Heavy hydrocarbons are the greatest oil resource in the world, however in the past had been put aside as an energy resource due to the difficulties and costs associated with production, [1]. Nowdays, the industry is financing this research because of the importance of production and the characterization. To analyse the vacuum tower, we need ASTMD1160 temperature at 10 mmHg and oil density, thereafter it can be obtained the curve of TBP760 (True Boiling Point). To correlate different boiling points with vaporized percentages for each change of pressure on the products, is necesary to build up a phase diagram with the EFV760 (Equilibrium Flash Vaporization) and EFV10 temperature. The simulator through internal calculations resolves the phase diagram, compared with the difficulty posed by manual calculations. In this paper a vacuum tower simulator is developed by Aspen HYSYS V8.3, and using the heavy oil as input data. The major advantage of the theoretical designed simulation process is the time resolution
