Control Rehabilitation Impact on Production Efficiency of Ammonia Synthesis Installation

Abstract: This article presents final technical and economical results of the comprehensive control rehabilitation project done for the ammonia synthesis plant at JP Nawozy, GA ZAK S.A. The project included the following activities: review of the existing control philosophies and instrumentation infrastructure, design and implementation of the new control loop templates, and tuning of the revised controls over the entire installation. These activities improved installation operation with much more reliable and repeatabl… Show more

“…It enables to test the robustness of considered indexes against non-Gaussian properties. On the other hand, it has been shown that α =stable PDF fits the industrial disturbances appearing in chemical engineering [37]. The analysis focuses on an impact of the disturbance asymmetry on the ability to detect the MPC controller wrong tuning through different settings of the skewness factor β.…”

“…Wybór łączy w sobie wskaźniki klasyczne z odpornymi. Wynika to z faktu, że charakter przebiegów często cechuje się właściwościami niegaussowskimi [6,7], a takich przypadkach wskaźniki odporne jak IAE, LMS czy też ADM powinny być lepiej dopasowane.…”
