Abstract

The petroleum gotten in the Brazilian basins is of the types heavy and ultra-heavy, presenting high viscosities that make difficult its exploration (remove of the oil from submarine fields) and also the operations of refining for fuel attainment and other derivatives. The processes of refining, currently in activity, in the refineries, do not allow the heavy and ultra-heavy oil operation, so that these are mixed with light oils for its processing. This procedure leads to the dependence of Brazil in importation of oil, as well as not complete valuation of the oil found in the country. Inside this context, the use of molecular distillation is presented as an alternative to initial operation of heavy and ultra-heavy oil. Experiments carried through in the Laboratories of Development of Processes of Separation (LDPS) and Optimization, Project and Advanced Control (LOPCA) had shown the viability of this operation. However, is necessary an ample inquiry for development of operational politics that take the operation of molecular distillers with high performance for oil refining. For this purpose, the development of simulations that allow an extensive study covering the possible operational bands, that are functions of the characteristics of the oil, is necessary. It is considered thus, in this work, the development of a descendant filmed distiller simulations using the commercial simulator Aspen Plus®, that possess easiness of thermodynamic packages for the accomplishment of the task. Available experimental data were used for the analysis and evaluation of the simulations. (AU)
