| description |
Drag reduction is becoming one of the main points of interest for researchers attempting to increase transport efficiency for all kinds of fluids, with crude oil being one of the main goals due to its high viscosity and economic relevance. This study tries to establish a consistent methodology to evaluate drag reduction in rheometers, using heavy crude oil as the focus. Dilutions using xylene were performed to reduce the viscosity of the system allowing turbulence inside a Couette cell to be achieved. On the other hand, drag reduction results show a significant change in viscosity and torque profiles when polyisobutylene (PIB) with molecular weight of 10^6 g/mol is added in concentrations between 2000-30000 ppm to the oil samples. Whereas using carboxymethyl cellulose (CMC) with a molecular weight of 9000 g/mol as a water-soluble polymer at 1000 ppm makes tests non-replicable, due to the presence of two distinct phases inside the rheometer. Initial degradation studies were carried out, managing to reassure the capabilities of PIB to resist mechanical degradation, proving to be a suitable drag reducing agent with the preliminary rheometer tests performed. A reproducible methodology, to study oil soluble drag reducing agents and a normalization approach on how to treat rheometric data as a tool for the evaluation of the drag reduction phenomenon is presented. |

Este estudio trata de establecer una metodología consistente para evaluar la reducción de drag en reómetros, utilizando como foco crudo pesado. Se realizaron diluciones con xileno para reducir la viscosidad del sistema permitiendo alcanzar la turbulencia dentro de una celda de Couette. Por otro lado, los resultados los aditivos muestran un cambio significativo en los perfiles de viscosidad y torque cuando se añade poliisobutileno (PIB) con un peso molecular de 10^6 g/mol en concentraciones entre 2000-30000 ppm a las muestras de petróleo. Mientras que el uso de carboximetilcelulosa (CMC) con un peso molecular de 9000 g/mol como polímero soluble en agua a 1000 ppm hace que las pruebas no sean reproducibles, debido a la presencia de dos fases distintas dentro del reómetro. Se realizaron los estudios preliminares de degradación mecanica, logrando reafirmar las capacidades del PIB para resistir la degradación, demostrando ser un agente reductor de drag adecuado con las pruebas realizadas. Se presenta una metodología reproducible para el estudio de agentes reductores de drag solubles en aceite y un enfoque de normalización sobre cómo tratar los datos reométricos como herramienta para la evaluación del fenómeno de reducción de arrastre.Magíster en Ingeniería QuímicaMaestría31 páginasapplication/pdfspaUniversidad de los AndesMaestría en Ingeniería QuímicaFacultad de IngenieríaDepartamento de Ingeniería Química y de AlimentosRheology of drag reducing agents on crude oil systemsTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMDrag reductionPolymersRheologyTurbulent flowDegradationCrude oilIngeniería201512818Publicationhttps://scholar.google.es/citations?user=KRpunCoAAAAJvirtual::8804-10000-0001-8810-9526virtual::8804-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000069593virtual::8804-1ce1c2534-6d8a-4981-8def-52f4d33132favirtual::8804-1ce1c2534-6d8a-4981-8def-52f4d33132favirtual::8804-1ORIGINAL25832.pdfapplication/pdf3935430https://repositorio.uniandes.edu.co/bitstreams/96f4dac0-ee8a-4589-b9ab-b2cc0a37a812/download4e7de10f9ad1b46bedf6d29c14ad796cMD51THUMBNAIL25832.pdf.jpg25832.pdf.jpgIM Thumbnailimage/jpeg19618https://repositorio.uniandes.edu.co/bitstreams/41167db2-cbd1-4812-9601-dab130d74810/download856a481dd5bca1c0163d3529828a340cMD53TEXT25832.pdf.txt25832.pdf.txtExtracted texttext/plain49015https://repositorio.uniandes.edu.co/bitstreams/071ae56e-a912-4e9d-b273-27c8b6d8807d/download4091fc226b9b341b208c6cf70949d367MD521992/55094oai:repositorio.uniandes.edu.co:1992/550942024-03-13 13:46:26.864http://creativecommons.org/licenses/by-nc-nd/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |
