The invention relates to a fluid flow device comprising a plurality of fluid flow functional modules each fastened on a respective individual base comprising: two parallel lateral faces via which the bases are adapted to be placed against one another in such a manner that when the bases are placed against one another, two of the bases each have one lateral face that is free; a primary fluid transport channel passing through the base to open out in its two lateral faces in identical positions; and a front face along which the module extends so as to couple an inlet channel of said module with a secondary channel extending in the base from the front face and opening out in the primary channel.

According to the invention, the device includes fastener means for fastening the bases to one another and leaktight coupling means for coupling the end of the primary channel opening out in one of the lateral faces to a source of fluid under pressure for feeding the modules.

A gas-oil separation plant (GOSP) is configured to process crude oil produced from a well. A production stream from the well operates at a first pressure. A processed crude oil stream from the GOSP flows to a multi-phase ejector. The multi-phase ejector induces flow of a production stream from the well in response to the flow of the processed crude oil stream.

A refrigerant that has flowed out of a liquid ejector radiates heat in a radiator, and a liquid-phase refrigerant that has radiated heat in the radiator flows into an ejection refrigerant passage of the liquid ejector. A discharged refrigerant of a compressor that suctions the refrigerant that has flowed out of a low-pressure evaporator flows into an inflow refrigerant passage of the liquid ejector. An ejector adopted as the liquid ejector is one in which an ejection refrigerant is ejected from the ejection refrigerant passage to a gas-liquid mixing portion, and the ejection refrigerant is ejected on an outer circumferential side of the inflow refrigerant flowing from the inflow refrigerant passage into the gas-liquid mixing portion.

A hydrogen fuel system for an aircraft is configured to provide hydrogen fuel to the engines for propulsion. The fuel system also may provide hydrogen fuel to a fuel cell arrangement to generate electricity for use on the aircraft. The fuel cell arrangement may be selectively coupled to the feed lines for the engines. A ventilation system regulates the pressure within the one or more fuel tanks and the feed lines. The ventilation system can vent hydrogen vapor to atmosphere or can transfer hydrogen vapor between the fuel tanks and the fuel cell arrangement. A jet pump and accumulator may pull vapor from the feed lines as needed.
