Studies of Crosslinked Quaternized Biopolymer for Separation of Heat Stable Salts in Amine Absorption Solution for Carbon Dioxide Capture
Bibliographic record
Abstract
A solid adsorbent, namely, a crosslinked quaternized biopolymer containing hydroxide counterions, such as crosslinked quaternized biopolymer-OH was used to remove heat stable salts (HSSs) from amine used in the CO 2 capture process. The degree of quaternization (DQ) was 60.57 ± 0.39%. The separation of HSSs formate, acetate, propionate, butyrate, glycolate, oxalate, succinate, sulfate, sulfite, and thiosulfate in 5 kmol/m3 monoethanolamine (MEA) using an adsorbent was tested. The removal efficiency for all HSSs were found to initially increase but later level off with contact time. An increase in temperature increased HSSs removal efficiency showing an endothermic nature of the adsorption.

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.
