Definitions
- the present invention relates generally to a method and system for calculating in real time the run time of a non-refrigerated tank containing natural gas (usually referred to by the acronym GN), comprising a layer of natural gas liquefied natural gas (LNG) and a layer of gaseous natural gas (NGG).
- GN natural gas
- LNG natural gas liquefied natural gas
- NSG gaseous natural gas
- the meaning of the present invention means the retention time (or storage time) remaining natural gas in the tank before opening the valves of the tank.
- Liquefied natural gas (abbreviated as LNG) is typically natural gas composed mainly of condensed methane in the liquid state: When it is cooled to a temperature of about -160 ° C at atmospheric pressure, it takes the form of a clear, transparent, odorless, non-corrosive and non-toxic liquid. In a tank containing LNG, it is generally in the form of a layer of liquid, which is covered by a layer of gas ("gaseous sky").
- LNG fuel is a simple and effective alternative to conventional fuels. From the point of view of CO 2 emission, as well as polluting particles and energy density. More and more players are turning to its use, including road, marine and rail carriers.
- one of the intrinsic defects of LNG is its quality of cryogenic liquid at atmospheric pressure. This means that LNG must be maintained at a temperature well below room temperature to remain in a liquid state. This implies unavoidable heat inputs into the non-refrigerated LNG tank and thus a rise in pressure in the gaseous layer until the valves of the tank are opened. This rise in pressure limits the duration of autonomy of the LNG in the tank.
- the duration of autonomy is a parameter that is crucial to know, in order to size the supply chain, and in particular LNG transport and inform the operator in real time of the remaining period of autonomy (from the same way that the duration of battery life is generally communicated to the user).
- the duration of autonomy is crucial to know, in order to size the supply chain, and in particular LNG transport and inform the operator in real time of the remaining period of autonomy (from the same way that the duration of battery life is generally communicated to the user).
- the Applicant has developed a method and system for real-time calculation of the life span of a non-refrigerated LNG-containing tank, which can provide instantaneously the battery life of a tank.
- LNG tank in operation :
- thermodynamic parameters of the LNG measured inside the tank by sensors inside the tank liquid and gas temperatures and compositions, LNG gas pressure and proportion of liquid LNG in the tank
- the present invention therefore relates to a method for calculating in real time the autonomy time of a non-refrigerated tank and defined by a calibration pressure p S0U p p, its shape and dimensions, and its rate of evaporation, (usually referred to in English as "Boil Off Rate” and the corresponding acronym BOR (input data relating to the tank), said tank containing natural gas (GN) being divided into:
- a layer of natural gas in the liquid state defined at a time t given by its temperature Tii q (t), its composition xn q (t), and the filling rate of the tank by said layer of natural gas in the liquid state (thermodynamic parameters relating to the GN in the 1-liquid state);
- a layer of natural gas in the gaseous state defined at a given instant t by its temperature T gas (t) and its composition x gas (t), and a pressure p (t) (thermodynamic parameters relating to GN in the gaseous state);
- the physical parameters of said layers of liquefied natural gas are initialized, by measurement with the aid of pressure and temperature sensors, the pressure of the gas p (to), and the temperature Ti ( qo ), while the respective compositions of the liquid xii q (to) and gaseous x gas (to) phases are known input data corresponding to the respective compositions of the liquid and gaseous at the time of loading of the tank, or at average compositions for the type of LNG used;
- step B is repeated for the instant following t + ⁇ t, with a physical step time constant (in particular of the order d one minute, depending on heat flux, and time constants thermodynamic equilibria).
- the duration of autonomy sought is equal to the total duration N * ôt traveled by the algorithm at the time of stopping the calculation.
- the tank can operate in open system (transported in this case by a running vehicle) or closed (transported in this case by a stopped vehicle) or not transported).
- the input data relating to the tank can be in different forms, for example prismatic, cylindrical, or spherical. Its dimensions can typically be of the order of 1.5 m in length and 0.5 m in diameter for a cylindrical vessel.
- the calibration pressure of the valves of the tank p S oup is given by the manufacturer of the LNG tank. It is typically of the order of 16 bars for a tank of 300 liters of volume and can even go up to 25 bars.
- evaporation rate means, within the meaning of the present application, the equivalent volume of liquid that would be evaporated per day because of the heat inputs in the case where the tank would be open . It is also a specific value of the tank, usually given by the manufacturer.
- thermodynamic parameters relating to the GN it is assumed that the liquefied natural gas contained in the tank is divided into a layer of natural gas in the liquid state and a layer of natural gas in the gaseous state. , as illustrated in FIG. 1.
- Each layer is defined at each instant t by its temperature T iiq (t) and T gas (t) (respectively for the layer of LNG in the liquid state and the layer of LNG at the gaseous state) and its composition xn q (t) and x gas (t) (respectively for the LNG layer and the GNG layer).
- the gaseous phase i.e., the natural gas layer in the gaseous state
- p (t) which is calculated at each moment t by the state equation of Peng-Robinson [1]
- the liquid phase ie the layer of natural gas in the liquid state
- the filling rate z of the tank by the layer of natural gas in the liquid state is typically of the order of 80 to 90% by volume after loading the tank and at the end of range, of the order of 10 to 20 % in volume.
- compositions xii q (t) and x gas (t) are vectors giving the mass fraction of each component of the LNG (usually the mass fraction of CH 4 , C 2 H 6 , C 3 H 8 , 1 C 4 H 10 , nC 4 H 10 , 1 C 5 H 12 , nC 5 Hi2, ⁇ 4 and N 2 in each of the gaseous or liquid phases of the LNG).
- the liquid phase and the gas phase are not necessarily in thermodynamic equilibrium: in fact the compression of the gas phase during a filling can induce a delay in the heat exchanges between the two phases (liquid at over-cooled state).
- the calculation method according to the invention consists of an algorithm (or code of behavior of the GN) comprising different steps A to D.
- This code (or algorithm) takes into account several physical phenomena (detailed below), which impact the pressure :
- the behavior code of the GN is of iterative type, that is to say that it calculates the evolution of the pressure at each physical time step until the opening of the valves.
- the first (step A) consists in initializing, at an initial time to, the physical parameters of said layers of liquefied natural gas, by measurement (continuously) using pressure and temperature sensors, the pressure of the gas p (to), and the temperature of the liquid Tiiq (to).
- the respective compositions of the liquid xii q (to) and gaseous x gas (to) phases are known input data corresponding to the respective compositions of the liquid and gaseous phases at the time of loading of the tank, or to compositions averages for the type of LNG used.
- step B the physical parameters p (t), T gas (t), and Ti iq (t) are calculated using equations based on the conservation of the mass and the energy of the liquid and gaseous natural gas contained in the tank.
