Embodiment Construction

[0086] As previously mentioned, the temperature and pressure in the liquefied gas (LNG) storage can be specifically controlled to control the generation of NBOG in the storage.

[0087] Liquefied gas storage units, especially those used in liquefied gas carriers, typically include:

[0088] - at least one liquefied gas storage tank,

[0089] - means for pumping liquid and / or gaseous gases in the reservoir, and

[0090] - means for injecting the gas in liquid form into the reservoir, the means being connected to the gas extraction means.

[0091] As part of the first objective above, the overhead gas is cooled using subcooled LNG spray bars. LNG is withdrawn by extraction means, subcooled by subcooling means, and then injected by a rod (injection means) at the top of the reservoir. By maximizing the exchange surface between the liquid droplets and the gas to allow them to condense, the shower makes it possible to directly affect the temperature and pressure of the gas above....

Abstract

Liquefied gas storage device, in particular for a liquefied gas carrier or for a land-based facility, comprising: - at least one liquefied gas storage tank (12) that has a tank bottom and a tank ceiling which together define a tank height, - means (20) for drawing off gas, in liquid and / or gaseous form, in said tank, and - means (10) for injecting gas in liquid form into said tank, which means are connected to the gas draw-off means, characterized in that the gas injection means comprise at least one injector-mixer (10) which is located in a lower zone of the tank extending between 0 and 25% of the tank height measured from the tank bottom, and / or in an upper zone of the tank extending between 75% and 100% of the tank height measured from the tank bottom, and which is intended to be immersed in said liquefied gas contained in the tank.

Description

technical field [0001] In particular the invention relates to a liquefied gas storage device, in particular for a liquefied gas carrier or for a land-based installation. Background technique [0002] To transport gas, such as natural gas, over long distances more easily, the gas is usually liquefied (turned into liquefied natural gas - LNG) by cooling it to cryogenic temperatures, for example to 160°C at atmospheric pressure. The liquefied gas is then loaded into vehicles, such as LNG vehicles and bunkering vessels. [0003] In order to limit the evaporation of the liquefied gas contained in the tank of the ship, it is known practice to store it in this tank under pressure so as to move on the vaporization curve of the liquefied gas under consideration, thereby increasing its gasification temperature. Liquefied gases can thus be stored at higher temperatures, which leads to limited evaporation of the gas. [0004] However, natural evaporation of gas is inevitable. This ph...
