Abstract
This study developed the presented process simulation based on the design parameters of typical gas plant CCS units in North America. Since the recovered waste heat technology is a new commercial design in solvent regeneration processes, the parametric sensitivity study could provide several detailed optimization methods for further operations. The parametric analysis was conducted by varying MEA concentration (5–7.5 M), the inlet temperature of rich solvent (105–110°C) and reboiler temperature (122–127°C). Additionally, this study developed two split-flow process configurations based on the existing columns and operational conditions. The application of a split-flow configuration with the proper solvent concentration has the potential to save up to 40% of energy costs. The work also evaluated the factors that influence overall capture performance such as column size, type of amine and solvent flow rate. It is promising that the split-flow process configuration and solvent concentration are two potential optimization routes for further practical operations.

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
