description |
Asphaltenes have a predominant role in the interfacial behavior of crude oil. Fluid-fluid interfaces are ubiquitous in recovery, treatment, and transport processes for the crude oil industry having a determinant influence on their performance. Understanding different interfacial phenomena when asphaltenes are present is a critical challenge for efficiency and environmentally safe operations. This understanding represents a modern engineering challenge due to their complex molecular nature, the wide variety of chemical motifs, and dynamic functionalities. An alternative to address this complex challenge is the use of rationally designed molecules that serve as asphaltene model compounds reproducing the main features in terms of sorption and interfacial dynamics. The use of asphaltene model compounds, whose molecular characteristics are known, generates a solid framework to connect defined molecular structural characteristics with their interfacial properties. This approximation provides relevant insights to the comprehension of the interfacial activity of asphaltenes. Shedding light on such a complex system requires building a comprehensive view of the phenomena. Through the multi-scale approach presented here, isotropic and anisotropic interfacial deformations and dynamic structural visualization are coupled to construct connections at the molecular, microscopic, and millimetric scales to draw fundamental structure-properties relationships for natural and model asphaltenes at the decane-water and air-water interfaces. |

Las interfaces fluido-fluido son omnipresentes en los procesos de recuperación, tratamiento y transporte de la industria del petróleo y tienen una influencia determinante en su desempeño. Comprender los diferentes fenómenos interfaciales cuando hay asfaltenos es un desafío crítico para la eficiencia y las operaciones ambientalmente seguras. Esta comprensión representa un desafío para la ingeniería moderna debido a su compleja naturaleza molecular, la amplia variedad de estructuras químicas y funcionalidades dinámicas. Una alternativa para abordar este complejo desafío es el uso de moléculas diseñadas racionalmente que sirven como asfaltenos modelo que reproducen las principales características en términos de adsorción y dinámica interfacial. El uso de asfaltenos modelo, cuyas características moleculares son conocidas, genera un marco sólido para conectar las características estructurales de moléculas definidas con sus propiedades interfaciales. Esta aproximación proporciona conocimientos relevantes para la comprensión de la actividad interfacial de los asfaltenos. Arrojar luz sobre un sistema tan complejo requiere construir una visión integral de los fenómenos. A través del enfoque de multi-escala que se presenta aquí, las deformaciones interfaciales isotrópicas y anisotrópicas y la visualización estructural dinámica se acoplan para construir conexiones a escalas moleculares, microscópicas y milimétricas creando conexiones estructura-propiedades fundamentales para asfaltenos naturales y modelo en interfaces decano-agua y aire-agua.Doctor en IngenieríaDoctorado113 hojasapplication/pdfengUniversidad de los AndesDoctorado en IngenieríaFacultad de IngenieríaInterfacial behavior of natural and model asphaltenes : a multi-scale approachTrabajo de grado - Doctoradoinfo:eu-repo/semantics/doctoralThesishttp://purl.org/coar/resource_type/c_db06http://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TDAsfaltenoPrecipitación (Química)Ingeniería201711230PublicationTEXT23605.pdf.txt23605.pdf.txtExtracted texttext/plain253029https://repositorio.uniandes.edu.co/bitstreams/cb1107e5-8887-4585-a77f-5bb84810704c/download3b463472b4188dbc8ef790db60d71da4MD54THUMBNAIL23605.pdf.jpg23605.pdf.jpgIM Thumbnailimage/jpeg27887https://repositorio.uniandes.edu.co/bitstreams/34bfaf55-372e-4da5-9bac-698a5f5be4fd/downloaddab51ae5dbaff32c173253994c8ebcefMD55ORIGINAL23605.pdfapplication/pdf31815543https://repositorio.uniandes.edu.co/bitstreams/7419206a-fd51-4b7f-987b-9ffc17c5bc11/download6de00c8e76c19dedb7e35dadcb812d60MD511992/50844oai:repositorio.uniandes.edu.co:1992/508442024-08-26 15:17:16.792https://repositorio.uniandes.edu.co/static/pdf/aceptacion_uso_es.pdfopen.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co |
