IMPACT OF CRUDE OIL BLEND VARIATION ON THE RESULTS OF THE DISTILLATION PROCESS AT THE SERGIO SOTO REFINERY

Abstract

Introduction:
It is necessary to increase the quality and production of R3, the main material for the production of dielectric oil at the Sergio Soto Oil Refinery, which may be affected by the availability of raw materials.
Objective:
To evaluate the alternative of mixing national crude, specifically that of the PinaCristales field, with Russian Ural oil.
Materials and Methods:
Three blends of different oils were analyzed using the Aspen Hysys simulator (PinaCristales and Ural, of the latter three varieties that are entering the country), which are evaluated by varying the ratios between them to 7 in different proportions (95:5,
90:10,85:15,80:20,70:30,60:40 and 50:50). With a view to minimizing the import of Ural, the experimental analysis was carried out with a higher proportion of Cuban oil.
Results and Discussion:
The adjustment of the experimental results reported for the three samples yielded that a mixture Pina + UralsexLuga in a ratio of 60 and 40% respectively, with R3 acidity values of 1.5 %, yield of 10% and a total amount of R3 cut of 4 166.66 kg/h is the most
recommendable. For its introduction on an industrial scale, a cost-benefit economic analysis was carried out and the optimal composition of the selected mixture was selected through the derivation of the adjusted regression model.
Conclusions:
For a composition of 62.34% Pina and 38.64% Ural, a maximum profit of 1 896 220.36 USD/year was achieved.
