Abstract
This work employed the Analytical Hierarchy Process (AHP) to investigate the advantages and disadvantages of polypropylene production reactors. Five criteria were considered for this process, and three alternatives were evaluated based on the AHP method. Then, the polypropylene production process was simulated and, ultimately, the operational conditions were optimized. The tubular reactor was identified as the highest priority alternative, and cost was the highest priority criterion in the process, with 38% and 25%, respectively. The percentage of polymer yield from the reactor and the reduction of operational costs were chosen as the objective functions of this process. The optimization results showed that the best feed gas temperature and mass flow rates were 78 degrees Celsius and 5000 Kilograms per hour, respectively. Additionally, by reducing operational costs as an objective function at the optimal point, energy savings of up to 78102 dollars per year can be achieved.
