Definitions
- This presentation relates to the compression of a gas and in particular the recovery of gas compression energy.
- the liquefaction of a gas generally requires a step of compressing the gas at high pressure.
- This compression stage is qualified as isothermal and is generally carried out by a succession of adiabatic compression stages during which the gas is heated. Thus, between each compression stage, the gas is cooled before entering the next compression stage.
- the gas is cooled in a heat exchanger.
- liquefiers also called “liquefier” in English
- the heat recovered in this heat exchanger is either lost to the atmosphere or, for example as described in JP2005241232, used as a hot source for the vaporization of natural gas liquid.
- the liquefier-liquefied natural gas installation coupling implies that the liquefier and the liquefied natural gas installation are in the same place. Also, this heat recovery solution greatly limits the possibility of recovering this heat, in particular the number of liquefied natural gas installation sites, the fluctuation in demand for liquefied natural gas which will have an impact on cooling compressed gas between two compression stages as well as safety constraints linked to the presence of liquefied natural gas and liquid hydrogen, for example.

- the hot source is the gas leaving a compression stage of the adiabatic compressor.

- the electrical energy produced can be used to supply components of the liquefier itself or components external to the liquefier, or even be injected into the electrical network.
- the energy recovery can be around 2% to 5% of the power required to operate the liquefier, which is not negligible with regard to the service life of a liquefier, which can be at least 20 years.
- the gas may be the gas to be liquefied.
- the liquefier may be a refrigerated liquefier comprising at least one cooling circuit and the gas is the gas from the at least one cooling circuit of the refrigerated liquefier and/or the gas to be liquefied.
