Abstract

Procédé de liquéfaction d'un courant d'hydrocarbures à partir d'un courant d'alimentation comprenant au moins les étapes suivantes : Etape a) : passage du gaz d'alimentation contre un courant réfrigérant mixte à travers un échangeur de chaleur pour fournir un flux d'hydrocarbures au moins partiellement liquéfié ayant une température inférieure à - 140°C ; Etape b) : extraction d'un courant réfrigérant mixte de l'échangeur de chaleur à partir d'une sortie où la température dans l'échangeur de chaleur est la plus élevée; Etape c) : introduction du réfrigérant mixte issu de l'étape b) dans un moyen séparateur de phases afin de produire un courant réfrigérant gazeux et un premier courant réfrigérant liquide; Etape d) : passage du premier courant réfrigérant liquide issu de l'étape c) dans l'échangeur de chaleur à partir d'une première entrée et jusqu'à une sortie dite intermédiaire au-delà de laquelle le courant réfrigérant ainsi obtenu est détendu, la température T1 à ladite sortie étant telle que ladite détente produit une fraction gaz inférieure à 20% ; Etape e) : passage du courant réfrigérant gazeux issu de l'étape c) dans l'échangeur de chaleur à partir d'une entrée et jusqu'à une sortie à une température T3 dont le niveau est le plus bas des niveaux de température dudit échangeur de chaleur.
