  • Patent number: 11058968
    Abstract: Systems and methods for removing solids from a process stream being fed into a flash separator include a solids fluidization device and a solids removal device. The solids fluidization device at the bottom end of the fluid column of the flash separator introduces a swirling motive fluid within the fluid column, while the solids removal device located above the solids fluidization device removes the slurry created by the swirling motive fluid. Systems and methods for fluidizing solids in the fluid column of a flash separator include a solids fluidization device that introduces a swirling motive fluid within the fluid column, means to limit the upward movement of the swirling motive fluid, such as a valve, and removing the solid slurry produced by the swirling motive fluid.

    Abstract: A power supply device includes a power conversion circuit configured to generate an output voltage from an input voltage, and a controller coupled to the power conversion circuit and configured to control the power conversion circuit to generate the output voltage for causing or enhancing coalescence of a multi-phase liquid mixture when the output voltage is applied to the multi-phase liquid mixture. The controller is configured to control generation of the output voltage in accordance with a synchronization signal. The controller is further configured to generate the synchronization signal and transmit the synchronization signal to another power supply device, or receive the synchronization signal from another power supply device.

  • 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: 10913013
    Abstract: A system and method for processing interface emulsion, water, and solids contained within a separator vessel that comprises the steps of continually extracting those components from the vessel and then passing them through a gas flotation cell. The cell, which is preferably a vertical induced gas flotation cell, separates the oil and water contained in the interface emulsion and discharges recovered oil from an upper portion of the cell and treated water from a bottom portion of the cell. The recovered oil and treated water may be further processed and recycled to the vessel or sent elsewhere. The treated water may also be recycled to the cell or sent to a process sewer. Fuel gas residing in an upper portion of the cell may be cooled and passed through a splitter. All the steps of occur in a closed system with no air emissions.

  • Publication number: 20200399735
    Abstract: Apparatus and methods for lithium extraction from aqueous sources are described herein. Divalent ions are removed using staged membrane separation. The aqueous source is subjected to a solvent extraction process that extracts lithium. Aqueous and organic phases of streams produced by the solvent extraction process are separated using electrical and/or gas flotation separation. The solvent is de-complexed to unload lithium. Streams produced by the de-complexing may be subjected to electrical and/or gas flotation separation. Solvent de-complexing can be performed using an electrical separator. Aqueous streams are pH adjusted for return to the environment.

    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.

  • Publication number: 20190203933
    Abstract: Disclosed herein are systems, apparatuses, and methods for using a sensed combustion zone temperature to continuously control combustion of a first (main) gas within an enclosed combustor. The combustor is in fluid communication with a first gas line carrying the first gas, a second gas line independent of the first gas line carrying a second (assist) gas having a higher heating value than the first gas, and air dampers providing draft or assist air. The first gas may be vapors from a production source or tank. A computer control system monitors the combustion zone temperature of the enclosed combustor as sensed by a sensor in electronic communication with the computer control system and controls the combustion zone temperature by changing a condition of a first gas line valve of the first gas line, a second gas line valve of the second gas line, and the air dampers.
