Determinación de las fracciones de destilación al vacío (371°C - 565°C+) de crudos a partir de modelos predictivos obtenidos por Espectroscopia FTIR-ATR y Quimiometría.

Abstract

This research describes the development and evaluation of predictive models to determine the yields of the vacuum distillation fractions: light distillate (371 ° C - 427 ° C), medium distillate (427 ° C -482 ° C), heavy distillate (482 ° C -565 ° C) and vacuum bottom (565 ° C +); from the infrared spectra obtained by attenuated total reflectance (FTIR-ATR) of Colombian crude oils, using chemometric methods of analysis (partial least squares - PLS) the aim of this research was to develop alternative techniques to the vacuum distillation of crude ASTM D 5236 and ASTM D 7119 High Temperature Distillation (GC) and thus achieve quick, non-destructive and environmentally friendly analyzes, minimizing the amount of sample and eliminating the use of reagents in its preparation.
