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.A method of liquefying a stream of hydrocarbons from a feed stream comprising at least the following steps: Step a): passage of the feed gas against a mixed refrigerant stream through a heat exchanger to provide a at least partially liquefied hydrocarbon stream having a temperature below - 140 ° C; Step b): extraction of a mixed refrigerant stream from the heat exchanger from an outlet where the temperature in the heat exchanger is the highest; Step c): introduction of the mixed refrigerant from step b) into a phase separating means in order to produce a gaseous refrigerant stream and a first liquid refrigerant stream; Stage d): passage of the first liquid refrigerant stream from stage c) through the heat exchanger from a first inlet and up to a so-called intermediate outlet beyond which the refrigerant stream thus obtained is expanded , the temperature T1 at said outlet being such that said expansion produces a gas fraction of less than 20%; Stage e): passage of the gaseous refrigerant stream from stage c) through the heat exchanger from an inlet and up to an outlet at a temperature T3, the level of which is the lowest of the temperature levels of said heat exchanger.
