Device and process for cooling a flow of a target fluid predominantly comprising dihydrogen, and associated use thereof

Abstract

The device (100) for cooling a flow (101) of a target fluid predominantly comprising dihydrogen, comprises: a first heat exchanger (105) configured to cool an intermediate refrigerant fluid (110) by heat exchange with an expanded dioxygen flow (115), an intermediate closed circuit (120) for transporting the intermediate refrigerant fluid from the first heat exchanger to a second heat exchanger (125), a means (130) for compressing the intermediate refrigerant fluid along the intermediate closed circuit, the intermediate refrigerant fluid, configured to remain in the liquid or supercritical state at least upon passing through the compression means and the second heat exchanger configured to cool the target fluid flow by heat exchange with the intermediate refrigerant fluid cooled in the first heat exchanger.
