“…Thus it was more appropriate to choose C 6 H 12 as entrainer for the MPA production process. [31][32][33][34] In this work, taking the esterification of MP and HAC to MPA as the model reaction (Scheme 1), with the purpose of increasing the reaction conversion and preventing the catalyst from deactivation at high temperature, a process combining low-temperature reactive and extractive distillation was investigated by process simulations and experiment methods for the first time. The kinetics of the esterification reaction for MPA was studied in a batch reactor.…”

BACKGROUND Esterification of methoxy propanol (MP) and acetic acid (HAC) to methoxy‐2‐propyl acetate (MPA) is a typical reversible reaction. The yield of MPA is low owing to the limitation of chemical equilibrium. In the present study, with the goal of increasing the reaction conversion and preventing the NKC‐9 cation exchange resin catalyst from deactivation at high temperature, a process combining low‐temperature reactive and extractive distillation with cyclohexane (C6H12) as entrainer was investigated by process simulations and experiment methods. RESULTS The intrinsic kinetic parameters were obtained by catalyst activity evaluation in a batch reactor. Binary interaction parameters of thermodynamic models were determined by the measurement and fitting of vapor–liquid equilibrium data. The effects of different operating parameters on the reaction conversion and column performance were examined in detail, and a production process of MPA with an annual output of 56 000 tons was suggested. The results showed that the purity of MPA reached nearly 100% after further purification following reactive distillation, and the reaction temperature was controlled in the range 75–80 °C, which allowed long‐term operation thermal stability of the catalyst. CONCLUSION The developed low‐temperature reactive distillation method ensured a long life of the ion exchange resin catalyst, which should provide insights into further advances of MPA industrial production. © 2019 Society of Chemical Industry

As the technology is emerging, the process industries are actively migrating to Industry 4.0 to optimize energy, production, profit, and the quality of products. It should be noted that real-time process monitoring is the area where most of the energies are being placed for the sake of optimization and safety. Big data and knowledge-based platforms are receiving much attention to provide a comprehensive decision support system. In this study, the Advanced Advisory system for Anomalies (AAA) is developed to predict and detect the abnormal operation in fired heaters for real-time process safety and optimization in a petrochemical plant. This system predicts and raises an alarm for future problems and detects and diagnoses abnormal conditions using root cause analysis (RCA), using the combination of FMEA (failure mode and effects analysis) and FTA (fault tree analysis) techniques. The developed AAA system has been integrated with databases in a petrochemical plant, and the results have been validated well by testing the application over an extensive period. This AAA online system provides a flexible architecture, and it can also be integrated into other systems or databases available at different levels in a plant. This automated AAA platform continuously monitors the operation, checks the dynamic conditions configured in it, and raises an alarm if the statistics exceed their control thresholds. Moreover, the effect of heaters’ abnormal conditions on efficiency and other KPIs (key performance indicators) is studied to explore the scope of improvement in heaters’ operation.
