The dataset presented in this article was collected in a laboratory flow circuit, which was designed to investigate high-viscosity flows. The data set is composed of 1200 s (equivalent to 12,000 samples) of mass flow and pressure measurements taken at five points along the pipeline. The first 300 s were recorded when the flow in the loop was composed only of glycerol. The remaining data were acquired when the flow was composed of a water–glycerol mixture. During the data acquisition, two extractions were produced. The research reported in [1] uses 160 s of the data provided here. This article explains in detail the experimental set-up and the principal instruments used for obtaining the dataset. The dataset is in the form of seven columns: Time, Mass Flow, Pressure 1, Pressure 2, Pressure 3, Pressure 4, Pressure 5, in supplementary Excel and Matlab files.

Control predictivo-cooperativo para operar una red de bombas centrífugas en un sistema serial de poliductos RESUMENLos sistemas de ductos brindan una conexión entre puertos, campos petrolíferos, refinerías y mercados de consumo. Los productos refinados como gasolinas, diésel, turbo-combustible, queroseno, entre otros, son transportados a través de una misma tubería. De esta forma se evitan costos adicionales de varias tuberías dedicadas a productos específicos. Este modo de transporte presenta el problema de la mezcla o contaminación entre productos, lo que incrementa los costos de operación. En este sentido, esta investigación presenta el problema de modelamiento y simulación de ductos utilizados para el transporte de diferentes clases de fluidos. Tal problema es solucionado teniendo en cuenta la presión, velocidad del medio y la densidad del fluido. Se considera un modelo matemático para predecir la cantidad de contaminación entre productos y se presenta el caso de varios tramos de tubería unidos por un modelo algebraico de bomba centrífuga. Con base en lo anterior, se diseña una estrategia de control predictivo teniendo en cuenta la optimización con subprocesos vecinos para coordinar los controles locales en las estaciones de bombeo y así lograr un rendimiento global en los niveles de contaminación. Finalmente, los resultados obtenidos confirman la eficiencia de la estrategia de control predictivo-cooperativo aplicada a una red de bombas centrífugas en un sistema serial de poliductos.Palabras clave: Poliductos, control predictivo, hidrocarburos, bombas centrífugas, interfase. , diesel, jet fuel, kerosene, etc., are ABSTRACT Pipeline systems provide a connection between ports, oil fields, refineries and consumer markets.

In this study, a novel experimental approach for the optimal selection of an actuator-based control strategy is presented. The proposed approach is a two-stage method: first, a two-level factorial experiment design with n factors (2n) was applied to compare different control schemes. Schemes comparison was carried out in terms of energy consumption and closed-loop performance. For the best relative scheme, a Central Composite Face-centered (CCF) design was completed obtaining the controller parameters that optimize the performance in terms of the Integral Absolute Error (IAE) while operating in a region of low energy consumption. The proposed approach was experimentally tested using real data obtained from a laboratory prototype plant. Some experimental tests illustrating the suitability of our method are shown at the end of this article.
