Performance investigation of a new renewable energy‐based carbon dioxide capturing system with aqueous ammonia
Bibliographic record
Abstract
In this study, a novel wind energy-based carbon dioxide (CO2) capturing system is developed and investigated for practical applications to reduce environmental emissions. The aqueous ammonia-based capturing technology is utilized. Wind turbines are used to operate the onsite ammonia synthesis as well as hydrogen production. The proton exchange membrane electrolysis system is considered for hydrogen production and the Haber-Bosch ammonia synthesis technique is utilized. The developed system is modeled in Aspen Plus software. The system performance for CO2 capture is studied through economic, energy, and exergy perspectives. The CO2 capture cost is evaluated to be between 0.1 and 0.23 $/kg CO2. Furthermore, the system CO2 capture rate is determined to be 3.5 kg/s. Moreover, for a unit mass of CO2 captured, the energy consumption is found to be 640.1 kg CO2/MWh. Several parametric studies are also conducted to analyze the effects of varying operating conditions on the system performance.

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.
