  • Patent number: 11203560
    Abstract: A MEG reclamation process includes the step of increasing above 2,000 ppm the divalent metal salts concentration of a rich (wet) MEG feed stream flowing into a precipitator. The increasing step includes routing a salts-saturated MEG slipstream from the flash separator it to the precipitator. The slipstream may be mixed with a fresh water feed stream, a portion of the rich MEG feed stream, or some combination of the two. The rich MEG feed stream also may be split into two streams, with a portion of the stream being heated and routed to the flash separator and the other portion being combined as above with the removed slipstream. The process can be performed on the slipstream after dilution and prior to entering the precipitator or after being loaded into the precipitator. Removal of the insoluble salts may be done in either a batch or continuous mode.

  • Patent number: 10927308
    Abstract: 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.

  • Patent number: 10870801
    Abstract: 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® 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.

  • Patent number: 10677366
    Abstract: A system and process for intermittently venting combustible gas (c-gas) from a continuous source to the atmosphere are presented. The system may include a c-gas storage tank, an admission valve located upstream of the c-gas storage tank for regulating the flow of c-gas from the continuous source to the storage tank; an inert gas storage tank and an inert gas valve for regulating flow of inert gas to the c-gas storage tank, the inert gas diluting the c-gas within the c-gas storage tank below a flammable level; a vent valve for atmospheric venting located downstream of the c-gas storage tank, and a PIC that opens the vent valve when pressure in the c-gas storage tank reaches a pre-determined PIC vent point. The system may also include an auxiliary system to receive and vent c-gas diluted below the flammable level while the primary admission valve is closed.

  • Publication number: 20200071250
    Abstract: A system and process for removing divalent cations from a rich MEG feed stream is presented. An ion exchange bed containing a cation exchange resin adsorbs the divalent cations in the rich MEG feed stream as it flows through the ion exchange bed. After the divalent ions have been removed, the feed stream flows through a flash separator and a distillation column to reclaim MEG. Alternatively, the feed stream flows through a distillation column to regenerate MEG. The spent cation exchange resin may be regenerated in place using a regeneration brine comprised of sodium chloride and water. After use, the regeneration brine may be disposed as waste or recycled to the brine storage tank and re-used to regenerate the cation exchange resin.

  • Patent number: 10301190
    Abstract: A method to remove oil from an oily water stream includes the step of pressure controlling a release of dissolved gases from the stream as the stream passes through two or more stages of gas flotation treatment. The operating pressure of the first stage of flotation treatment is purposefully reduced relative to that of an upstream unit so that a certain controlled percent volume of dissolved gases is released. The operating pressure of the second stage of flotation treatment is then purposefully reduced relative to that of the first stage so that another controlled percent volume of dissolved gases is released. Any subsequent flotation treatment stage is at a lower operating pressure than that of the previous stage so that the subsequent treatment stage releases a controlled percent volume of dissolved gases. By controlling the operating pressure in this way, overall separation performance is improved.
