| Popis: | The primary objective of this study is to predict the optimum operating conditions required tooperate an existing atmospheric distillation column to distillate heavier crude oils in same unit whichdesigned mainly to fractionate moderate and lighter crude oils.Detailed simulation model of atmospheric distillation column was made using Aspen Hysys V.8.4 software. The model built depending on the data of real plant which located in Al-Daura midlandrefinery company at Baghdad/Iraq. The crude oils were described using the true boiling point (TBP)assays and Peng-Robinson package were used to predict thermodynamic properties. Three differenttypes of crude oils (Kirkuk light, Basrah light and Basrah medium) were selected to identify themodel validity. The simulation results agree very well with the industrial plant results. Finally theproposed model was used to predict optimum operating conditions required to distillate a blend oflight and heavy Basrah crude oil with different mixing ratios. The objective of the optimization is topredict the maximum profit of the products within the required specifications. At optimum operatingconditions the total yearly profit for distillation of a blend of 50% vol. light+50% vol. heavy basrahcrude oil was found to be 713.28 M$. |
