| description |
Thixotropic fluids represent an operational challenge for transportation techniques. A Colombian heavy crude oil that exhibits non-Newtonian behavior is studied and thixotropy is observed. A wide range of novel rheological experiments are used to evaluate this unusual characteristic. This behavior can affect flow assurance, given the drastic changes in kinematic viscosity modifying the required pumping strategies. By implementing different techniques such as loop hysteresis and shear peek hold experiments, thixotropy is assessed. Results show that thixotropy is less dominant at higher temperatures (~80?) highly dependent on testing times and shear rate. Additionally, it is shown that some traditional tests are not suitable for thixotropy analysis due to interference with viscous heating and that resting periods and stress growth vary depending on the temperature. Finally, it is shown that the amount of asphaltenes in solution significantly affect the degree of thixotropy of crude oil. |

Se estudia un crudo pesado colombiano que exhibe un comportamiento no newtoniano y se observa la tixotropía. Se utiliza una amplia gama de nuevos experimentos reológicos para evaluar esta característica inusual. Este comportamiento puede afectar la garantía de flujo, dados los cambios drásticos en la viscosidad cinemática que modifican las estrategias de bombeo requeridas. Al implementar diferentes técnicas, como la histéresis de bucle y los experimentos de retención de cizallamiento, se evalúa la tixotropía. Los resultados muestran que la tixotropía es menos dominante a temperaturas más altas (~ 80) y altamente dependiente de los tiempos de prueba y la velocidad de corte. Además, se muestra que algunas pruebas tradicionales no son adecuadas para el análisis de tixotropía debido a la interferencia con el calentamiento viscoso y que los períodos de reposo y el crecimiento del estrés varían según la temperatura. Finalmente, se muestra que la cantidad de asfaltenos en solución afecta significativamente el grado de tixotropía del petróleo crudo."--Tomado del Formato de Documento de Grado.Magíster en Ingeniería QuímicaMaestría29 hojasapplication/pdfengUniandesMaestría en Ingeniería QuímicaFacultad de IngenieríaDepartamento de Ingeniería Química y de Alimentosinstname:Universidad de los Andesreponame:Repositorio Institucional SénecaUnusual thixotropic behavior of a Colombian heavy crude oil.
