A knowledge graph framework for digital twins of chemical processes
This article introduces a knowledge graph framework with autonomous functional agents for developing digital twins of chemical processes. It integrates chemical databases, AI models, and large language models, using ontologies for physical models to enable scalable model construction and calibration. The framework is demonstrated with case studies in bottom-up model assembly, top-down model search, and model-based reaction optimization, aiming to manage models as a repository of chemical process knowledge for future development and manufacturing.

Annular Microreactor Optimization
The framework successfully applied the bottom-up model assembly approach to characterize the micromixing performance of an annular microreactor using the Villermaux-Dushman reaction, demonstrating precise mixing time predictions (0.1-10 ms) and excellent agreement with experimental data after calibration.
Taylor-Couette Reactor Model Search
Utilized the top-down model search approach for a ribbed Taylor-Couette Reactor, identifying optimal dispersion coefficient laws across varying operational scenarios (e.g., different solvents and rotation speeds), reducing MAPE to 2.8-7.2% and ensuring model interoperability.
Functional agents for assembly, calibration, rule inference, database access, AI integration, and LLM utilization.
Both bottom-up and top-down strategies for constructing models based on the knowledge graph framework.
