چکیده

This study investigates the application of machine learning techniques to predict and regulate the outlet temperature of the propane cooling exchanger in the dehydration unit of the South Pars Gas Refinery. Given the critical role of this exchanger in managing gas temperature and preventing operational issues, such as excessive water vapor in molecular sieve dryers, the research focuses on evaluating the effectiveness of three machine learning algorithms: Random Forest, K-Nearest Neighbors (KNN), and Support Vector Machines (SVM). A total of ۳۱۶۸ data points were collected from the refinery's Data Collection System (DCS) for each input, and eleven input variables were used for training and testing the models. The models' performance was assessed using Mean Squared Error (MSE) and R² metrics. The results indicate that Random Forest outperforms both KNN and SVM, providing the best prediction accuracy with a low MSE of ۰.۰۰۳ and a high R² of ۰.۹۲۹. This highlights the potential of machine learning models for optimizing temperature control in industrial processes. The study concludes that Random Forest is the most suitable model for this application, though further exploration of alternative models and techniques is recommended for enhanced performance in different operational contexts.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
