Plant performance test for the de‐ethanizer overhead recycle (DOR) process
Bibliographic record
Abstract
Abstract The de‐ethanizer overhead recycle (DOR) process was successfully performance‐tested at the Joffre ethane extraction plant (JEEP) in Alberta, Canada, in May 2005. The test confirmed simulation results used in patenting the process and were slightly better than predicted. At the lowest test recycle rate, the CO 2 content in the produced ethane was reduced from 5.4 to 4.5 mole% with only a slight drop in ethane recovery from 90.4 to 90.0%. Increasing the recycle to a higher level reduced the CO 2 content to 4.1% at an ethane recovery level of 88.8%. The process showed excellent operability and was effective for reducing both CO 2 and methane from a commercial ethane product stream.

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.
