Abstract

L'invention concerne un procédé de liquéfaction d'un courant riche en hydrocarbures, en particulier d'un courant de gaz naturel, par échange thermique indirect avec les agents réfrigérants d'une cascade de circuits de mélanges réfrigérants, caractérisé en ce que ladite cascade comprend au moins trois circuits de mélanges d'agents réfrigérants présentant différentes compositions d'agents réfrigérants. A cet effet, le premier des trois circuits de mélanges réfrigérants est utilisé pour le pré-refroidissement (E1), le deuxième, pour la liquéfaction (E2), et le troisième, pour le sous-refroidissement (E3) du courant riche en hydrocarbures à liquéfier (1). Le procédé selon l'invention permet de réduire la consommation d'énergie spécifique et les frais d'investissement, du fait que les trois circuits de mélanges réfrigérants sont adaptés, ou peuvent être adaptés, de façon optimale aux courbes de températures d'enthalpie dudit courant riche en hydrocarbures à liquéfier et des mélanges des agents réfrigérants.
