Abstract
Abstract The integrated gasification combined cycle (IGCC) offers the opportunity for precombustion CO 2 capture. However, recent studies using physical absorption for CO 2 separation indicated efficiency penalties only slightly lower than those for postcombustion capture in conventional steam power plants. These efficiency penalties are explained and analyzed. As an alternative, a process using a so‐called water‐gas shift membrane reactor, which combines hydrogen‐selective membranes with water‐gas shift reaction, is presented. It is demonstrated that the use of recirculated flue gas from downstream of the heat recovery steam generator as membrane sweep gas results in an overall efficiency loss of only 4.5 %‐points (including CO 2 compression to 120 bar) in comparison to an IGCC without carbon capture and storage (CCS).

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
