This study was conducted at the GL1K complex in Skikda, which specializes in the liquefaction of natural gas. We examined the effectiveness of APC in managing the complex interactions within the process, focusing on key performance indicators such as stability, efficiency, and product quality. The results demonstrated that APC significantly improves process performance and reduces variability compared to conventional PID controllers. This research highlights the advantages of advanced control strategies in optimizing industrial operations and ensuring superior control over multivariable systems.enProcédés de fabrication : AutomatisationAPC (contrôleur)PID (contrôleur)DistillationGaz naturel : LiquéfactionStabilitéPétrochimie : InstrumentationsThesis
