Experimental Investigation of Methane Hydrates Equilibrium Condition in the Presence of KNO<sub>3</sub>, MgSO<sub>4</sub>, and CuSO<sub>4</sub>
Bibliographic record
Abstract
A new isochoric reactor was commissioned for studying gas hydrate equilibrium formation, and experiments were carried out to measure the equilibrium conditions for methane hydrate formation in aqueous solutions of CuSO 4, KNO 3, and MgSO 4 . The experimental conditions ranged from (273 to 281) K in temperature and between (3 and 6) MPa in pressure, and the mass fraction of salt ranged from (0.025 to 0.402), depending on the salt. In the case of all three salts, it was observed that there was an inhibiting effect on the hydrate formation, which is in contrast to a previous observation that found CuSO 4 had a promoting effect on CO 2 hydrates.

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.
