Title
(EN) METHOD OF CONTROLLING A COMPRESSOR SYSTEM AND COMPRESSOR SYSTEM
(FR) PROCÉDÉ DE COMMANDE D'UN SYSTÈME DE COMPRESSEUR ET SYSTÈME DE COMPRESSEUR
Abstract
(EN)
The disclosure includes controlling a pressure ratio for a compressing system, comprising introducing a quantity of liquid into an input stream to create a multiphase input stream, compressing the multiphase input stream with a centrifugal compressor to create a discharge stream, measuring a parameter of the discharge stream, wherein the discharge parameter corresponds to a pressure ratio for the centrifugal compressor, when the parameter exceeds a first predetermined point, increasing a pressure ratio of the centrifugal compressor by increasing the quantity of liquid introduced, and when the parameter exceeds a second predetermined point, decreasing the pressure ratio by decreasing the quantity of liquid introduced.
(FR)
L'invention comprend la commande d'un rapport de pression pour un système de compression, comprenant l'introduction d'une quantité de liquide dans un courant d'entrée afin de créer un courant d'entrée à phases multiples, la compression du courant d'entrée à phases multiples avec un compresseur centrifuge de façon à créer un courant de décharge, la mesure d'un paramètre du courant de décharge, le paramètre de décharge correspondant à un rapport de pression pour le compresseur centrifuge, et, quand le paramètre dépasse un premier point prédéterminé, l'augmentation d'un rapport de pression du compresseur centrifuge par l'augmentation de la quantité de liquide introduit, et, quand le paramètre dépasse un second point prédéterminé, la diminution du rapport de pression par la diminution de la quantité de liquide introduit.
