Title
(EN) PROCESS FOR UTILIZING OF MULTI STAGE COMPRESSORS INTERCOOLERS BLOWDOWN AS A COOLANT FOR PROCESS AIR
(FR) PROCÉDÉ D'UTILISATION DE PURGE DE REFROIDISSEURS INTERMÉDIAIRES DE COMPRESSEURS À PLUSIEURS ÉTAGES COMME AGENT DE REFROIDISSEMENT POUR LE TRAITEMENT D'AIR
Abstract
(EN)
A system and a method for processing air prior to separating components of the air are disclosed. The system comprises an air cooler, one or more compression stages operated in series, and one or more intercoolers installed between two adjacent compression stages. A blowdown storage tank is configured to collect water blowdown from one or more intercoolers and provide cooling medium to the air cooler. Atmospheric air is first sprayed by the water blowdown in the air cooler to form a cooled air stream. The cooled air stream is subsequently compressed in the one or more compression stages and cooled by the intercoolers between two adjacent compression stages. The water blowdown from one or more of the intercoolers is collected and recycled as the cooling medium to cool the atmospheric air before it enters the first compression stage.

L'invention concerne un système et un procédé de traitement de l'air avant la séparation des composants de l'air. Le système comprend un refroidisseur d'air, un ou plusieurs étages de compression actionnés en série, et un ou plusieurs refroidisseurs intermédiaires installés entre deux étages de compression adjacents. Un réservoir de stockage de purge est configuré pour collecter de l'eau provenant d'un ou de plusieurs refroidisseurs intermédiaires et pour fournir un milieu de refroidissement au refroidisseur d'air. De l'air atmosphérique est d'abord pulvérisé à l'eau de purge dans le refroidisseur d'air pour former un flux d'air refroidi. Le flux d'air refroidi est ensuite comprimé dans un ou plusieurs étages de compression et est refroidi par les refroidisseurs intermédiaires entre deux étages de compression adjacents. L'eau de purge provenant d'un ou plusieurs des refroidisseurs intermédiaires est collectée et recyclée en tant que milieu de refroidissement pour refroidir l'air atmosphérique avant son entrée dans le premier étage de compression.
