The present invention relates to a tubular oil separator providing separation of respective fluid components mixed in fluids from oil wells, wherein the tubular oil separator A is arranged to mitigate problems related to turbulence and possible non-Newtonian fluid behaviors of fluid components mixed in the fluids from the oil wells in the oil separator. The invention further relates to a method of operating a separator. Moreover the invention relates to a system of multiple separators. Inventive aspects of the separator comprises an elongated outer, closed tubular section and an elongated, inner tubular section, which is closed in one end and open in another end, —where the inner tubular section is arranged inside the outer tubular section, —and where oil well substances are introduced into the open end of the inner tubular section via a tube feed section passing through the outer tubular section and into the inner tubular section, —and where the inner tubular section comprises multiple, elongated and parallel slots arranged in a longitudinal direction of the inner tubular section in a circumferential manner, —where the inclination of the separator facilitates separation of the oil well substances into lower density substances and higher density substances, —where the lower density substances by buoyancy drift upward through the slots and exit via an upper outlet in the outer tubular section and higher density substances sink downward through the slots and by gravitation exit via a lower outlet in the outer tubular section.

Separation of particles or droplets from a host fluid may be achieved using a transducer and/or reflector that is a thin, non-planar structure. The thin non-planar structure improves operation of an acoustic standing wave generated by an acoustic transducer. The structure may operate as a pressure release boundary and may be constructed as plastic film.

A disclosed example embodiment of a fluid extraction system includes a fluid circuit fluidly coupled to a source of a fluid and configured to receive a fluid sample from the source, and a fluid separator arranged in the fluid circuit and configured to receive the fluid sample. The fluid separator includes a body that defines at least one fluid inlet, a flow chamber defined within the body, and is configured to receive and spin the fluid sample from the at least one fluid inlet. The fluid sample spirals inward and forms a vortex, and gases entrained within the fluid sample separate and migrate toward a center of the vortex. An outlet defined in the flow chamber provides a gas outlet that entrains and removes the gases and a liquid outlet receives and removes a remaining portion of the fluid sample.

A device which includes a pulse dampener and a degasser or de-bubbler. The device includes a fluid flow path and a fluid chamber located within the device. In addition, the device includes a pulse dampening membrane for dampening pulses in the fluid as it flows through the device. The device also includes a degassing membrane for degassing the fluid as it flows through the device, and/or a de-bubbling membrane for removing gas bubbles from the fluid as it flows through the device. The degassing or de-bubbling membrane can be separate and distinct from the dampening membrane. The de-bubbling membrane can be in addition to or in place of the degassing membrane in some embodiments.

A nuclear power plant includes a nuclear reactor and a reactor coolant circuit containing a reactor coolant. The nuclear power plant further includes a degasification system (2) for the reactor coolant. The degasification system (2) is an ultrasonic degasification system comprising a sonotrode cluster (11) with at least one sonotrode (10) arranged in a line of the reactor coolant circuit or in a line which is fluidically connected to the reactor coolant circuit.

A system can include a multi-material fluid having a mixture of a first material and a second material. The system can also include a first vessel into which the multi-material fluid is disposed. The system can further include a first sonication device disposed, at least in part, in the multi-material fluid in the first vessel. The first sonication device, when operating, can emit ultrasound waves into the multi-material fluid. The ultrasound waves separate the first material and the second material from each other in the first vessel.

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 degasser for at least partially degassing a gas-containing liquid, in particular for a sample separation device, includes a liquid accommodation volume for accommodating the gas-containing liquid during degassing, a negative pressure chamber in which a negative pressure, compared to the liquid accommodation volume, is to be generated, a gas permeable membrane separating the liquid accommodation volume from the negative pressure chamber and arranged so that ultrasound forces at least part of gas of the gas-containing liquid to move through the membrane by a combination of the negative pressure and the ultrasound, and an ultrasound source including an electroactive material and configured for generating ultrasound for actuating the gas-containing liquid and/or the gas permeable membrane.
