Evaluasi Performa Furnace EDC (Ethyl Dichloride) Cracker di VCM (Vinyl Chloride Monomer)-1 Plant
Bibliographic record
Abstract
Furnaces in the production of VCM (Vinyl Chloride Monomer) must be operated with optimal efficiency to maximize production and minimize the formation of impurities (coke). Furnace efficiency is evaluated based on the ratio of heat generated from fuel combustion to heat absorbed by the EDC (Ethyl Dichloride) fluid, and is a key indicator of operational feasibility. In addition, the pressure difference of the inlet convection and outlet radiant sections is used as an additional parameter, where an increase in this value reflects the accumulation of deposits in the tubes. If the efficiency drops below the minimum operating conditions or the pressure difference between the convection inlet and outlet radiant section exceeds 4 kg/cm2G, the furnace is considered unfit for operation and decoking must be performed, which will increase operating costs. During the 12 days of monitoring (measurement every 8 hours), the average efficiency was 85.370%, the highest value was 87.348%, and the lowest value was 83.764%. The efficiency values tended to fluctuate and were below the minimum operating condition (88.898%). This is due to changes in operating conditions and manual control. Therefore, although the pressure difference is still below the threshold of 4 kg/cm2G, the furnace is considered unfit for operation.

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.
