A method is described herein, comprising registering an event at a first processing unit of a processing facility comprising a plurality of processing units, using a coincidence probability array and an event probability to identify a second processing unit of the plurality of processing units based on the event, determining whether the second processing unit experienced a coincident event, if the second processing unit experienced a coincident event, remediating a condition of the second processing unit that caused the coincident event, and updating the coincidence probability array based on the event.

Equipment failure diagnostics using Bayesian inference

A process train for a floating production storage and offloading installation includes a crude oil storage tank equipped with at least one set of electrostatic internals. The set of electrostatic internals are arranged to provide a treatment flow path within the crude oil storage tank oblique to a longitudinal centerline of the crude oil storage tank and through an electric field provided by the set of electrostatic internals. Employing these electrostatic internals within the tank permits an allowable inlet water content into the tank of up to 80%, significantly reducing the required topside processing equipment. The process and system also includes, upstream of the tank, two separator vessels arranged in parallel so each receives a portion of an incoming oil-and-water stream, a flash vessel arranged downstream of the two separator vessels, and a degasser vessel. Downstream of the crude oil storage tank is an electrostatic treater.

Electrostatic technology system and process to dehydrate crude oil in a crude oil storage tank of a floating production storage and offloading installation

A system and method for dehydrating crude oil on a floating production storage and offloading installation include a separator vessel to receive an incoming produced water stream, followed by a flash vessel, a treatment block, a crude oil storage tank, and an electrostatic treater. The treatment block includes a low pressure degasser followed by a compact electrostatic separator pre-treater or a compact electrostatic separator pre-treater followed by a low pressure degasser. The flash vessel and/or the low pressure degasser may employ an inlet cyclonic distributor and demisting cyclones, while the electrostatic treater may employ DUAL FREQUENCY&#xae; technology. The separator vessel may be a single horizontal two-phase separator/degasser or two vertical two-phase separator/degassers that operate in parallel with each receiving approximately 50 percent of the incoming produced water stream. The final outlet stream preferably contains no more than 0.5 BS&W and 285 milligrams per liter salt.

Topside oil production equipment system for reduction in space and weight

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.

System to reduce interface emulsion layer formation in an electrostatic dehydrator or desalter vessel through use of a low voltage electrostatic interface emulsion treatment system inside the vessel

A process train for a floating production storage and offloading installation includes a crude oil storage tank that is equipped with at least one electrostatic separator configured to subject the produced stream that enters the tank to an electric field. The electrostatic separator may include two inclined vessels containing electrostatic internals and in fluid communication with one another. Employing electrostatic separators within the tank can permit an allowable inlet water content into the tank of up to 80%, significantly reducing the required topside processing equipment.

Crude oil storage tank with electrostatic internals to dehydrate crude oil within a process train of a floating production storage and offloading installation

A process train for a floating production storage and offloading installation includes a crude oil storage tank that is equipped with at least one set of electrostatic internals arranged to provide a treatment flow path isolated from a surrounding volume of the electrostatic separator section of the tank. An oil-and-water stream or mixture entering the set of electrostatic internals travels along the treatment flow path and is subjected to an electric field. The treatment flow path is in an upwardly direction toward the oil outlet section and in a downwardly opposite direction toward the water outlet section of the tank. Employing electrostatic internals within the tank permits an allowable inlet water content into the tank of up to 80%, significantly reducing the required topside processing equipment.

A method and system for controlling an interface emulsion layer and mud layer within a desalter vessel includes injecting a water flow through a plurality of nozzles arranged about a piping circuit located in the brine water layer. Each nozzle is oriented toward an interior space of the desalter vessel and is arranged oblique to the piping circuit. The water flow through the plurality of nozzles causes a horizontal and vertical rotation of a volume of water that is effective for suspending solids in the water and promoting a collapse of the interface emulsion layer. The water velocity through each nozzle, which may be a recycled water flow, is preferably in a range of 1 to 3 fpm and each nozzle is preferably oriented at an angle of about 15&#xb0; and 60&#xb0; in a horizontal plane and a downward angle of about 15&#xb0; and 60&#xb0; in a vertical plane.
