Abstract (en)
[origin: WO2018115659A1] The device (100) for liquefying a natural gas comprises: - a compressor (105) for a first vaporized coolant chemical mixture, - a means (110) for fractionating the compressed mixture into a heavy fraction and a light fraction, - a first heat exchange body (115) for heat exchange between the heavy fraction of the first mixture and the natural gas in order to cool at least the natural gas, - a second heat exchange body (120) for heat exchange between the light fraction of the first mixture and the cooled natural gas in the first exchange body in order to liquefy the natural gas, and - a return pipe (125) for return of the first vaporized coolant mixture in the heat exchange body to the compressor (105), - upstream from an inlet (116) for the natural gas in the first exchange body (115) or downstream from an outlet (121) of liquefied natural gas from the second exchange body (120), a third heat exchange body (130, 135) for heat exchange between the natural gas and a second coolant chemical compound, and - a means (140, 145) for compressing the second vaporized compound.
