Systems and methods for separation of hydrocarbon containing fluids are provided. More particularly, the disclosure is relevant to separating fluids having a gas phase, a hydrocarbon liquid phase, and an aqueous liquid phase using indirect heating. In general, the system uses a first three-phase gas separation. The gas stream separated out is cooled with the resulting hydrocarbon condensates reintroduced to the stream of hydrocarbon-liquid phase that was separated from the fluid. The resulting combined stream can be cooled or heated as necessary.

A system for collecting solid particles accumulating at the bottom of a subsea oil/water separation station of an installation for the subsea disposal of water produced during the deepwater subsea production of hydrocarbons, comprises at least one vertical drainage channel intended to open into a lower part of a horizontal body (of the oil/water separation station, a discharge pipe to be positioned horizontally under the horizontal body of the oil/water separation station and into which the drainage channel opens, and a high-pressure slurry ejector having a suction port connected to the discharge pipe via a supply valve.

MIU and metals are removed from Tallow or Seed based oils (feedstock) utilizing water treated by reverse osmosis and specific operating conditions using a very high RCF centrifuge. A relatively small quantity of the RO water (3% to 20% by weight) is added to the feedstock to attract the MIU and metals. The mixture is then centrifuged at an RCF in excess of approximately 6500. Temperature, flow rate to control Residence time and backpressure in the centrifuge are selected. The process separates the RO water with the MIU and metals from the feedstock.

A system for separating a multiphase well stream into a solids fraction, a water fraction, an oil fraction and a gas fraction includes a transportable support surface; a solids separator which is mounted on the support surface and is configured to receive the multiphase well stream and separate the well stream into a first heavy fraction primarily comprising the solids fraction and a first light fraction primarily comprising the gas, oil and water fractions; and a multiphase fluid separator which is mounted on the support surface and includes a first separator section and a second separator section which is positioned vertically below and connected directly to the first separator section. The first separator section is configured to receive the first light fraction and separate the first light fraction into a second light fraction primarily comprising the gas fraction and a second heavy fraction primarily comprising the oil and water fractions. The second separator section is configured to receive the second heavy fraction and separate the second heavy fraction into a third light fraction primarily comprising the oil fraction and a third heavy fraction primarily comprising the oil fraction.

Systems and methods for separation of hydrocarbon containing fluids are provided. More particularly, the disclosure is relevant to separating fluids having a gas phase, a hydrocarbon liquid phase, and an aqueous liquid phase using indirect heating. In general, the system uses a first gas separation followed by pressure reduction and then a second gas separation. Indirect follows the second gas separation and then three-phase separation.

A subsea production unit for subsea treatment of oil has a frame that supports an onboard multiphase separation system for separating gas and water from a wellstream containing oil. The subsea production unit also includes an onboard water treatment system for cleaning oil from water that is produced by the separation system.

A wastewater management system has a container with the first chamber and a second chamber therein, a diverter valve having an inlet and a first outlet, a holding tank interconnected to the first outlet of the diverter valve, and a controller connected to the diverter valve so as to move the diverter valve to the first position. The first outlet is directed to the first chamber. The inlet of the diverter valve is adapted to receive wastewater from a location remote from the container. The inlet is connected to the first outlet in the first position. The diverter valve can be a three-way valve having a first outlet directed to the first chamber and a second outlet directed to a second chamber. The controller moves the diverter valve between first and second outlets.
