Definitions
- the invention relates to a liquefied gas storage tank.
- the invention relates more particularly to a liquefied gas storage tank comprising a sealed envelope delimiting a storage volume for the liquefied gas, the envelope comprising a lower end and an upper end, the tank comprising a device for measuring the liquid level. in the casing, the device for measuring the liquid level comprising, arranged in the casing, a float and a guide for moving the float.
- An aim of the present invention is to overcome all or part of the drawbacks of the prior art noted above.
- the reservoir according to the invention is essentially characterized in that the guide comprises an end connected to an upper part of the casing and a lower end connected to a lower part of the casing, the float being mounted movable in translation on the guide so that the float is free to slide along the guide, the device for measuring the liquid level further comprising at least one float position sensor.
- embodiments of the invention may include one or more of the following characteristics:
- the guide includes a rigid axis
- the guide is oriented in the vertical direction in one envelope
- the at least one position sensor is an optical or laser detection sensor configured to detect the position or the distance of the float with respect to a reference
- the at least one position sensor is located outside the enclosure, at the upper end and / or the lower end of the enclosure
- the at least one position sensor is located plumb and / or at the base of the guide
- the tank comprises an outer wall arranged around the casing with an intermediate space containing thermal insulation
- the at least one position sensor is fixed outside the volume delimited by the outer wall, in particular on the outer surface of the outer wall, that is to say outside the intermediate space containing the insulation thermal,
- the envelope includes at least one window located between the sensor and the float, the window being configured to allow the passage of a detection signal from the sensor such as an optical or laser signal,
- the liquid level measuring device comprises a tank inclination sensor and an electronic data storage and processing device configured to correct the level measurement made by the at least one position sensor as a function of the measurement of tilt sensor, that is to say to increase or reduce the liquid level value given by the position of the float according to the tilt angle measured by the tilt sensor.
- 1 / invention may also relate to any alternative device or method comprising any combination of the characteristics above or below.
- FIG. 1 which shows a sectional view, schematic and partial, illustrating an example of the structure and possible operation of a tank according to the invention.
- the liquefied gas storage tank 1 illustrated in [Fig. 1] is a cylindrical double-walled tank comprising a sealed internal casing 2 delimiting the storage volume for the liquefied gas and surrounded by an outer wall 3 arranged around the casing 2 with an intermediate space containing thermal insulation (vacuum and / or layer (s) of thermal insulation).
- thermal insulation vacuum and / or layer (s) of thermal insulation.
- the invention can be applied to any other type of tank (structure and shape).
- the casing 2 comprising a lower end and an upper end.
- the reservoir 1 and in particular the casing 2 comprises a device for window (s) 8 sealed against vacuum allowing the optical passage of a signal from at least one level probe 6 placed outside the casing. 2, in particular on the outside of the outer wall 3.
- This device for measuring the liquid level comprises, arranged in the casing 2, a float 4 and a guide 5 for the movement of the float 4.
- the guide 5 comprises an end connected (fixed) to an upper part of the casing 2 and a lower end connected (fixed) to a lower part of the casing 2.
- the guide 5 is in a fixed vertical position or slightly inclined from the vertical.
- the float 4 is mounted to move in translation on the guide 5 so that the float 4 is free to slide along the guide 5.
- the device for measuring the liquid level therefore further comprises at least one sensor 6 for the position of the float 4. In the example illustrated in [Fig. 1], two sensors 6 are shown and located respectively in the upper and lower part of the outer wall 3 (on the outer surface of the latter).
- a second lower sensor 6 can in particular be placed in opposition to the other upper sensor in order to improve the precision of the measurement and to ensure redundancy for example (or vice versa).
- the float 4 which may conform to known floats, is configured to be compatible with the type of fluid and the level of temperature and pressure present in the casing 2.
- the float 4 is sized so as to have a lower density than the cryogenic fluid (and a higher density than the gas).
- a detectable structure can be associated (assembled) with a floating structure.
- the float comprises a metallic sphere filled with gas under pressure (or under vacuum) and ensuring the float of the float.
- the float 4 is preferably placed in the casing 2 such that it is subjected only to a lesser extent to the movements of the free surface of the liquid. This could be optimized, for example, depending on the geometry of the tank 1.
- the float 4 is guided on a guide which can be a rigid axis such as a rail or a wire rope for example.
- This float 4 (or several floats if necessary) is coupled to at least one level sensor 6.
- This sensor 6 or these sensors will preferably use laser technology or any other suitable technology having sufficient range.
- the sensor (s) 6 can be placed on the outer face of the upper wall of the outer wall 3, that is to say outside the volume which contains the insulation. The sensor 6 will then detect the float 4 through sealed windows 8.
- These windows 8 can consist of a local modification of the nature of the material of the sealed casing 2.
- a window 8 made of sapphire (or equivalent material), which does not allow infrared radiation to pass, is inserted in a sealed manner into an opening in the wall 2.
- the window 8 is mounted on a fixed flange. in the wall 2.
- the senor (s) 6 are not arranged in the inter-wall space 2, 3.
- Another suitable sensor technology 6 can be used (ultrasound, induction).
- the float 4 can be equipped with a flat surface or the like which is perpendicular to the axis of propagation of the measurement waves of the sensor (s) 6.
- the float 4 is guided in translation along the guide axis 5 which coincides with the main direction of propagation of the measurement or of detection of the sensor (s).
- the measurement processing of the sensor (s) 6 can be coupled to a tilt detector 7 of the tank 1 in order to correct the height measurement (and therefore of the quantity) of liquid in the tank.
- the measurement processing of the sensor (s) 6, 7 can advantageously be averaged so as not to take account of the noise due for example to the movement of the free surface of the liquid. This simple and inexpensive solution allows efficient measurement of the liquid height.
