Abstract
Abstract Simulation of a Vinyl Acetate Monomer (VAM) process design is developed in this work to allow testing of two advanced control strategies within the base PI control scheme Specifically, the two schemes focus on improving the control performance of the azeotropic distillation column A detailed steady‐state and dynamic analysis of the distillation column has been performed to provide insight into the control behaviour of the two composition loops The possible benefits from this type of study include production increase, safer operation and lower operating cost To the authors' knowledge, this paper represents the first time a ratio control scheme and a model predictive controller (MPC) have been applied to the VAM process and presented in the open literature Simulation results are presented to illustrate the effectiveness of the new control strategies

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
