus includes a shell having an inlet, an outlet, and an elongate inner cavity in fluid communication with each of the inlet and the outlet. A plurality of elongate coalescing medium assemblies are disposed within the cavity of the shell such that the coalescing medium assemblies are oriented substantially parallel to each other. Each coalescing medium assembly includes a plurality of wire mesh tubes oriented substantially parallel to each other. A wire mesh retaining wall substantially surrounds the tubes and holds the tubes together.

Abstract: A mobile separator system for oil and gas well production fluids consisting of a sled supporting a horizontal three phase separator vessel having an upright vessel or blowcase, with an upper section open to a lower section through a check valve, and a vertical two phase vessel mounted beside each other and seated within the horizontal vessel. A direct fired heater in the horizontal vessel provides the required heating for all three vessels. Production fluids tangentially enter the upper section of the upright vessel with gas rising and the fluid descending through a check valve to the lower section and then transferred into the horizontal vessel. The rising gas outlet is connected to the suction of a compressor and discharged under pressure to the intake of the vertical vessel. Separated gas from the horizontal vessel also is directed to the intake of the compressor. Oil and water separated in the horizontal vessel are transferred into storage or pipelines.

Abstract: Virgin stock is conducted to a paper or board machine and further to a centrifugal cleaner installation (12) into its first centrifugal cleaner step (12a1). From the first centrifugal cleaner step (12a1) the accept is conducted into a multi-layer headbox (10) to form a layer of the web determined according to the concerned fraction. From a second step (12a2) and/or from lower steps (12a3, 12a4 . . . ) of the centrifugal cleaner installation (12) a second fraction or more fractions are conducted into the multi-layer headbox (10) to form a second layer or other layers of the web, which are determined according to the pulp fractionation taking place in the concerned second step or lower steps.

Abstract: The device (6) includes a sealed casing (10) provided, in its lower part, with a bowl (22) for collection of a residual liquid, and an assembly (30) for purging the residual liquid which comprises means for evacuation of the liquid collected in the bowl and means for connecting the casing to the open air. The means for evacuation of the liquid include an orifice (36) formed in the wall of the casing substantially at the level of the bottom of the bowl (22). The means for connection to the open air include an orifice (34) formed in the wall of the casing (10) substantially opposite the orifice (36) for evacuation of the liquid.

Abstract: A two phase liquid media coalescer comprises a chamber such as a pipe (1) which may be fitted into a process system by way of pressure sealable fittings (23, 24). Contained within the chamber is a coalescer media (5) manufactured from fibers of polypropylene or other material. One end of the fibers may be secured to a media retaining plate (4). The fibers extend through the chamber in the direction of flow and are free at their other end. A two phase liquid enters the pipe and contacts the surface area of the fibers while passing through, thereby forming droplets of the minority phase of the liquid on the fibers.

A rotational flow is created in the tank which forces the lighter components such as oil and gas droplets towards an inner concentric cylindrical wall where they coalesce and rise to the surface of the liquid and are removed via the outlet (3) whereas the heavier parts are forced down where the heavy particles sink to the lower part where they may be removed as a sludge. The water is discharged via an outlet in the lower part of the tank. The combined degassing and flotation tank is particular suited for use in oil production at sea for removal of oil and gasses from water streams before the water is returned to the sea.

Abstract: A multi-phase separation system utilized to remove contaminants from fluids includes a pre-filtering module for filtering a contaminated fluid to provide a filtered contaminated fluid. A condenser module receives the filtered contaminated fluid and a contaminated gas phase for condensing the contaminated gas phase to a contaminated liquid. A phase reaction chamber converts the filtered contaminated fluid to a contaminated mist wherein the mist is subjected to a low energy, high vacuum environment for providing a first change of phase by separating into a contaminated gas phase and a liquid mist phase. The contaminated gas phase is carried out of the phase reaction chamber by a carrier air. A vacuum pump provides the low energy, high vacuum environment in the phase reaction chamber and delivers the contaminated gas phase to the condenser module for condensation providing a second change of phase.

Abstract: A system and a method for separating interdispersed gas and liquid components of an inlet stream includes introducing the inlet steam into a vessel having a dry gas outlet and a liquid outlet, passing the inlet stream into at least one vortex tube supported within the vessel, the vortex tube having a gas outlet and a liquid outlet, rapidly rotating the inlet stream within the vortex tube to separate entrained liquid and passing reduced moisture outlet gas from the vortex tube into the interior of the vessel and passing the outlet gas through a mist eliminator within the vessel to provide gas that is passed out the vessel dry gas outlet.

Abstract: Invention relates to methods for water removal from oil, oil products, gas condensate, and liquid hydrocarbons. The suggested invention aims at a more efficient water removal from the flows of hydrocarbons of different origin. Technical task of water removal is implemented via the selective filtration of hydrocarbons through a filtering element consisting of three tilted beds, wherein the first and the third beds are made of a porous-cellular metal or alloy with hydrophobic surface, while intermediate one is made of hydrophilic materials such as the porous-cellular metal or alloy with modified surface, celluloid foam or the cartridges filled with glass balls or glass fiber. The suggested method allows a high degree of water removal from the hydrocarbon medium under continuous regime without water phase settling. Apparatus for the implementation of this method is also described.

The coalescing and removal layers are shaped to receive and expel the air. Both layers can be supported by a frame and/or an outer support layer of polyester material.

Abstract: A Vertical Combined Production Facility, or gas-well production system, in which the separation of each phase (hydrocarbon gas, hydrocarbon liquids, and produced water), dehydration of natural gas, removal of minute traces of water from the hydrocarbon liquids, and polishing of produced water, are performed in a single pressure vessel. Additionally, the pressure vessel is installed in a vertical configuration such that the pressure vessel shell also serves as the structural support for a small deck and helideck. Additionally, the inlet heating of the well flow-stream is accomplished by a heat exchanger installed in the dehydration/regeneration heater (reboiler).
