Abstract
The gas absorption process for CO 2 separation from gas streams is of high interest in various applications in chemical, oil, and gas industries, as well as in environmental protection. The choice of a certain amine (single or blended amine) for CO 2 capture is mainly based on the absorption capacity, reaction kinetics, and regenerative potential and facility. The application of sterically hindered amines in gas-treating technology offers absorption capacity, absorption rate, and degradation resistance advantages over conventional amines for CO 2 removal from gases. The aim of this review is to bring an update of different aspects concerning several binary and multicomponent systems of CO 2 -sterically hindered amine-based absorbents essential for the design and operation of absorption equipment (physical properties like density, viscosity, vapor pressure, heat capacity and heat of absorption, CO 2 and amine diffusivity, CO 2 absorption capacity and kinetics, regeneration capability).

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
