Disclosed is a cooling system comprising a cooling circuit with a deaeration device arranged in the cooling circuit for separation of air bubbles from coolant circulating therein. The deaeration device comprises a deaeration chamber having a coolant inlet connected to a feed pipe of the cooling circuit, a first coolant outlet connected to a coolant pump of the cooling circuit, and a second coolant outlet connected to an expansion tank via a static line. The deaeration chamber has a larger cross-sectional dimension than said feed pipe. The second coolant outlet is located in such a position in relation to the coolant inlet and the first coolant outlet that the coolant flow in the deaeration chamber between the coolant inlet and the first coolant outlet will move migrating air bubbles in the longitudinal direction of the deaeration chamber towards the second coolant outlet.

Disclosed is a cooling system comprising: a first cooling circuit with a first coolant pump; a second cooling circuit with a second coolant pump; an expansion tank provided with an expansion chamber for accumulation of coolant, wherein the expansion chamber is connected to the second cooling circuit to allow the expansion chamber to receive coolant from the second cooling circuit; and a deaeration device arranged in the first cooling circuit for separation of air bubbles from the coolant circulating therein. The deaeration device is located at a lower position than the expansion tank and connected to said expansion chamber via a static line to allow air bubbles separated from the coolant in the deaeration device to migrate upwards in the static line towards the expansion chamber.

The cryogenic device for separating gas fraction from a liquefied natural gas flow carries out a two-stage separation of a gas fraction. The device includes a cylindrical housing provided with an inlet pipeline and an outlet pipeline, and a perforated partition arranged within the housing so as to face the outlet pipeline. The housing has two (upper and lower) portions of cylindrical shape that are connected to each other at an angle α of 135°-170°. There are two additional pipelines on the outside, one of them being used for pressure feed of a gas fraction after the first separation stage into the housing upper portion, and the other additional pipeline being used for extracting a gas fraction after the second separation stage into the gas cavity of a reservoir containing a cryogenic fuel.

A system and method for determining an efficiency of gas extraction. A chamber allows inflow and outflow of the drilling fluid. An amount of gas extracted from a drilling fluid flowing through the chamber at a constant rate during a dynamic process is measured. A dissolution curve is obtained indicative of a gas remaining in the chamber after the dynamic process. An amount drawn from the chamber during a static process subsequent to the dynamic process is measured. An amount of gas from the drilling fluid during the static process is determined from a difference between the amount of gas drawn from the chamber during the static process and an amount of gas indicated by the dissolution curve. The gas extraction efficiency is determined from a ratio of the amount of gas extracted during the static process and the amount of gas extracted during the dynamic process.

A sand separator for capturing solid debris from oil and gas wells includes a spherical, high-pressure vessel adapted to couple downstream of a wellhead. Fluid entering the separator follows a helical path around a vertical separator axis, slowing and separating into water, gas, oil and solid debris, the latter sinking to the bottom. A conical, downwardly opening flue descends from an exit port at the top and terminates in a horizontal, coaxial perimeter. A scalloped, annular collar inside the flue perimeter creates a low barrier to fluid flow into the flue. As fluid constituents circulate toward the flue, they recombine free of sand and rock debris, pass under the flue perimeter and across the collar, slowing further and becoming substantially laminar A fluid dome rises inside the flue with a gas layer above other fluid constituents, permitting the gas to exit the separator through the exit port.

A separation system for separating components of a flow of multi-phase fluid includes an elongate separator vessel oriented on an incline to define a lower inlet end having an inlet for receiving the fluid flow, a raised outlet end, and an inclined top inner surface extending from the inlet end to the outlet end. The system includes a lower weir plate positioned above the inlet end and an upper weir plate positioned below the outlet end having an upper edge defining a liquid level within the separator vessel, thereby allowing a lighter fluid component to flow over the upper edge into a upper section located forwardly of the upper weir plate. The system also includes a clear water pipe with a withdrawal opening positioned below the upper weir plate. The incline of the separator vessel is adjustable in accordance with the composition of the multi-phase fluid.

A device for separating gas bubbles from a liquid flow, having a degassing chamber with an inlet conduit and an outlet conduit for conducting the liquid flow and having a collecting chamber that communicates with the degassing chamber and having a gas outlet opening for the gas bubbles, wherein the degassing chamber includes a ring conduit that extends in an arc shape in a vertical plane and connects the inlet conduit to the outlet conduit in a flow direction and the collecting chamber is positioned in a vertically upper region of the ring conduit. A corresponding method for separating gas bubbles from a liquid flow is also disclosed.

A system includes a gas plant having an inlet slug catcher, downstream processing equipment fluidly connected to the inlet slug catcher, and a downstream flare system fluidly connected to the inlet slug catcher. The system also includes an upstream plant connected to the inlet slug catcher via a transmission pipeline. The upstream plant includes an upstream flare system fluidly connected to the transmission pipeline, wherein the inlet slug catcher has a design pressure equal to or greater than the transmission pipeline design pressure.

A gas compressor comprising a substantially hollow cylindrical drum secured to a fixed shaft and configured to rotate a volume of fluid about a central axis. A plurality of eductors may be affixed to the shaft through support rods and positioned within an interior of the drum to receive a flow of fluid during rotation of the drum. A gas inlet along the fixed shaft comprises a channel through which gas external to the drum may be drawn into the eductors and compressed. Compressed gas accumulates within a central area of the drum and may be harvested through a gas outlet along the fixed shaft. Additional embodiments may comprise pitot tubes to manage a fluid level within the drum, and a cooling system to manage fluid temperature.

An assembly is provided for a turbine engine. This assembly includes a static structure and an impeller rotor housed within the static structure. The impeller rotor includes a vane structure and a shroud. The vane structure includes a first sidewall, a second sidewall and a plurality of vanes arranged circumferentially about a rotational axis. The vanes include a first vane. The first vane includes a first portion, a second portion and a third portion. The first portion is axially between the first sidewall and the second sidewall. The second portion is radially between the first sidewall and the shroud. The third portion is radially between the second sidewall and the shroud. The shroud circumscribes the vane structure. A gap is formed by and extends between the shroud and the static structure. A dimension of the gap changes as the gap extends along the shroud.
