An oil-water emulsion breakup system. In one embodiment, the system includes an oil-water mixture inlet line configured to receive an oil and water liquid mixture, which may be stabilized by hydrophobic nanoparticles, surfactants of low HLB value, or both. A water injection inlet in communication with the oil-water mixture inlet is configured to direct water into the oil-water mixture inlet. A water sensor is in communication with the oil-water mixture inlet to sense percentage of water in the mixture. A water injection valve in the water injection inlet is in communication with the water sensor. A liquid-liquid separator has an inlet configured to receive a combination of the oil and water mixture and the water, with the separator separating liquid into an oil phase and a water phase. An upper leg in communication with the liquid-liquid separator receives oil separated from the separator. A lower leg in communication with the liquid-liquid separator receives water separated in the liquid-liquid separator.

Oil-water emulsion breakup (OWEB) process and system

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.

Annular axial mixing system for gas-liquid flow

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.

Gas&#x2014;liquid flow splitting (GLFS) system

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.

Flow conditioning system for homogenizing slug flow

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.
