Abstract:
A static desalter simulator apparatus has a housing for containing a liquid bath and a rack disposed within the housing. The rack is formed of at least two substantially parallel plates separable by a plurality of spacers. An electric field is generatable between the plates, and at least one of the plates includes at least one recess. The apparatus also includes at least one mixing tube for containing an oil-water emulsion, which is positionable within at least one of the recesses. A controller is operatively connected to a mixing tube. An imaging device for generating a digital image or video during a demulsification process is in a mixing tube.
Abstract:
A permanent subsea sampling and analysis system is integrated into a replaceable equipment module for a choke valve of a subsea production well. The analysis system is self-contained, and separates a sample into liquid fractions consisting of crude oil, condensate and produced water and then measures the salinity of the water as well as the volumetric ratio between the liquid fractions all in the same sampling container.
Abstract:
The present invention relates to a device for separating insoluble components from a liquid, which device essentially consists of a housing (2) having an inlet opening and an outlet opening (3) and, disposed between said inlet opening and said outlet opening, a packet (7) consisting of a number of spaced-apart parallel plates, which housing makes a certain angle with the horizontal, and means for supplying the liquid to the housing and for discharging the insoluble components and the purified liquid, which plates form separate flow channels, through which flow channels the liquid flows, whereby the plates have a surface which can be electrically charged.
Abstract:
An apparatus (100) for separating a plurality of components (A, B, C, E) in a fluid includes an optically transparent sorting channel (110) having a first inlet (120) for a first flow (W) and a second inlet (120) for a second flow (X), and a first outlet (130) for the first flow (W) and a second outlet (130) for the second flow (X); and a holographic optical trap system (210) coupled to the optically transparent sorting channel (200) for selectively moving a first component (A) of the plurality of components (A, B, C, E) in the first flow (W) into the second flow (X) to form an enriched second flow (X).
Abstract:
An electrostatic treating apparatus comprises a tank 1 containing an insulating solvent A in which a pair of electrodes 4 is arranged and a liquid 2 is introduced from an inlet 3 and electrostatically treated. A guide plate for guiding treated water to the upper side of a pocket 7 is provided at the lower part of the aqueous layer B formed above the upper edge of the inner wall 5 of the pocket 7 and plural baffle plates 18 having openings at the upper part and the lower part alternately are equipped vertically at given intervals between the guide plate 8 and the lid of the tank 1, and an adsorbing agent vessel 19 can be equipped between the baffle plates 18. The treated water which goes up from an opening 9 between the outer side wall 6 of the pocket 7 and the guide plate 8 is passed through the adsorbing agent vessel 19 to be introduced to a discharge outlet 12. Further the electrodes 4 and the main parts of the guide plate 8 are hung and fixed to the lid D of the tank 1 so that they can be equipped to the tank 1 together with the lid D.
Abstract:
A process for separating an emulsion into separate and easily recoverable phases is disclosed. The process comprises exposing said emulsion, comprising a discontinuous phase and a non-conducting continuous phase, to an electric field thereby effecting coalescence of said discontinuous phase into droplets of a size for effective gravitation from the continuous phase, where the discontinuous phase and the continuous phase have different dielectric constants and densities and at least one of the phases comprise a silicon containing compound or a silicon containing polymer. This process is especially useful for separating emulsions where the discontinuous phase is an aqueous acid solution and the continuous phase is diorganopolysiloxane.
Abstract:
A system for removing brine from oil well production (12) in which fresh water (50) or less saline water (50) is passed in counterflow to the oil well production (12) through electric fields established between a plurality of composite electrodes (26). The electrodes (26) are of a laminar construction having a centrally located conductive member (30) surrounded by an electrically nonconductive region (28). With a nonmodulated voltate supply (144) connected to conductive member (30) a plurality of electric fields, some having uniform gradient and others having nonuniform gradient, are established between adjacent composite electrodes (26) in the direction of flow of both the oil well production (12) and the dilution water (50). Composite grids (26) have an inherent current regulating characteristic that reduces the tendency for arcing and suppresses sustained arcing should an arc occur.
Abstract:
Free excess charge which is net unipolar is introduced, preferably by charge injection, into the continuous phase. The charge transfers, through the continuous phase, to the dispersed phase and an induced electric field is thereby set up which drives the charged dispersed phase to one or more collector surfaces in contact with the continuous phase. According to different applications, the collector surfaces can take the form of the inside surface of a separation vessel (6) and/or beads (33) of low conductivity or porous material (24). An important application is to the dewaxing and dewatering of lube oil.
Abstract:
A system and method for dehydrating crude oil on a floating production storage and offloading installation include a separator vessel (20) to receive an incoming produced water stream (15), followed by a flash vessel (30), a treatment block, a crude oil storage tank (60), and an electrostatic treater (70). The treatment block includes a low pressure degasser (40) followed by a compact electrostatic separator pre-treater (50) or a compact electrostatic separator pre- treater (50) followed by a low pressure degasser (40). The flash vessel (30) and/or the low pressure degasser (40) may employ an inlet cyclonic distributor and demisting cyclones, while the electrostatic treater may employ DUAL FREQUENCY® technology. The separator vessel (20) 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.
