To provide a gas-liquid separator of a water electrolysis system, comprising: a liquid feeding atomizer and a gas-liquid separation chamber, wherein the liquid feeding atomizer includes a liquid feeding pressurized tube; and an atomizing spray head, in which the atomizing spray head converts a gas-liquid mixed liquor after pressurized by the liquid feeding pressurized tube into a mist droplet gas-liquid mixture. The gas-liquid separation chamber comprises a spiral flowing way, and the spiral flowing way extends the time that the mist droplet gas-liquid mixture spraying into the gas-liquid separation chamber flows downwards to the bottom of the gas-liquid separation chamber; an ultrasonic oscillation mechanism; a stirrer; an internal reservoir; and a filter mechanism, which performs the gas-liquid separation for unbroken bubbles in the mist droplet gas-liquid mixture through the pore difference.

A method of separating a flow of multi-phase fluid includes directing the flow through the inlet opening of an enclosed tubular body comprising a tubular sidewall with opposed end walls, one or more axial outlet apertures formed through the end walls, and one or more radial outlet apertures formed through the tubular sidewall at locations spaced from the inlet opening. The method also includes directing the flow of multi-phase fluid onto one or more swirl plates positioned between the inlet opening and the outlet apertures, with the swirl plates having angled surfaces configured to impart a cyclonic motion to the flow so as to initiate separation of the constituents of the multi-phase. The method further includes directing the gas constituent axially outward through the axial outlet aperture and directing the oil constituent and the water constituent radially outward from the tubular body through the one or more radial outlet apertures.

Disclosed is an external circulating slurry reactive crystallizer, including a riser, a degassing zone and a downcomer. A lower end of the riser is communicated with a gas inlet pipe, a liquid inlet pipe and a solid feeding pipe, while an upper end of the riser is communicated with a lower end of the degassing zone. An upper end of the downcomer is integrally fixed to a sidewall of the degassing zone. At least one hydrocyclone is arranged at a lower end of the downcomer. The hydrocyclone is provided with an overflow port at an upper end thereof and an underflow port and a valve at a lower end thereof. The overflow port is communicated with the riser. The crystallizer can simultaneously realize reaction, crystallization and separation for continuous production with low cost, regulating and controlling the particle size distribution and morphology of crystals.

Systems and methods for crude oil separations including degassing, dewatering, desalting, and stabilization. One method includes separating crude oil into a crude oil off-gas and a partially degassed crude oil output; compressing the crude oil off-gas; applying the compressed crude oil off-gas for indirect heating through reboilers of the partially degassed crude oil output; and directly mixing with the crude oil a compressed atmospheric pressure gas. In some embodiments, multiple reboilers are used. In some embodiments, heat exchangers are used. Aftercoolers are used after the compressor to cool the gas; knockout drums are used after the coolers to separate liquids.

A method for continuously removing a particular type of gas molecules (“gas molecules”) from a gas stream includes selecting a liquid having an affinity for the gas molecules to be removed, and providing the selected liquid to each of a first and second mat, each mat formed from a plurality of fibers having the ability to retain the selected liquid within longitudinally extending channels having longitudinally extending openings against moving into the space between the individual fibers, the mats in fluid communication therebetween with the selected liquid. The method includes directing the gas stream through a portion of the first mat into contact with the selected liquid along the longitudinally extending openings whereby the selected liquid absorbs the gas molecules, and directing a second gas through a portion of the second mat so that the gas molecules, absorbed by and disbursed throughout the selected liquid, are stripped and carried away.

Method includes recovering a stimulating fluid, which includes transferring working fluid having the stimulating fluid from an operating site (102) to a current temporary processing facility (TPF) (110) that is located remotely with respect to the operating site in the geographical region. After purifying the working fluid at the current TPF (110), thereby providing the stimulating fluid, the stimulating fluid is transferred from the current TPF to an injection site (103) that is located remotely with respect to the current TPF and the operating site. The method also includes transporting fluid-handling equipment after a designated condition has been satisfied. The fluid-handling equipment is transported from the current TPF (110) to a new TPF (110). The recovering of the stimulating fluid, the transferring of the stimulating fluid, and the transporting of the fluid-handling equipment is repeated a plurality of times. The current and new TPFs are at different locations within the geographical region.

A flow back system for separating solids from a slurry recovered from a hydrocarbon well. The system includes a V-shaped tank with a first series of baffles configured to cause the settling of solids that are moved by a shaftless auger to a conduit fluidly connected to hydrocyclones mounted over a linear shaker. The overflow from the hydrocyclones is discharged through a second conduit back into the tank for processing by a second series of baffles resulting in a clean effluent. The clean effluent is recirculated in the well.

A permeate device includes at least one non-porous, gas permeable element configured for contact with a liquid flow and at least one element fabricated from a porous material configured to permit gas flow therethrough. The permeate device may include a vacuum chamber that surrounds an operative portion of a permeation zone. A method for processing a liquid flow to remove entrained gas includes providing a liquid flow that includes an initial level of entrained gas, delivering the liquid flow to a permeate device, wherein the permeate device includes (i) at least one non-porous, gas permeable element configured for direct contact with the flow; and (ii) at least one element fabricated at least in part from a porous material configured so as to permit gas flow therethrough, and applying a negative pressure to the permeate device to draw entrained gas from the flow within an operative portion of the permeate device.

A system for removing particulate matter from a multiphase stream comprising gas, liquid and the particulate matter. The system comprises a first vessel for receiving the multiphase stream and separating a majority of gas from the multiphase stream and collecting a slurry of liquid and particulate matter; a second vessel for receiving the slurry and causing separation of the particulate matter from the liquid and for generating a pressure head of liquid against the particulate matter; a third vessel for receiving the particulate matter from the second vessel and collecting the particulate matter until a pre-determined mass or volume of particulate matter is collected; and an outlet in the third vessel for conveying the particulate matter out of the third vessel.
