Membrane contacting process for CO2 desorption
Bibliographic record
Abstract
A membrane contactor based desorption process was developed to strip carbon dioxide (CO 2 ) from loaded monoethalamine (MEA) solution. Nitrogen (N 2 ) gas was used as a stripping gas instead of steam in a conventional column. Polytetrafluoroethylene (PTFE) hollow fiber membranes were used to test the desorption performance. The liquid solution was fed in the lumen while the stripping gas was fed through the shell side. The stripping gas, liquid velocities, operating temperature, and MEA concentration were all investigated for their effect on CO 2 desorption flux. It was found that the CO 2 desorption flux was relatively constant with an increase stripping gas velocity while the liquid velocity, operating temperature, and solution concentration could enhance CO 2 desorption flux in the membrane contactor based desorption process. However, an increase the solution concentration to 5 kmol m 3 resulted in a decrease in the CO 2 desorption flux due to the effect of viscosity.

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.
