The invention relates to an apparatus for separating fluid mixtures, being equipped with a nozzle for feeding a fluid mixture composed of a number of components of different density into a volume. The nozzle has a conical annular gap located between a conical inner face of a nozzle casing and a guide cone and opening out at its tip at a nozzle opening into the volume, and a fluid feed leading tangentially into the conical annular gap. Furthermore, the apparatus has a separator, which has a separation portion located in the volume and fluidically connected to a discharge line, and has an inlet opening arranged concentrically to the nozzle opening and axially spaced therefrom. The apparatus according to the invention enables an efficient and trouble-free separation of fluid mixtures, in particular the separation of dissolved gases from a liquid or suspension.

A device for the contact of a gas phase with a liquid medium, and a method for operating the device. The liquid medium here is directed into the device and some of it is raised by means of a conveying device. The liquid medium raised is distributed over a rotating brush by way of a distributing means. At least one gas inlet and a fan here generate a gas stream from a lower portion of the device to an upper portion of the device. The liquid medium distributed over the upper surface of the brush is directed back by way of the brush, counter to the gas stream, into the lower region.

The described air-oil separation apparatus for an oil system of a gas turbine engine includes an oil tank having an oil impingement surface disposed on a tank bottom proximate an oil tank outlet and a centrifugal air-oil separator mounted within the oil tank. The centrifugal air-oil separator has an oil outlet that feeds an impingement nozzle having an outlet oriented, in operation, to eject an oil jet from the centrifugal air-oil separator to impinge the oil impingement surface at an intersection point spaced apart from the oil tank outlet.

A drink producing apparatus includes a dispensing unit for dispensing liquid from the drink producing apparatus, a dispensing container, which is formed for receiving a liquid addable to a drink by the drink producing apparatus in a first liquid state, a carbon dioxide addition unit for adding carbon dioxide into the dispensing container upon dispensing liquid from the dispensing container, a decarbonization device, by which the liquid remaining in the dispensing container and carbonized with the introduced carbon dioxide is decarbonized. The invention also relates to a household refrigeration apparatus and to a method.

A gas trap system for releasing gas-phase fluids is provided herein. The gas trap system is designed to reside within a return fluids tank, such as at a drill site. The gas trap system first includes a gas trap. The gas trap is configured to agitate drilling fluids in the return tank, and then to release gases during agitation. Liquids are circulated and released through a liquids exhaust port while gases are released through a gas exhaust port near the top of the gas trap. The gas trap system is configured to float along vertical guide rods in response to changes in height, weight and viscosity of the drilling fluids in the return tank. A method of capturing gaseous phase fluids from a fluid return is also provided herein. The fluid return is preferably drilling fluids at a drill site.

A centrifugal separator for separating gas and liquid from a gas-liquid mixture, the centrifugal separator comprising: a housing having a cavity and a gas-liquid mixture inlet leading tangentially into the cavity along an inlet path to form a vortex therein, a separated gas outlet and a separated liquid outlet; and a rotor rotatably mounted to the housing inside the cavity in a manner to be freely rotatable around a rotation axis, the rotor having a hub extending axially along said axis, the rotor having a plurality of vanes extending radially from the hub inside the cavity, the vanes being disposed in the inlet path in a manner so that the rotor is rotated by the gas-liquid mixture during use.

The present invention concerns a gas-liquid separation system and a method for operating a gas-liquid separation system.
