Abstract

fetched live from OpenAlex

Abstract Australian crude oils, which generally contain little asphaltenes, nevertheless give rise to fouling in refinery pre-heat trains. In this research, the fouling of a series of such crude oils and their blends is being assessed. The present work focuses on thermal fouling resulting from heating Gippsland crude oil at moderate temperatures. The oil is maintained under nitrogen at a pressure of 379 kPa and re-circulated at bulk temperatures of 80–120ˆC through an electrically heated annular probe at velocities in the range 0.25–0.65 m/s with surface temperatures from 180–260ˆC. Experiments are run for periods up to ninety hours at constant heat flux. Fouling is detected by the increase of wall temperature of the probe. The oil is characterized by its filterable solids content, density, and viscosity both before and after the fouling run. The trends in fouling rates are compared to predictions of the threshold-fouling model proposed by Ebert and Panchal [6] Ebert, W. A. and Panchal, C. B. 1995. “Analysis of Exxon Crude Oil Slip-Stream Coking Data”. In Fouling Mitigation of Industrial Exchange Equipment, Edited by: Panchal, C. B. pp. 451–460. New York: Begell House. [Google Scholar]. Data on deposit composition are presented, and the fouling mechanism is discussed.

Teacher imitation

Not 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.
