摘要：
The device (100) for pre-cooling a flow of a gas comprises:
a separator (135) of a coolant flow (125), downstream from a compressor (155), into two flows:
one coolant flow (140) referred to as “medium-pressure”; and
one coolant flow (145) referred to as “low-pressure”;
a first exchanger (105) exchanging heat between the flow (120) of the gas to be pre-cooled and at least the medium-pressure coolant flow (140) comprising at least nitrogen;
an expander (150) of the low-pressure coolant flow;
a second exchanger (110) exchanging heat between the flow of a gas and the expanded low-pressure coolant flow on output from the second expander; and
a third exchanger (115) exchanging heat between the flow of a gas and the low-pressure coolant flow on output from the second heat exchanger.
