Abstract
This study presents the design and modification of a desalting unit in an existing refinery where crude oil is desalted in a single-stage desalter. The design considers a scheduled increase in the crude feedstock, and change from the current lighter blend to a future heavier blend. A more stringent limit with regard to salt content in the desalted crude is also applied. The simulation studies showed that a second stage electrostatic desalter is required in order to achieve a salt content of one parts per thousand barrel (PTB) compared to the current ten PTB, and starting from a crude oil with 100 PTB. The process was simulated using HYSYS computer software. Calculations related to heat integration of the desalting process to achieve the best operating temperature in the plant are also presented. Mass and heat balances are discussed and several environmental issues are addressed. [Received: October 14, 2009; Accepted: January 13, 2010]

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 it
