Identificación de aspectos técnicos para reducir el contenido de sal y el porcentaje de agua y sedimentos en un proceso de desalado de crudo, mediante análisis estadístico multivariado

In this project, an analysis of the operating conditions of the crude oil desalination process was carried out by means of multivariante statistical analysis. The statistical analysis performed had the ability to identify possible operational changes, taking into account the influence of process variables such as operating temperatures, dilution water ratio, differential differences generated by the water-oil mixing valve on the removal of salt and the percentage of water and sediments (% BS&W) in the crude. Based on the historical data analyzed, describe the behavior of the desalination process variables in a refinery. This analysis was carried out through the statistical technique of Multivariate Analysis and Multiple Linear Regression, using Statgraphics 18® software. For the determination of correlations, the mathematical model of linear prediction and finally formulation of the possible adjustments to achieve the reduction of salt content and the percentage of water and sediments (% BS&W). In this way, it is modified to identify that for the reduction of salt content and the percentage of water and sediments (%BS&W), the variables that most influence this process are pressure differential in the mixing valve and the operating temperature of the desalination plants, therefore, the proposed recommendations are aimed at the adjustments of these variables since, according to the statistical results affected, the desalination process is affected.
