Embodiment Construction
[0197] figure 1 A first embodiment of a device 10 according to the invention is shown. The device 10 may be considered to enable cooling of liquefied gas and / or cooling of natural vaporization of liquefied gas.
[0198] The device 10 is particularly (but not exclusively) suitable for supplying combustible gases to ships, such as liquefied gas transport ships. The device 10 can thus be used for supplying a power generation plant 12 , in particular a power generation plant on a ship, with combustible gas.
[0199] The vessel comprises a tank 14 or tanks 14 for storing liquefied gas. The gas is, for example, methane or a gas mixture comprising methane. The or each tank 14 may contain a gas that liquefies at a predetermined pressure and temperature, for example, atmospheric pressure and a temperature of about -160 degrees Celsius. One or more tanks 14 of the vessel may be connected to the equipment 12 via the device 10 of the present invention. Therefore, the number of cabine...

A device (10) for cooling liquefied gas for a power generation facility (12), in particular a power generation facility (12) on a ship, characterized in that the device comprises: optionally, a main storage tank (14) for storing liquefied gas (14a), a first tank (24) for separating cooled liquefied gas (24a), a depressurizing device (26) for depressurizing the first tank with respect to a main case, a vaporization device ( 18, 19) equipped with the inlet of a first guide pipe and / or the first tank, and a supply device (22, 30, 32, 34, 40) for supplying the cooled liquefied gas to the main caseso as to cool gas in the main case.
Description
technical field [0001] The invention relates to a device and method for cooling liquefied gas and / or natural gasification of liquefied gas. The device and the method are used in energy generating plants, in particular on ships, such as ships transporting liquefied gases or machines using liquefied gases on ships. Background technique [0002] In particular, the prior art includes the following documents: WO-A1-2012 / 089891, FR-A1-2920484, WO-A1-2005 / 058684 and WO-A-2016 / 075399. [0003] To facilitate the long-distance transportation of gases such as natural gas, the gas is usually liquefied (to become liquefied natural gas GNL) by cooling the gas to a low temperature (eg, -163 degrees Celsius) at atmospheric pressure. The liquefied gas is then loaded into dedicated vessels. [0004] In ships transporting liquefied gases, such as natural gas carriers, it is contemplated that there are energy generating devices to be able to meet the energy requirements for the operation of t...
