Modelado de la viscosidad aparente de un petróleo crudo de 11°API con comportamiento no newtoniano

Abstract: La técnica más utilizada en el trasiego de crudos pesados para lograr valores adecuados de viscosidad radica en el calentamiento del fluido, mediante la que se mejoran sus propiedades de flujo. En este trabajo se expone el comportamiento de flujo y la influencia que ejerce la temperatura sobre las propiedades reológicas de un petróleo crudo pesado de 11º API. A partir del estudio reológico se demostró que el petróleo mantiene un comportamiento seudoplástico para variación de temperatura de 29 a 69,8 ºC. Para e… Show more

“…Pérez et al [ 9 ] conducted experimental tests of Newtonian and non-Newtonian fluids in the Couette viscometer and performed the respective statistical adjustments associated with the Carreu-Yasuda rheological model. In addition, Laurencio et al [ 10 ] obtained the rheological parameters of crude oil associated with the Ostwald de Waele pseudo-plastic model at various temperatures, indicating the importance of determining the apparent viscosity during the treatment and transportation of crude oil.…”
