Abstract

La présente invention a pour objet un procédé de liquéfaction d'un gaz naturel comprenant majoritairement du méthane, dans lequel on liquéfie ledit gaz naturel à liquéfier en réalisant les étapes concomitantes suivantes de : (a) circulation dudit gaz naturel à liquéfier circulant dans 3 échangeurs thermiques montés en série dans lesquels il est refroidit à T3, T3 étant inférieure ou égale à la température de liquéfaction dudit gaz naturel à pression atmosphérique, et (b) circulation à circuit fermé d'au moins: - un premier flux de gaz réfrigérant à une pression PI inférieure à P3 entrant dans le troisième échangeur et sortant dudit premier échangeur, ledit premier flux étant obtenu par détente dans un premier détendeur d'une première partie d'un dit deuxième flux à P3 supérieure à P2, ledit deuxième flux circulant à co-courant dudit flux gaz naturel en entrant dans ledit premier échangeur et sortant dudit deuxième échangeur, et - un troisième flux à une pression P2 supérieure à PI et inférieure à P3 circulant à co-courant dudit premier flux, entrant dans ledit deuxième échangeur et sortant dudit premier échangeur, obtenu par détente dans un deuxième détendeur d'une deuxième partie dudit deuxième flux sortant dudit premier échangeur, (c) ledit deuxième flux de gaz réfrigérant à la pression P3 étant obtenu par compression par au moins deux premier et deuxième compresseurs disposés en série et couplés auxdits premier et deuxième détendeurs.
