The properties of natural petroleum and petroleum products make use of the True Boiling Point (TBP) distillation analysis and it has been proved to be very useful for petroleum characterization and design and operation of refinery units. So, the TBP distillation analysis has contributed to the petroleum science and technology, to the classification of petroleum, to the development of petroleum property correlations and it has been used worldwide. However, when applied to heavy petroleum fractions, difficulties are often encountered. Through petroleum distillation curve (TBP), it is possible to evaluate the yields of the products that will be obtained in the refineries, as well as to establish operational strategies and process optimizations, as the cracking process. The TBP curve is very important for the oil industry and is used to understand the behavior of oil before distillation. For when the oil is subjected to a distillation tower on an industrial scale is already known about the percentage of distillate obtained working at a specific temperature. In the oil refining industry as the distillations follow: Atmospheric Distillation (distillation up to 673 K - ASTM D 2892) and vacuum distillation (distillation to 838K - ASTM D 5236). This work creates the possibility of extending the temperature range of distillation of oil to 973K. The goal of this work is extend the TBP by DESTMOL, the extension of the TBP curve oil reaching approximately 973 K exceeding the curves generated so far that reach only 838 K. The DESTMOL correlation applies pretty good showing continuity and asymptotic profile of the TBP curve. The results help to meet the waste oil and can thus use the waste for more noble ends. As the result of DESTMOL, we can better define the strategiesand operating conditions for oil processing, achieving better economic results in the use of heavy oil, due to its better characterization.
