Application Status of Post-combustion CO2 Capture
Bibliographic record
Abstract
Carbon dioxide (CO2) is a major anthropogenic greenhouse gas. The atmospheric concentration of CO2 has increased from 280 ppm, in the mid-1800s, to about 407 ppm in 2017. Due to the global warming and climate change effect there have been worldwide efforts to control CO2 emission. Pre-combustion capture, post-combustion capture, oxy-fuel combustion, and chemical looping combustion are the technological options currently under consideration for capturing CO2 from combustion and gasification facilities. Carbon capture and storage (CCS) has been accepted as a primary option to mitigate anthropogenic CO2 emissions. There are few large-scale CCS facilities in operation at present: (i) Petra Nova Carbon Capture, Texas, USA; (ii) SaskPower Boundary Dam- CCS; (iii) Kemper County Energy Facility (IGCC + CCS); and (iv) Callide – Oxy-fuel combustion and carbon storage demonstration plant. Furthermore, there have been some emerging small-scale PCC projects, most of which use ammonia or proprietary amines as a solvent.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
