Inlet and outlet connections of a well manifold connect to integrated piping of a unitary vessel on a skid. The unitary vessel defines an interior separated into two chambers by a barrier. One chamber has a test inlet for well testing operation, and the other chamber has a production inlet for production operation. Each of the chambers is in communication with a gas outlet for gas, a water outlet for water, and a condensate outlet for condensate. Each of the chambers has a weir plate disposed in the chamber and separating the water outlet on a waterside of the weir plate from the condensate outlet on a condensate-side of the weir plate adjacent the barrier. During use, the second chamber can be isolated so well testing operation can be performed using the first chamber. Also, the first chamber can be isolated so production operation can be performed using the second chamber.

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.

A crude oil desalter unit includes a settler, an inlet manifold fluidly coupled to the settler, and one or more inlet distributors extending from the inlet manifold to discharge a water-in-oil emulsion into the settler. Each inlet distributor includes a riser having a first end, a second end, and an inner flowpath extending between the first and second ends, wherein the riser is coupled to the inlet manifold at the first end, one or more outlet nozzles provided at the second end and in fluid communication with the inner flowpath, and a static mixer positioned within the inner flowpath and defining one or more helical pathways operable to induce rotational flow to a fluid flowing within the inner flowpath.

Tank for holding contents which can separate into different phases, said tank comprising at least two outlet pipes each provided through a bottom of the tank with a first end of the outlet pipes provided outside the tank and a second end provided inside the tank, the second ends of the at least two outlet pipes being provided at different heights within the tank.

A variable oil field fluid treatment system and method of use which utilizes a pump, a desanding hydrocyclone, and/or a non-consumable or consumable mechanical solids filter, a membrane filtration unit, a pump, a granular carbon filter, and/or combinations therein.

Systems and techniques for demulsifier automation of the wet crude handling facilities can include a computer-implemented method. Demulsifier automation parameters for automating demulsifier injection points of a wet crude handling facility are determined. The determining includes performing a data convolution and a smoothening of inlet demulsifier automation parameters. Performing the demulsifier automation of the wet crude handling facility, includes, for each demulsifier, the following: A current state of the demulsifier is identified based on the demulsifier automation parameters. Demulsifier calculation input parameters are determined, including performing a convolution and a smoothening of the demulsifier calculation input parameters. A demulsifier dosage rate is calculated using the determined demulsifier calculation input parameters. A state dependent dosage multiplication factor is applied to the demulsifier based on the current state based on the calculated demulsifier dosage rate.

Devices, systems, and methods for separating a vapor from a gas are disclosed. A gas is passed through a direct-contact exchanger. The exchanger using a contact liquid to cool the gas. The gas comprises a vapor. A portion of the vapor is condensed as the gas passes through the direct-contact exchanger, producing a product liquid and a vapor-depleted gas. The product liquid is immiscible in the contact liquid. The product liquid is gravity settled from the contact liquid such that the contact liquid and the product liquid separate in the direct-contact exchanger.

A process for separating a mixture of components is disclosed. A liquid mixture is provided to a separation vessel substantially near a temperature at which a product component freezes. The liquid mixture comprises the product component and a carrier component. The product component and the carrier component are essentially immiscible substantially near the temperature. The liquid mixture is separated into two or more phases, the two or more phases comprising a product component-rich liquid phase and a product component-depleted liquid phase. In this manner, a mixture of components is separated.

A filter controller which comprises a manifold and at least one filter assembly. The manifold comprises a plurality of portholes and channels into and through which a fluid, such as, e.g., a fuel, may flow. The filter assembly comprises an upper filter subassembly and a lower filter subassembly. The filter assembly can be fitted directly onto the manifold without the use of pipes and fittings and such that the filter assembly is in fluid communication with the portholes and channels necessary for effective filtering, polishing, and flow of the fluid through the system and through the assembly into which the system is integrated.
