Description:

Marathon Ashland Petroleum (MAP) has improved the property prediction of their LP model by including the effect of imperfect crude unit fractionation predicted by simulation. This model was tuned to match actual plant operation. HYSYS.Refinery was used to generate data required to update the LP. HYSYS.Refinery generated data for the ‘base’ and ‘swing’ operations. The output from the simulation is directly linked to Excel for calculation of swing cuts and transfer to the ‘base’ and ‘swing’ tables in the LP. Volume, specific gravity, sulfur, nitrogen, pour point, cloud point, viscosity, Con carbon, and cetane index were predicted. All but the first two are sensitive to the amount and properties of the material in the ‘tails’ of the distillation. Matching the tails to actual operations gives a more accurate prediction of stream properties, which gives a more accurate LP. MAP was able to show the impact of the more realistic representation of product properties on their overall refinery performance. Moreover, predicting stream properties that match refiners’ experience builds overall confidence in the models.
