Abstract

Le procédé consiste notamment à :- déterminer une caractéristique de fonctionnement de la source de fluide,- maintenir, tant que la caractéristique de fonctionnement possède une valeur inférieure à une valeur dite seuil, le débit (Q1) du flux prioritaire (S1) sensiblement égal au débit (QE) du flux d'entrée (E) et le débit du flux secondaire (S2) à une valeur nulle,- répartir le flux d'entrée (E) entre le flux prioritaire (S1) et le flux secondaire (S2), lorsque la caractéristique de fonctionnement possède une valeur supérieure à la valeur seuil (V1), en faisant varier le débit (Q1) du flux prioritaire (S1) en fonction de la valeur de la caractéristique de fonctionnement de la source de fluide (2).
