Zusammenfassung:	The invention relates to a method and system for cooling a natural gas feed stream and recovering a natural gas liquid stream from the natural gas feed stream using an expansion-based cooling unit and a natural gas liquid removal unit which are integrated. The integration is done by using (part of) a cooling stream from the expansion-based cooling unit to provide cooling duty to the natural gas liquid removal unit. La présente invention concerne un procédé et un système pour refroidir un courant d'alimentation en gaz naturel et récupérer un courant de liquide de gaz naturel à partir du courant d'alimentation en gaz naturel à l'aide d'une unité de refroidissement à base d'expansion et d'une unité d'élimination de liquide de gaz naturel qui sont intégrées. L'intégration est réalisée en utilisant un courant de refroidissement (ou une partie de celui-ci) provenant de l'unité de refroidissement à base d'expansion pour fournir un service de refroidissement à l'unité d'élimination de liquide de gaz naturel.
