Definitions
- 1 / invention relates to an apparatus for compressing cryogenic fluid as well as to a filling station comprising such an apparatus.
- the invention relates more particularly to a fluid compression apparatus with several compression stages comprising a first compression chamber, a second compression chamber, an intake system communicating with the first compression chamber configured to allow the entry of fluid. to compress in said first compression chamber, a transfer system configured to allow in the open position the transfer of fluid from the first compression chamber to the second compression chamber, a movable piston to ensure the compression of the fluid in the first and second compression chambers, the apparatus further comprising an evacuation orifice communicating with the second compression chamber and configured to allow the outlet of compressed fluid, the piston being movable in translation in a longitudinal direction, the first compression chamber being delimited by a fixed lower cavity, a lower end of the piston and a first sealing system formed between the piston and a wall of the lower cavity, the second compression chamber being delimited by a fixed upper cavity, an upper end of the piston and a second sealing system formed between the piston and a wall of the upper cavity.
- the invention relates in particular to an apparatus for compressing or pumping cryogenic gases and / or liquids.
- compression device in fact relates to a pumping and / or pumping apparatus. compression of liquid and / or gaseous and / or supercritical cryogenic fluid.
- cryogenic fluids have much higher densities than gaseous fluids. Therefore, cryogenic pumps (as opposed to gas compressors) offer higher mass flow rates, smaller volume consume less energy and require less maintenance. This is why cryogenic pumps are used in many fields such as air separation units, reformers, filling stations, maritime sectors.
- the fluids involved generally include oxygen, nitrogen, natural gas, argon, helium or hydrogen.
- the function of these compression devices (or pumps) is to pressurize a cryogenic fluid to a target flow rate.
- a cryogenic piston pump can be placed directly in line at the outlet of the cryogenic source storage or even in a dedicated cryogenic bath (also called "sump" in English), located next to and directly fed by a main storage tank .
- cryogenic pump is reciprocating and is inserted into a reservoir so as to be submerged in the cryogenic fluid to be pumped.
- Cryogenic pumps typically have inlet pressures of 1 to 12 bar and outlet pressures of 20 to 1000 bar, depending on the application. Pumps can have one or more stages of compression using a reciprocating motion.
- a two-stage compression mechanism is often preferred because this allows to decouple the intake phase (during which the fluid must be as dense and therefore as cold as possible) and the pressurization phase (where harmful amounts of heat for the process can be generated).
- the main performance indicators of cryogenic piston pumps are: volumetric efficiency, evaporative losses, energy consumption, footprint and durability.
- the main characteristics of reciprocating cryogenic pumps should therefore be: the highest possible suction density, very good thermal insulation with the environment, minimum dead volume (therefore a high compression ratio), simple assembly and robust for rapid maintenance and high reliability, good management of evaporative losses in order to limit their impact.
- Document US7410348 describes a two-stage horizontal piston compression pump with an axial inlet via a non-return valve and a radial discharge. This architecture has a significant dead volume. In addition, the leakage losses are relatively high at the level of two high pressure seal systems located on either side of the high pressure chamber.

- the apparatus 1 comprises an intake system 2 communicating with the first compression chamber 3 and which is configured to allow the entry of fluid to be compressed into said first compression chamber 3.
- the intake system 2 may for example comprise at least one of: one or more non-return valves, one or more orifices or lumens, at least one flat disc valve or any other device or valve allowing the fluid entry to be compressed into the first compression chamber 3 during an intake phase and preventing the fluid from entering the compression phase.
- this system 2 opens in the event of a determined pressure differential between its two ends.

- the compression stroke in the second compression chamber 4 is upward (traction of the piston rod 5 upwards and towards the hot part of the device 1).
- this upward stroke of the piston 5 during high pressure compression generates a tensile force on the piston rod.
- the rod is not subjected to buckling during this traction (unlike compression / thrust).
- this arrangement of tensile compression does not require guiding the piston rod regularly over its length. This also makes it possible to reduce the area of the section of the piston rod (by hollowing out the rod or reducing its diameter, for example). In addition, this makes it possible to reduce the length of the piston rod according to the acceptable level of heat loss.
- the piston 5 can be driven by an actuator 21 such as a motor located in the upper part of the apparatus 1.
- the piston 5 can be mechanically connected to an actuator 21 via at least one pin 23 arranged around the upper cavity 24 (that is to say at least one pin 23 extending longitudinally around the upper cavity) .
- pins 23 are connected on the one hand to a lower end of the piston 5 and, on the other hand, to a plate 27 or support integral with a shaft 26 connected to the actuating member 21.
- the structure is shaped to allow the sliding of the piston 5 relatively in the plate 24 (or other (s) support (s)).
- the pins 23 can be shaped to slide through a fixed support (not shown) for holding the plate 24.
- the piston 5 may comprise at least one internal duct 25 providing the fluidic connection between the first 3 and second 4 compression chambers.
- the transfer system 6 can be located at the upper end of the piston 5, for example at the upper end of the internal duct 25 opening into the second compression chamber 4.
- the second sealing system 10 formed between the piston 5 and a wall of the upper cavity 24 is located only at the level of the lower end of the second compression chamber 4 and / or below the second chamber 4. compression.
- This architecture thus makes it possible to provide a single dynamic sealing system at high pressure at a single end (lower) of the second compression chamber 4.
- this high pressure sealing system 10 can be located only at the level of the lower end of the second compression chamber 4 and / or below the second chamber

- the actuator 21 (motor or other) is advantageously located outside the enclosure 13, in the upper part of the compression apparatus and the two compression chambers 3, 4 in the enclosure 13.
- Cold fluid at low pressure located at the bottom of the enclosure 13 can be admitted into the first compression chamber 3 via the intake system 2 when the piston 5 rises (and the fluid is pressurized in the second compression chamber 4) cf. [Fig. 3].
