Abstract

fetched live from OpenAlex

This paper presents a study on the effect of process uncertainty on the optimal design of a CO 2 capture plant. A recent method in the optimal design of large-scale chemical processes under uncertainty, which employs Power Series Expansion (PSE) models to approximate the process constraints, has been used in this work due to its computational benefits. Uncertainty in the CO 2 content in the flue gas stream entering the plant is assumed; the problem under analysis aims to find the most economically feasible design, by sizing the plant's process equipment, as well as obtaining its optimal operating conditions, in the presence of uncertainty. The results show that process uncertainty have a direct effect on the sizes of the absorber and stripper columns and operation of the reboiler duty, whereas the cross heat exchanger and condenser's heat transfer areas are not significantly affected.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
