Abstract:
The invention concerns a method comprising: (a) a first step whereby natural gas (1) is subjected to a first refrigerating cycle to obtain cooled natural gas (4), and brought to a temperature less than 20° C. by a first coolant (201); a second step whereby the cooled natural gas (4) is subjected to a second refrigerating cycle wherein the cooled natural gas (4) is cooled and condensed by a second coolant (103) comprising methane, ethane, propane, and nitrogen. The second coolant (103) further contains ethylene, the total ethane and ethylene content being close to 50 mole %.
