Methane Biofiltration in the Presence of Non-Methane Organic Compounds in Solution Gas
Bibliographic record
Abstract
Solution gas is a natural gas consisting of primarily methane and small amounts of non-methane organic compounds. When the amount of solution gas released at individual locations is relatively small and the quality is low, it is not economically feasible to recover this gas. Therefore, environmentally acceptable methods are needed for their control. This research is focused on assessing the viability of using methane biofiltration technology to control point source, low volume solution gas emissions. Unlike the systems with which methane biofilters have already been tested, solution gas contains diverse pollutants in addition to methane, particularly hydrogen sulfide and non-methane organic compounds. A comprehensive set of laboratory experiments were undertaken and the results showed that methane oxidation is not affected by the presence of low concentrations of ethane and propane that could be present in solution gas. However, in flow-through column experiments, the methane oxidation efficiency was adversely affected by increasing the inlet loading rate of ethane. Keywords: Greenhouse gas, methane biofiltration, MMO, NMOC, solution gas, trace gases.

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.
