Understand the advantages of using First Principles Driven Hybrid Models. Develop accurate hybrid models using both mechanistic and AI/ML fundamentals. Build and deploy predictive hybrid models within process simulators to improve accuracy for several units such as distillation columns, reactors, heat exchangers, pressure changers, separators, etc. Use plant data to replace inadequately modeled relationships not fully captured by traditional engineering models. |
