Abstract
La présente invention concerne un procédé de liquéfaction de gaz naturel, qui est simple en ce qu'il comprend un seul cycle de réfrigération, ce qui permet d'obtenir un système de liquéfaction compact et facile à exploiter. Le procédé assure une excellente efficacité de liquéfaction de gaz naturel en ce qu'il permet: d'utiliser un moyen de séparation pour séparer avec précision un fluide frigorigène en une partie principale lourde et une partie principale légère, dans la composition requise; de prérefroidir le gaz naturel avec un flux de fluide frigorigène dans une première zone d'échange de chaleur, et de liquéfier le gaz naturel avec l'autre flux de fluide frigorigène dans une seconde zone d'échange de chaleur.
