Design and study of a novel ammonia‐based <scp> CO <sub>2</sub> </scp> capture process with bipolar membrane electrodialysis
Bibliographic record
Abstract
Abstract Aqueous ammonia is a promising absorbent in the field of post combustion CO 2 capture. However, the high volatilization of NH 3 results in a high energy requirement, as well as solid precipitation during the CO 2 regeneration process. A novel process was designed to reduce energy consumption and solve the problem. The bipolar membrane electrodialysis (EDBM) unit and CO 2 regeneration reactor were taken as the regeneration part. In the novel process, the bubble in the EDBM unit would be eliminated, and the regeneration of CO 2 and aqueous ammonia would be operated separately, which significantly reduced energy consumption and avoided the risk of precipitation during regeneration. According to the simulation and calculation results, the CO 2 regeneration energy consumption of the novel process using H 2 SO 4 for CO 2 regeneration is 39.0% lower than that of the conventional ammonia‐based process, which shows good energy saving potential. Moreover, the novel process will be more competitive as membrane technology develops.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
