Definitions
- the present invention relates to a pumping system for a cryogenic fluid.
- the invention finds a particularly advantageous application in the field of pumping sparse cryogenic fluids, such as hydrogen and helium, as well as their isotopes.
- sparse cryogenic fluids such as hydrogen and helium
- the generation of hydrogen under high pressure remains extremely expensive in terms of compression energy. Losses by evaporation of liquid hydrogen in a cryogenic pump can also be significant in the event that the pump is not used optimally. The reduction of these losses is an essential point to optimize the costs of obtaining hydrogen under high pressure.
- cryogenic pumps in general and liquid hydrogen pumps in particular, lies in the fact that cryogenic fluids are very sparse, 70 g / 1 to 1 bar for hydrogen for example.
- This very low density has the consequence of causing a certain number of drawbacks: - on the one hand, it is impossible to provide the cryogenic pump with the required input pressure drop compensation (called NPSH for "Net Positive Suction Head ”) by a simple physical installation of the cryogenic source tank loaded on the pumping system.
- NPSH input pressure drop compensation
- an LH2 700 bar liquid hydrogen pump has an NPSH of around 250 mbar, which corresponds to a height of liquid hydrogen of 35 m.
- saturated liquid hydrogen at low pressure is denser than saturated liquid hydrogen at high pressure.
- the density of saturated hydrogen is, as we have seen, from 70 g / l to 1 bar, but it is not
- cryogenic pumps are positive displacement pumps, we conclude that in order to increase the quantities of cryogenic fluid pumped there is interest to make the fluid as dense as possible, therefore to suck it by the pump at a pressure the as low as possible.
- Document EP-A-010464 in the name of the Applicant, describes means for monitoring the starting sequence of pumping relatively dense cryogenic fluid (liquid nitrogen).
- a technical problem to be solved by the object of the present invention is to propose a system for pumping a cryogenic fluid, comprising a reservoir of cryogenic fluid, a cryogenic pump having an input pressure drop and a line d suction connecting said reservoir to said pump, which would remedy the drawbacks related to the low density of cryogenic fluids in terms of compensation for the pressure drop of cryogenic pumps input and quantities of cryogenic fluid sucked.
- the solution to the technical problem posed consists, according to the present invention, in that said pumping system comprises pressure control means capable of maintaining the pressure in the suction line at most equal to the increased saturation pressure of the cryogenic fluid. of the cryogenic pump inlet pressure drop.
- said pressure control means comprise a pressurization valve and a depressurization valve of the cryogenic fluid reservoir. More specifically, the invention provides that said control means comprise a pressure sensor and a fluid temperature sensor
- control means comprise a calculation block capable of calculating from the temperature measured by said temperature sensor a minimum value of the pressure measured by said pressure sensor equal to the saturation pressure of the liquid at said temperature increased by the pressure drop at the inlet of the pump.
- FIG. 1 is a diagram of a pumping system for a cryogenic fluid according to the invention.
- FIG. 1 shows a pumping system for a cryogenic fluid, essentially comprising two cryogenic tanks 8a,
- each reservoir 8a, 8b being connected to said pump 18 by a line
- the cryogenic pump 18 is in operation, the discharge pressure 19 being controlled by a valve 21 for regulating the high pressure fluid located after an exchanger 20 capable of vaporizing high pressure fluid.
- the suction pressure of the pump measured by a pressure sensor 14 is controlled by control means so that the temperature measured in line 23a by a temperature sensor 16 is lower than the saturation temperature of the cryogenic liquid. corresponding to this pressure.
- the control means comprise a block 17 for calculating the minimum value of the pressure 14 on the suction line 23a such that this pressure is equal to the saturation pressure of the liquid at temperature 16 increased by the loss of input load NPSH of the pump 18.
- a control block 15 controls the opening or closing of a valve 12a pressurization or a valve 7a for depressurizing the tank 8a, the selector 13 being in position "A" since the tank 8a being pumped is at this time the tank 8a.
- the pressurization of the reservoir 8a, as well as that of the reservoir 8b, is carried out by means of a source 22 of gas under pressure.
- the pressurization gas from the source 22 of pressurized gas is part of the fluid pressurized by the pump 18.
- the pump 18 is effectively protected against cavitation and that at the same time the pumped fluid is as dense as possible, in accordance with the aim sought by the invention.
- the second reservoir 8b is filled with liquid fluid saturated with its vapor.
- the low level detector 9a becomes active and the system closes the valve 4b then opens the purge valves 10b and 11b bypass return from the reservoir 8b.
- the valves 10a and 11a are closed and the tank 8a is filled via the filling valve 4a, while the pumping and pressure control sequence of the tank 8b begins. This produces continuous production of cryogenic fluid under pressure.
