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 experimental device and method for testing foam fluid properties and defoaming separation effects, the experimental device including a foam generation module configured to generate a foam fluid, an experimental loop configured to transport the foam fluid and enable the foam fluid to sufficiently develop in a loop, a foam property test module configured to test foam fluid properties, a foam separation processing module configured to separate foam from fluid and gas, and a defoaming result evaluation module configured to test and evaluate defoaming results. In the method, different foam fluids are generated in the foam generation module and are transported to the foam property test module and different foam separation processing modules through the experimental loop, and the foam properties of the foam fluids and defoaming separation effects are measured by the foam property test module and the defoaming result evaluation module connected to the foam separation processing module.

A wellbore gas separator having a pair of helical ramps. The separator ingests a liquid-gas solution, and a pump draws the solution into a first course between the pair of ramps. As centrifugal force is imparted upon the solution prior to the pump inlet, gas is forced out of solution. The liquid portions of the solution may fall into a dead space prior to the pump inlet. Gaseous portions enter into a second course between the pair of ramps and escapes, unimpeded, up the separator before being released into an annulus of a wellbore.

Systems and methods for crude oil separations including degassing, dewatering, desalting, and stabilization, one method including 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 of the partially degassed crude oil output; further heating the partially degassed crude oil output indirectly with compressed low pressure gas; directly mixing with the partially degassed crude oil output a compressed atmospheric pressure gas; separating from the partially degassed crude oil output a low pressure gas for use in the step of further heating; and separating from the partially degassed crude oil output an atmospheric pressure gas for use in the step of directly mixing.

An annular axial mixing system for combined gas and liquid flow. The system includes a gas-liquid separator to separate a multiphase gas and liquid into a gas flow and a liquid flow. A lower leg in communication with the gas-liquid separator is configured to receive liquid flow. An upper leg in communication with the gas-liquid separator is configured to receive gas flow. An annular mixing chamber receives gas from the upper leg. A static liquid chamber, at least a portion of which is within the mixing chamber, is in communication with the lower leg and includes perforations therein to receive gas bubbles from the gas in the annular mixing section chamber in order to mix the flows.

An inline microgravity air trap device includes an elongate air trap chamber, the air trap chamber having a blind end, an opposite air outlet end containing a gas egress opening, a fluid inlet port connecting to a pressurized fluid supply, a fluid outlet port connecting the air trap chamber to a fluid delivery destination, a filter forming a tube having an interior, a first end at the blind end of the air trap chamber and a second end at the gas egress opening, and a structural insert in the interior of the tube, having a first insert end located at the blind end, and a second insert end located the air outlet end, where the chamber is formed to direct fluid from the pressurized fluid supply to accelerate centrifugally around the filter, forcing gas contained in the fluid to pass through the filter into the interior of the tube.

Pumping of wellbore fluid to a surface may have a detrimental effect on the pump performance due to high gas concentrations in the fluid. A pump system that utilizes a helix gas separator provides greater pump efficiency by effectively removing the gas phase of the fluid. The wellbore fluid received at a pump system is directed from an intake to a gas separator that utilizes a stationary auger. The stationary auger induces rotational motion of the wellbore fluid causing the wellbore fluid to separate into a gas phase and a liquid phase. The stationary auger utilizes a tapered diameter and an opening between one or more helixes or vanes to separate a gas phase more efficiently from a liquid phase of a fluid.

A gas dissolved liquid manufacturing device includes: a pump configured to pressurize a liquid; a pipe communicating with the pump; a nozzle disposed in the pipe, the nozzle being configured to generate micro bubbles using a supplied gas; and a gas-liquid separation tank whose upper part communicates with the pipe, the gas-liquid separation tank being configured to separate a gas-liquid mixture generated by the nozzle into a gas and a liquid.

A multi-phase separation apparatus shapes a fluid stream in a flow shaping line having a plurality of descending, vertically stacked curvilinear loops disposed along a fluid vessel vertical axis, stratifying the fluid stream into a primarily liquid component and a primarily gaseous component. At a point below plurality of loops, the primarily gaseous component is bled off from the primary liquid component. The primarily gaseous component may be introduced into a vortex cluster to further separate liquid entrained in the gaseous component, which separated liquid may then be combined back with the primarily liquid component. The vertically stacked curvilinear loops may be disposed within a fluid vessel to protect and insulate the loops or may be disposed about the exterior of the vessel. The vortex cluster system may be positioned within the vessel and may employ vortex tubes deployed along either a linear flow channel or a spiral flow channel.

An oil tank system (100) for a gas turbine engine is provided. The oil tank system (100) includes an oil tank (102) having an upper tank portion (112) and a lower tank portion (114), a waisted section (118) being provided between the upper tank portion (112) and the lower tank portion (114). Oil is received by a de-aerator (104) of the system (100) which supplies de-aerated oil to the upper tank portion (112). The waisted section (118) includes an upper face (119) configured to catch oil drips from above the waisted section (118) and to guide oil to a lower face (121) of the waisted section (118).
