A gas separator for removing suspended gas from a fluid is provided. A plurality of pipes define an overall fluid pathway that includes: a first fluid path from the first fluid chamber to the third fluid chamber, the first fluid path passing through the second fluid chamber without interacting with contents the second fluid chamber, the first fluid pathway being narrower than the first fluid chamber such that fluid flows through the first fluid pathway faster than through the first fluid chamber; a second fluid path from the third fluid chamber to the second fluid chamber, the second fluid path extending at least partially along an exterior wall of the second and third fluid chamber; and a third fluid path from the second fluid chamber to the fourth fluid chamber, the third path passing through the second fluid chamber without interacting with content of the second fluid chamber.

A gas and liquid separation system could be said to have a passage with an inlet connected to receive a mixed gas and liquid flow. An air separation tube extends into the passage at a location downstream of where the inlet is connected with an upstream tube end upstream in the passage relative to a downstream tube end. The upstream tube end provides an obstruction to the mixed gas and liquid flow, to cause separation of the gas from the mixed gas and liquid flow. A liquid tube is connected to the passage at a location downstream of the air separation tube.

The invention relates to a method for degassing a fluid comprising the following steps: supplying, at the inlet of a reactor comprising at least one microfluidic conduit, a fluid which can comprise at least one dissolved gas; then causing the fluid to flow through the reactor, the at least one conduit comprising a portion having a reduced hydraulic diameter, and the flow being set such that bubbles are generated by micro-cavitation, the fluid then comprising a liquid phase and a gas phase, then allowing the at least partial transfer of the at least one dissolved gas present in the fluid of the liquid phase to the gas phase; separating the liquid phase and the gas phase; and recovering the liquid phase to obtain the degassed fluid, the method not involving the application of ultrasound to the fluid between the step in which the fluid is supplied to the reactor and the step of separating the liquid phase and the gas phase.

An air bleeder includes a branch, a lubricant supply conduit, and a return conduit. Lubricant stored in a tank is to be supplied to a valve provided in a machine tool via the lubricant supply conduit. The lubricant supply conduit includes a first supply conduit, and a second supply conduit. The first supply conduit connects the branch and the tank. The second supply conduit connects the branch at a first connecting position and the valve. The return conduit connects the tank and the branch at a second connecting position higher than the first connecting position in a height direction along a height of the air bleeder to return lubricant to the tank and to remove air from lubricant in the lubricant supply conduit.

A gas-liquid separation device includes a heat exchange member having a heat exchange tube spirally wound around a first cylinder body. The heat exchange tube includes a first flow passage, a tube wall surrounding the first flow passage, and a first extension portion protruding from the tube wall. A second flow passage is formed between the first cylinder body, the second cylinder body, and the heat exchange tube. The first extension portion is located in the second flow passage. A heat exchange area between the heat exchange tube and a fluid in the second flow passage is increased. The heat exchange effect between a fluid in the first flow passage and the fluid in the second flow passage is improved. A thermal management system having the gas-liquid separation device is also disclosed.

A gas separator for separating a multiphase medium containing a gas and a liquid includes a tubular basic unit having a longitudinal axis, an intake for a gaseous medium, a liquid outlet and a gas outlet. The tubular basic unit has an intake region and a discharge region. The gas separator includes, between the intake region and the discharge region, a weir having a guiding surface, over which the medium can flow to form a shallow water region. The gas contained in the medium can escape from the medium in the shallow water region and be led away from the gas separator through the gas outlet. The disclosure is also directed to an apparatus for registering flow of at least one component of a multiphase medium.

Disclosed is an expansion tank, including a cavity structure and a degassing flow channel, where the degassing flow channel is arranged on the expansion tank, a flow guide hole is provided on the degassing flow channel, and the degassing flow channel is in communication with the cavity structure by means of the flow guide hole; and a liquid inlet and a liquid outlet are provided at two ends of the degassing flow channel respectively and are used for being in communication with a vehicle cooling system. The expansion tank of the present application satisfies a degassing requirement, reduces usage amount of pipelines and pipe clamps, and reduces weight of a vehicle body.

A centrifugal coolant gas separator (CCGS) for a cooling system is provided. In one example configuration, the CCGS includes a main body defining a cyclone separator chamber therein configured to separate a flow of coolant into gas and liquid coolant, a liquid outlet formed in the main body and configured to receive the separated liquid coolant from the cyclone separator chamber, and a gas outlet formed in the main body and configured to receive the separated gas from the cyclone separator chamber. A first inlet is configured to receive a forced flow of a first portion of a coolant flow, and a second inlet is configured to receive a second portion of the coolant flow. The forced first portion of coolant flow induces the second portion of coolant flow into the cyclone separator chamber for subsequent gas and liquid coolant separation of the first and second portions of coolant flow.

An exhaust gas flow control system for an oxygenator of an extracorporeal ventilation system connected to an oxygenation gas supply line and to an exhaust line for removal of exhaust gas comprises a flow control path, a pressure control path, an exhaust flow regulator responsive to the controller, and an exhaust gas pressure regulator responsive to a controller configured to maintain a pre-determined pressure level in the exhaust line. This provides a better degree of control over the pressure across the oxygenator from oxygenation gas inlet to exhaust.

A treatment process for remediating; contaminants in a mixture of contaminated fluids, including at least one liquid fluid and at least one gaseous fluid, includes the steps of: preparing a treatment composition containing at least 80 volume % of an aqueous solution containing at least one hydroxide compound at a collective concentration of 35-55 weight percent, and at least one organic acid selected from the group consisting of fulvic acid and humic acid at a collective concentration of 0.1-5 wt % of the treatment composition; adding a dosage of the treatment composition to a mixture of contaminated fluids including a liquid portion and a gaseous portion; and allowing the treatment composition to react with the mixture of contaminated fluids for at least 10 minutes. A pH of the treatment composition is at least 12.0
