Abstract
This study introduces a Reinforcement Learning (RL) approach for synthesis, design, and control of chemical process flowsheets (CPFs). The proposed RL framework makes use of an inlet stream and a set of unit operations (UOs) available in the RL environment to build, evaluate and test CPFs. Moreover, the framework harnesses the power of surrogate models, specifically Neural Networks (NNs), to expedite the learning process of the RL agent and avoid reliance on mechanistic dynamic models embedded within the RL environment. These surrogate models approximate key process variables and descriptive closed-loop performance metrics for complex dynamic UO models. The proposed framework is evaluated through case studies, including a system where more than one type of UO is considered for simultaneous synthesis, design and control. The results show that the RL agent effectively learns to maintain the dynamic operability of the UOs under disturbances, adhere to equipment design and operational constraints, and generate viable and economically attractive CPFs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
