Experimental Evaluation of H2S Yields during Thermal Recovery Processes
Bibliographic record
Abstract
Abstract Experimental techniques have been developed to quantitatively evaluate in-situ H2S generation as a function of solution alkalinity, SO42− concentration, and carrier gas during thermal recovery processes. Experimentally, well-designed laboratory tests have been conducted to quantify the in-situ generation of H2S in a surface passivation reactor. The reaction gases were analyzed by using a gas analyzer, while the pH values were measured by using a glass electrode after adding anions or cations into the solution. Solution alkalinity is found to restrain the formation of H2S after subtracting the amount of H2S that neutralizes alkali in the solution. H2S production increases with increasing SO42− concentrations, more evidently at a high temperature. As temperature increases, using either carbon dioxide or nitrogen as carrier gas increases the H2S production; carbon dioxide as a carrier gas, however, yields more H2S up to 57.6% than nitrogen at temperature of 200-280°C. It is suggested that effect of pH of the formation water be taken into account while predicting the produced acid gas rates.

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.
