Effect of additives on formation and decomposition kinetics of methane clathrate hydrates: Application in energy storage and transportation
Bibliographic record
Abstract
Abstract Methane gas storage and transportation via clathrate hydrates is proposed to be a potential solution for large‐scale energy storage. In this work, we study the formation and decomposition kinetics of methane hydrates (MH) in a laboratory‐scale unstirred crystallizer. The present investigation demonstrates comparative studies of hydrate formation and dissociation kinetics in the presence of tetrahydrofuran (55.6 and 27.8 mmol/mol, 5.56 and 2.78 mol % THF) and sodium dodecyl sulphate (1 mg/g, 0.1 wt% SDS). Moreover, the storage capacity and hydrate formation kinetics in both the systems are discussed. In a recent work, enhanced methane hydrate growth in the presence of THF at close to atmospheric conditions was demonstrated. The emphasis of the current work is to study the stability of hydrates to understand dissociation kinetics by measuring the rate of hydrate decomposition at different temperatures. Hydrate stability measurements were performed at −8, −3, 2, 10, and 20 °C to study the decomposition rates of MH and self‐preservation in presence of the two additives THF and SDS.

How this classification was reachedexpand
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.
