Definitions
- the present invention relates to a device and a method for pumping a cryogenic fluid.
- the invention relates more particularly to a device for pumping a cryogenic fluid, comprising a storage tank for a cryogenic fluid containing cryogenic liquid, a cryogenic pump having a loss (NPSH) of input charge, a line of suction connecting the reservoir to the pump, the pumping device comprising a system for controlling the pressure in the reservoir to selectively maintain the pressure in the reservoir at least equal to the saturation pressure of the stored cryogenic fluid increased by the loss (NPSH) input load of the cryogenic pump and possibly also increased the value of the pressure drops due to the piping of the suction line connecting the tank to the pump.
- the invention finds a particularly advantageous application in the field of pumping low-density cryogenic fluids comprising gases such as hydrogen or helium, as well as their isotopes.
- a liquid hydrogen pump (LH2) at 700 bar has a pressure drop "NPSH" of about 250 mbar, which corresponds to a liquid hydrogen height of 35 m. It is impossible to operate the pump with a source tank installed on the pump at a height of 35m (even if it was industrially possible, the pressure losses in lines would compensate for the installation in charge of the tank). A solution is therefore to "cool" the liquid and suck this liquid under cooling. Subcooling is the process of increasing the pressure of a saturated fluid, or of reducing its temperature, at constant pressure, without waiting for the establishment of a new liquid-vapor equilibrium.
- Hydrogen under pressure is however less dense than hydrogen at atmospheric pressure.
- the density of saturated hydrogen at 1 bar absolute is 70 g / l while it is 56g / l at 7 bar absolute. Since liquid hydrogen pumps are volumetric systems, it is therefore interesting to suck up the densest possible hydrogen, thus saturated at the lowest possible pressure (the coldest), in order to optimize the quantities pumped.
- the invention described below makes it possible in particular to use a plant for pumping liquid hydrogen continuously from a source of hydrogen in liquid-gas equilibrium at a low pressure (between 1 and 12 bar) and optimize the operation of such an installation by allowing continuous operation of the pump while maximizing the density of the pumped hydrogen, thus maximizing the pumped flow rate.
- the tank is pressurized via a thermosyphon (atmospheric pressure warmer), or directly by high pressure hydrogen in bottles at room temperature.
- An object of the present invention is to overcome all or part of the disadvantages of the prior art noted above.
- the device according to the invention is essentially characterized in that the pressure control system comprises at least one of: pipe connecting a high pressure outlet of the pump to the reservoir for selectively injecting pumped cold fluid into the reservoir, a pipe connecting a source of high pressure gas to the reservoir via a gas cooling member, for selectively injecting cooled gas into the reservoir .
- the invention also relates to a method of pumping a cryogenic fluid from a cryogenic fluid reservoir comprising cryogenic liquid, the fluid being pumped via a suction line comprising a cryogenic pump having an inlet pressure drop, the method comprising a step of controlling the pressure in the reservoir to selectively maintain the pressure in the reservoir and / or in the suction line at least equal to the saturation pressure of the cryogenic fluid increased by the inlet pressure drop of the cryogenic pump and possibly also increased the value of the pressure drops due to the piping of the suction line connecting the tank to the pump.
- the method is characterized in that the step of controlling the pressure in the tank comprises introducing said cold gas into the tank at a temperature below room temperature outside the tank and preferably between between 40 ° K and 100 ° K and at a pressure between 1 and 12 bar.
- the invention may also relate to any alternative device or method comprising any combination of the above or below features.
- the device comprises a reservoir 1 of cryogenic fluid (vacuum insulated) containing a liquid-gas mixture, for example at the temperature and a pressure of between 1 and 12 bar abs.
- cryogenic fluid vacuum insulated
- the temperature and the pressure in the tank 1 are measured by corresponding sensors 101, 10.
- the lower part of the tank 1 is connected to the suction inlet of a cryogenic pump 3 by a suction line 2 vacuum insulated and comprising one or more isolation valves.
- the pump 3 comprises a gas evacuation line 4 (produced for example by heating / friction) towards the upper part of the tank 1 and provided with valves.
- the pump is connected to a high pressure discharge line 5 generally incorporating a discharge valve (high pressure outlet of the pumped fluid).
- the high-pressure discharge line 5 is connected to a cold hydrogen feed line 6 of a preferably high-inertia exchanger 10.
- the fluid passes through a cold high-pressure line 11 and then through a high-pressure atmospheric heater (or equivalent) 12 to a gas supply line 111 having an end connectable to a user U (tank or bottle for example) via a pressure regulator 13.
- the thermally isolated high-pressure discharge line 5 is also connected to the upper part of the tank 1 via a pipe 9 for pressurizing the tank 1 by cooled hydrogen coming from the pump 3.
- the pipe 9 for pressurizing the tank 1 comprises a pressure reducer 99 and / or a control valve.
- the upper end of the tank 1 is connected to a valve 20 for depressurizing the tank (towards the outside), for example via the pressurization pipe 9.
- the pressurization pipe 9 is also connected to a source 16 of pressurized gas such as bottles 16 at ambient temperature via a line 29 passing through the exchanger 10 with high inertia (with heat exchange) and comprising a control valve 15 ( regulator for example).
- a source 16 of pressurized gas such as bottles 16 at ambient temperature via a line 29 passing through the exchanger 10 with high inertia (with heat exchange) and comprising a control valve 15 ( regulator for example).
- the gas supply line 111 is also connected to the source 6 of high-pressure gas via a pressure reducer 14.
- a block 18 for controlling the pressure of the tank 1 receives the pressure information from the pressure sensor 100 and controls a selector 17 which selectively actuates the pressure reducer / control valve 99 of the pressurization pipe 9 and the valve 15. control of the line 29 connected to the source 16 of gas under pressure.
- a calculation block 19 determines the saturation pressure in the tank 1 as a function of the temperature detected by the valve 101 and controls the control block 19 according to the result.
- the hydrogen at the pressure, and the temperature of the tank 1 is supplied by the tank 1 to the pump 3 via the isolated line 2 under vacuum.
- the hydrogen is pumped by the pump 3 and is discharged at high pressure (between 200 and 850 bar for example) by the discharge line 5 to the exchanger 10 and the line 11 high cold pressure.
- Heater 12 increases the temperature of hydrogen to room temperature.
- the expander 14 ensures that the reservoirs 16 are at a maximum pressure.
- the upstream pressure regulator 13 controls the pressure in the pump.
- the system carries out a control of the pressure of the tank 1.
- the set pressure of the tank 1 is calculated by the calculation block 19 so that the pressure in the tank is equal to the saturation pressure of the hydrogen at the raised temperature (101) added with the loss (NPSH) of the inlet charge of the pump 3 and the pressure drops in the suction pipe 2.
- the value of the pressure drop (NPSH) is given by example by the supplier of the pump 3.
- the device according to the invention has the possibility of using, during the operation of the pump 3, hydrogen coming directly from the cold high pressure outlet 5 of the pump 3 (for example hydrogen at about 70 ° K for 450 bar pressure).
- This hydrogen supplied by the pump 3 can be expanded via the valve 99 of the pressurization pipe 9 and reinjected into the tank 1 in the form of gas and / or cold liquid.
- the device according to the invention furthermore has the possibility of using, before starting the pump 3, high-pressure bottles 16 at ambient temperature to inject cold hydrogen (by passing through the exchanger / accumulator 10) in the tank 1 in order to cool the hydrogen by pressurizing the tank 1.
- the cold accumulator (in the exchanger 10) is for example previously cold set during the operation preceding the pump 3.
- the cold accumulator can be insulated with polyurethane foam or equivalent.
- the tank 1 can be depressurized using the depressurization valve 20 of the tank 1, to cool the hydrogen remaining in the tank 1.
- the hydrogen used for the pressurization of the tank 1 is thus pre-cooled.
- the thermal stratification of the gas in the tank is then lower, its rise in pressure is slower, which increases the pumping time available before reaching the maximum operating pressure of the tank 1.
- the exchanger 10 with high inertia and preferably isolated from the outside makes it possible to have a source of cold which makes it possible to pressurize the tank 1 with cold hydrogen even when the pump 3 is not not in use (from bottles 16 or equivalent).
- Thermal inertia of the exchanger 10 and its isolation mode is determined so that its temperature preferably remains constant (+/- 10 ° C) between two phases of operation of the pump 3.
- the device described allows a greater accuracy and speed of control of the pressure of the tank 1 than in the prior art, especially with respect to a thermosiphon system.
- the figure illustrates a variant that differs from the embodiment of the figure 1 only with respect to line 4 gas evacuation.
- the other elements are designated by the same references and are not described a second time.
- line 4 for evacuation or return of hydrogen is returned to a capacity 21 called degassing.
- the return line 4 communicates with a degassing tank 21 whose level is controlled by valves 23, 24 after having been heated by an atmospheric heater 22. This configuration makes it possible to prevent the hot hydrogen from returning to the atmosphere. the cryogenic tank 1 and warms all the liquid hydrogen contained therein.
- the invention thus makes it possible to obtain an under cooling of the cryogenic fluid and an aspiration of the fluid thus sub-cooled.
- the compensation of the inlet pressure drop is thus achieved, avoiding any cavitation phenomenon in the pump 3 while the fluid is maintained at a pressure sufficiently low to maximize the density of the fluid and therefore the quantity pumped.
- control of the pressurization of the tank 1 according to the invention does not affect or little the level of liquid in the tank and thus pumping time available before reaching the maximum operating pressure of the tank 1.
