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.

- 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.
