Definitions
- the invention relates to the field of tanks, sealed and thermally insulating for the storage and / or transport of a liquefied gas, such as tanks for the transport of Liquefied Petroleum Gas (also called LPG) having for example a temperature between -50 ° C and 0 ° C, or for the transport of Liquefied Natural Gas (LNG) at approximately -162 ° C at atmospheric pressure.
- LPG Liquefied Petroleum Gas
- LNG Liquefied Natural Gas
- tanks can be installed on land or on a floating structure.
- the tank may be intended for the transport of liquefied gas or to receive liquefied gas serving as fuel for the propulsion of the floating structure.
- Document WO2013093261 discloses a sealed and thermally insulating tank for the storage of a liquefied gas in a state of liquid-vapor equilibrium. Due to the phenomena of heat transfer between the inside and the outside of the tank, the liquefied gas stored in the tank absorbs heat, which causes it to evaporate. Also, the vessel is equipped with a collecting pipe which passes through a wall of the vessel and which is intended to extract steam from the gas overhead of the vessel. The collecting pipe opens into the internal space of the tank to define a passage between the internal space of the tank and a vapor collector which is arranged outside the tank and which is connected for example to a degassing mast. .
- the collecting pipe is connected to the vapor manifold via a safety valve which is calibrated in order to ensure evacuation of the gas in the vapor phase of the vessel, when the vapor pressure in the gas overhead of the vessel is greater than a threshold pressure. This allows the pressure inside the tank to be controlled so as to avoid overpressures that could damage the tank.
- the walls of the sealed tank have a multilayer structure, that is to say comprise successively, from the outside to the inside of the tank, a secondary thermally insulating barrier, a secondary waterproof membrane, a thermally barrier primary insulation and a primary waterproof membrane.
- a secondary thermally insulating barrier In order to ensure the continuity of the primary waterproof membrane around the collecting pipe, the latter is connected in a sealed manner to the primary waterproof membrane by means of a collar which has an L-shaped section and which protrudes. inside space inside the tank. The lower end of the collecting pipe therefore protrudes into the internal space of the tank, beyond the sealed primary membrane.
- An idea at the basis of the invention is to provide a tank equipped with a collecting pipe intended to collect steam in the gas overhead of the tank and passing through a ceiling wall of the tank and which allows load an optimum quantity of liquefied gas while allowing the vapor to be extracted from the gas overhead via said collecting pipe and, whatever the vertical dimension of the portion of said collecting vapor pipe projecting inside the internal space of the tank.
- the invention provides a sealed and thermally insulating tank for the storage of a liquefied gas, said tank comprising:
- a plurality of walls defining an internal space intended for the storage of liquefied gas, the plurality of walls comprising an upper wall;
- a collecting pipe intended to extract, from the internal space of the vessel, liquefied gas in the vapor phase, said collecting pipe passing through the upper wall, and comprising a lower end which opens into the internal space and which projects towards the low, beyond the upper wall, to a height h;
- first pipe intended to conduct liquefied gas in vapor phase from the internal space of the vessel to the collecting pipe, said first pipe comprising a first and a second end, the first end being located in the internal space of the tank, outside the collecting pipe, and opening into said internal space at a height h1 greater than h, the second end opening inside the collecting pipe at a height h2 greater than h, the first pipe comprising a diverted section that passes below the lower end of the header pipe to connect the first and second ends of the first pipe.
- the first pipe provides fluid communication between the gas overhead and the interior space of the header pipe even if the lower end of the header pipe is immersed in the liquid phase of the liquefied gas.
- such a tank may include one or more of the following characteristics.
- the diverted section has a U-shape.
- the height h is less than a maximum loading level hmax.
- the height h1 is greater than the maximum loading level hmax.
- the height h2 is greater than the maximum loading level hmax.
- the header pipe is connected to a safety valve which is configured to extract liquefied gas in the vapor phase from the header pipe when the pressure in the interior space of the header pipe is greater than a threshold pressure Ps.
- the threshold pressure Ps satisfies the following inequality:
- the threshold pressure Ps satisfies the following inequality:
- P design the maximum design pressure for which the tank was dimensioned
- f the density of the liquefied gas intended to be stored in the tank
- g the normal acceleration of gravity
- h2 the height of the second end of the first pipe
- h3 a height of the lowest point of the first pipe.
- the threshold pressure Ps further satisfies the following inequality: Ps> Pdesign - f * g * (h2 - h3) - k; with k between 100 and 1000 Pa.
- the threshold pressure Ps satisfies the following inequality: Ps ⁇ Pdesign - f * g * I; with:
- P design the maximum design pressure for which the tank was dimensioned
- f the density of the liquefied gas intended to be stored in the tank
- g the normal acceleration of gravity
- I a length of the first pipe which is likely to be filled with liquefied gas, when the tank is charged with liquefied gas up to a maximum loading level hmax.
- the threshold pressure Ps further satisfies the following inequality:
- the upper wall comprises a sealed primary membrane intended to be in contact with the liquefied gas stored in the tank, the sealed primary membrane having corrugations projecting towards the inside of the tank and the pipe. collector protrudes inside the internal space, beyond the corrugations of the waterproof primary membrane.
- the collecting pipe projects inside the internal space, beyond the upper wall, by a vertical distance greater than 80 mm, preferably greater than 100 mm, by example of the order of 150 mm.
- the tank comprises one or more lines for loading and / or unloading the tank which pass inside the collecting pipe.
- the collecting pipe forms both a gas dome structure and a liquid dome structure, which makes it possible to simplify the construction of the vessel and to reduce its cost.
