A subsea separator vessels includes single machined blocks integrated into a hull so as to combine all the valves used in the process of separating the multiphase fluid in the interior of the blocks. The separator vessels have by-pass valves in their blocks, if necessary to interrupt the separation process. The blocks function as a structure for the separating vessels, thereby replacing all of the metal structure necessary to support the tubes and valves of a conventional manifold, thus reducing the total area occupied by the separation station in the seabed.

A system for treating liquids and solutions for separating components thereof, the system including a treatment vessel having a treatment chamber therein, a device for generating a gas-infused liquid under elevated pressure, and a device for stabilizing the gas-infused liquid such that most of the gas infused into the liquid by the device for generating a gas-infused liquid will remain in the liquid if pressure of the liquid is reduced to atmospheric pressure, and for flowing the stabilized gas-infused liquid into the treatment chamber so as to form a liquid layer including the stabilized, gas-infused liquid in the treatment chamber. The treatment vessel includes a discharge port through which some of the stabilized, gas-infused liquid in the liquid layer may be discharged from the treatment vessel, the withdrawn liquid is infused with an additional amount of the gas, again stabilized, and again flown the liquid into the treatment chamber.

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

A separation tank useful to separate a compressed gas from a byproduct of compression (such as a lubricant/coolant used in the compression process) can include one or more baffles. The baffles used in the separation tank can include a number of passages to permit a flow of compressed gas to pass. The passages can include a louver to assists in directing the flow and/or assist in further separation of the compressed gas from the lubricant/coolant. The louvers can appear on one side of the baffle, and in one form are located solely on the downstream side of the baffle. The baffle can include a relief for liquid leveling within the tank. Any number of approaches can be used to make the baffle, including cutting and/or stamping.

A coalescing filter element provides an integrated filter element with a three stage design with a hydrophobic or hydrophilic coalescing layer. A coalescing filter element comprises: a) At least one particulate filtration layer; b) A coalescing layer promoting coalescing of water particles, wherein the coalescing layer is downstream of the at least one particulate filtration layer relative to the flow of fluid through the element; c) An annular coalescing space downstream of the coalescing layer; d) A sump in a lower portion of the filter element in fluid communication with the annular coalescing space; and e) A hydrophobic layer downstream of the annular coalescing space, wherein fluid being cleaned by the element flows through the hydrophobic layer. The coalescing layer may be a hydrophobic or a hydrophilic coalescing layer. A filter assembly will include the coalescing filter element of the present invention.

A fluid treatment system combines cyclonic separators and gravitational separators for use in onshore and offshore oil and gas operations and elsewhere. The characteristics of apertures that interface between a gravitational separation chamber and a cyclonic separator are configurable in accordance with operational requirements. By selecting aperture characteristics, improved control and separation efficiencies can be achieved.

A fluid evaluation device for analyzing a fluid content within a container includes first and second fluid sampling conduits passing laterally into the container and respectively extending to first and second depths within fluid stored in the container, a common fluid conduit to which the first and second fluid sampling conduits extend for receiving fluid flowing out of the container through either of the first or second sampling conduits, and an optical device positioned along the common fluid conduit and including a viewing window for observing fluid flowing therethrough from the common fluid conduit.

A system for separating the components of an incoming oil-water mixture includes two electrode sets, one set arranged to apply an electrostatic field to an oil layer residing within a separator vessel and the other set arranged to apply an electrostatic field to the interface emulsion layer residing within the separator vessel. The first set of electrodes is in communication with a high voltage power source that ranges from 1 to 60 kV; the second set of electrodes is in communication with a low voltage power source that is no greater than 5 kV. Each set of electrodes may also be in communication with a second voltage source to provide increased power to promote effective coalescence. The system may also include power electronics to produce a variable amplitude and a variable frequency voltage supply to one or both electrode sets.

An oil/water separator for removing oil-containing constituents from an oil/water mixture includes a main filter designed to separate oil-containing constituents from the oil/water mixture. Untreated oil/water mixture is supplied to the main filter and is removed from the oil/water separator after passing through the main filter, wherein the oil/water separator is designed for supply and removal of these liquids in accordance with the hydrostatic principle. The oil/water separator has a control unit designed to temporarily charge the oil/water separator with control air, by means of which overpressure can be used to push oil/water mixture through the main filter.
