Abrégé
(EN)
The present invention relates to a process for controlling the antifoam injection based on the pressure differential of the column. More specifically, the present invention relates to a process for controlling the antifoam injection based on the pressure differential of an aromatics extraction unit using an intelligent differential pressure transmitter. The controller communicates with the antifoam injection system so that the antifoam is injected to the unit only when it is required.
(FR)
La présente invention concerne un procédé de commande de l'injection anti-mousse sur la base du différentiel de pression de la colonne. Plus spécifiquement, la présente invention concerne un procédé de commande de l'injection anti-mousse basé sur le différentiel de pression d'une unité d'extraction de composés aromatiques à l'aide d'un émetteur de pression différentielle intelligent. Le dispositif de commande communique avec le système d'injection anti-mousse de sorte que l'agent anti-mousse est injecté dans l'unité uniquement lorsque cela est nécessaire.
