Construcción de un modelo predictivo para la determinación de la cantidad de agua en crudos mediante el uso de espectroscopia de infrarrojo medio y quimiometría

Abstract

This work describes the methodology used to construct a predictive model that will allow the measurement of the amount of water in Colombian crude using infrared spectroscopy in total attenuated reflectance mode (ATR) and chemometric techniques for data processing (PLS and PCA). The results obtained in this study allowed us to establish that the use of the chemometric techniques PLS and PCA and infrared spectroscopy in the mode of attenuated total reflectance (ATR) are viable in the construction of chemometric models for the quantification of water in Colombian crudes. These models can be postulated for laboratory use, offering the advantage of rapid analysis and a small amount of sample compared to the techniques currently used.
