Abstract: An annular axial mixing system for combined gas and liquid flow. The system includes a gas-liquid separator to separate a multiphase gas and liquid into a gas flow and a liquid flow. A lower leg in communication with the gas-liquid separator is configured to receive liquid flow. An upper leg in communication with the gas-liquid separator is configured to receive gas flow. An annular mixing chamber receives gas from the upper leg. A static liquid chamber, at least a portion of which is within the mixing chamber, is in communication with the lower leg and includes perforations therein to receive gas bubbles from the gas in the annular mixing section chamber in order to mix the flows.

Abstract: The present disclosure provides a gas-liquid flow separation system configured to separate a fluid stream containing both gas and liquid components into separate gas and liquid streams. The separation of the components permits the collection of data relating to the volume of each stream. In some embodiments, the separation system provides for the subsequent recombination of the streams in a homogeneous mixture for processing by downstream facilities. Also, the present disclosure provides a manifold system configured to receive fluid streams from a plurality of sources, combine the streams into a single blended stream containing both gas and liquid components. Subsequently, the system provides for separation of the gas from the liquid components and optional recombination of the same.

Abstract: Embodiments of a Flow Conditioning System (“FCS”) of this disclosure may be used for homogenizing a fluid containing a gas phase and a liquid phase. In some embodiments the FCS may be applied to a fluid containing hydrocarbons. The FCS may be located where appropriate, including but not limited to subsea. The FCS may be used for homogenizing slug flow. In embodiments, the FCS may be composed of an outer shroud pipe section, into which a concentric perforated smaller pipe is inserted at the top. The inlet slug flow regime is changed at the shroud section whereby the slugs are broken, transitioning to well-mixed flow regimes, such as bubbly flow or continuous churn flow. The bubbly or continuous churn flow that occur in the shroud section are forced to pass through the perforations of the perforated smaller diameter pipe, which promote a more thorough mixing of the phases upstream of devices such as multiphase pumps.

Abstract: Disclosed is a compact separation system suitable for separating components of a multiphase fluid stream. The compact separation system utilizes a cylindrical cyclone in conjunction with a filtration system. The filtration system incorporates filtration media having at least one of the following characteristics: hydrophilic-oleophobic characteristics or oleophilic-hydrophobic characteristics. The separation system is configured to substantially preclude gas under-carrying into the liquid conduit lines.

Abstract: A filter medium for oil-water separation, the filter medium being a composite, nanofibrous mat formed from electrospinning a single solution of one natural polymer and one synthetic polystyrene polymer together, where fibers of the natural polymer are reinforced by fibers of the synthetic polystyrene polymer. The nanofibrous mat may initially be hydrophobic and oleophilic, making it a suitable filter medium for separating oil from oil-water mixtures. The mat may be treated with one or more surfactants to change the surface wettability of the mat to hydrophilic and oleophobic for separating water from oil-water mixtures or to hydrophobic and oleophobic for separating oil and water droplets from wet gas.

Abstract: A wedge floatation device includes a bottom section and a sidewall positioned around a perimeter of the bottom section to contain a liquid within the wedge floatation device. The bottom section includes an outer portion and a plateau portion centrally positioned in the bottom section. The plateau portion is raised to a height above the outer portion and below a top edge of the sidewall. The plateau portion includes a groove that is substantially concentric with an outer perimeter of the plateau portion. The groove is designed to dampen the velocity of a liquid directed from the outer perimeter of the plateau portion to a center of the plateau portion. The bottom section further includes a transition portion extending between the outer portion and the plateau portion. The transition portion surrounds the outer perimeter of the plateau portion. The outer portion surrounds a perimeter of the transition portion.

Abstract: A method of determining solid particle surface energy includes placing solid particles in a container made of a very high surface energy material and pouring a liquid into the container. The method further includes tilting the container to drain out from the container a first subset of the solid particles floating at a top surface of the liquid and tilting the container to move the liquid away from a second subset of the solid particles that are below the top surface. The method also includes tilting the container to move the liquid back toward the second subset of the solid particles such that at least a portion of the second subset of particles floats at the top surface of the liquid and tilting the container to drain out from the container the portion of the second subset of the solid particles now floating at the top surface of the liquid.
