This invention relates to process for liquefying a pressurized gas stream rich in methane. In a first step of the process, a first fraction (13) of a pressurized feed stream, preferably at a pressure above 11,000 kPa, is withdrawn and entropically expanded (70) to a lower pressure to cool and at least partially liquefy the withdrawn first fraction. A second fraction (12) of the feed stream is cooled by indirect heat exchange (61) with the expanded first fraction (15). The second fraction (17) is subsequently expanded (72) to a lower pressure, thereby at least partially liquefying the second fraction (17) of the gas stream. The liquefied second fraction (37) is withdrawn from the process as a pressurized product stream having a temperature above -112 °C and a pressure at or above its bubble point pressure.

La présente invention concerne un procédé de liquéfaction d'un flux de gaz sous pression riche en méthane. Dans ce procédé, une première fraction (13) d'un flux d'alimentation sous pression, de préférence à une pression supérieure à 11,000 kPa, est retirée et subit une détente (70) par entropie jusqu'à une pression inférieure pour la refroidir et la liquéfier en partie. Puis, une seconde fraction (12) du flux de gaz sous pression est refroidie par échange thermique indirect (61) avec la première fraction (15) ainsi détendue. La seconde fraction (17) de flux de gaz subit ensuite une détente (72) jusqu'à une pression inférieure, en vue de la liquéfier. La seconde fraction liquéfiée (37) est retirée du processus sous forme de flux de produit sous pression présentant une température au-dessus de -112 DEG C et une pression égale/supérieure à sa pression de point de bulle.
