Abstract

Le système de refroidissement d'un flux gazeux principal (A), comporte un évaporateur (1) qui comprend une entrée (11), une sortie (12) et un échangeur dans lequel circule un fluide, et qui permet de refroidir un flux gazeux (B) circulant à travers l'évaporateur entre l'entrée et la sortie de l'évaporateur, un mélangeur (2) comprenant une entrée principale (21) destinée en fonctionnement à être alimentée avec le flux gazeux principal (A), une entrée secondaire (22) et une sortie (23) qui est raccordée à l'entrée (11) de l'évaporateur (1), et des moyens de recyclage (3) d'une partie du flux gazeux refroidi (C), qui ont pour fonction de prélever une partie du flux gazeux refroidi (C) en sortie de l'évaporateur (1) sous la forme d'un flux gazeux recyclé (D) et de rediriger ce flux gazeux recyclé (D) jusqu'à l'entrée secondaire (22) du mélangeur. Le mélangeur (2) permet en fonctionnement de mélanger le flux gazeux principal (A) et le flux gazeux recyclé (D) de plus faible température, de manière à obtenir à l'entrée de l'évaporateur (1) un flux gazeux secondaire (B) plus homogène.The cooling system of a main gas flow (A), comprises an evaporator (1) which comprises an inlet (11), an outlet (12) and an exchanger in which a fluid circulates, and which makes it possible to cool a gas stream (B) flowing through the evaporator between the inlet and the outlet of the evaporator, a mixer (2) comprising a main inlet (21) intended in operation to be supplied with the main gas flow (A), an inlet secondary (22) and an outlet (23) which is connected to the inlet (11) of the evaporator (1), and means for recycling (3) part of the cooled gas stream (C), which have function of taking a part of the cooled gas flow (C) at the outlet of the evaporator (1) in the form of a recycled gas flow (D) and redirecting this recycled gas flow (D) to the inlet secondary (22) of the mixer. The mixer (2) makes it possible in operation to mix the main gas flow (A) and the recycled gas flow (D) of lower temperature, so as to obtain at the inlet of the evaporator (1) a secondary gas flow ( B) more homogeneous.
