description In this investigation, a heavy crude oil ultrasonic treatment with the use of selected thermal initiators was evaluated in order to upgrade the heavy crude oil transportation properties and fractional composition through the cavitation energy generated by the system. The proposed treatment was conducted in two main steps. The first one involved the ultrasonic preparation and stability evaluation of heavy crude oil-in-water emulsions to generate high uniformity in their droplet size distribution and viscosity reductions in comparison with the base heavy crude oil, which were employed as the treatment medium for the use of persulfate initiators in the petroleum upgrading process. The main results of this step showed viscosity reductions up to 98% (500s-1 25°C) in comparison with the base heavy crude oil, droplet diameters of 4μm and volumetric stabilities up to 90% over 10 days for the emulsions (60/40) (O/W) prepared with concentrations of 2.5% of the surfactant merpol HCS, using ultrasonic amplitudes and induction times up to 70% and 12min, respectively, that leads to an energy consumption of 574.6 kJ per kg of processed crude oil. After the definition of the treatment medium, the properties of the crude oil, such as viscosity, residue, distillates and asphaltene content, were measured after several ultrasonic treatments (ultrasonic induction times and amplitude of 5 to 30min and 80%, respectively) at 60°C and atmospheric pressure, with the use of the initiators potassium persulfate and ammonium persulfate, the chain transfer agent n-dodecyl mercaptan and the hydrogen donors cyclohexane and decahydronaphthalene in order to identify possible upgrading changes in the crude oil. The main results of this study showed that despite of the slight changes generated in the distillates fraction by the ultrasonic treatments, it is possible to achieve high viscosity, asphaltene and coke reductions up to 65%, 42% and 37%, respectively, for the treated crude oils with the initiator potassium persulphate 0.5wt.%) and the hydrogen donor decahydronaphthalene (5.0wt.%) at ultrasonic induction times of 5min (energy consumption of 259.9 kJ per kg of crude oil), which shows the potential of the technology in transportation and processing applications of heavy crude oils.

La evaluación de la metodología de tratamiento se dividió en dos etapas principales. La primera consistió en la preparación y evaluación de la estabilidad de emulsiones de crudo-en-agua con ultrasonido, donde se buscó generar uniformidad en la distribución de diámetro de gota y reducciones de viscosidad respecto al crudo de estudio, que permitieran la incorporación de iniciadores radicalarios hidrosolubles de tipo persulfato en el medio para evaluar su desempeño en el mejoramiento del petróleo; los principales resultados de esta etapa, permitieron obtener emulsiones con reducciones de viscosidad de hasta un 98% (500s-1 25°C) respecto al crudo original, diámetros de gota promedio del orden de 4μm y estabilidades volumétricas del 90% por más de 10 días para emulsiones (60/40) (O/W) preparadas con el surfactante merpol HCS a concentraciones de 2.5%v/v, utilizando amplitudes sonoras del 70% y tiempos totales de exposición ultrasónica de 12min, equivalente a un consumo energético de 574.6 kJ por kg de crudo procesado. Posterior a la definición del medio de tratamiento, las propiedades del crudo de estudio tales como su viscosidad, contenido de residuo y destilables por termogravimetría, y contenido de asfaltenos, entre otros, fueron evaluados tras ser sometido a exposiciones sonoras entre 5 a 30min (80% de amplitud), a 60°C y presión atmosférica, incorporando los iniciadores persulfato de potasio y persulfato de amonio, el agente de transferencia de cadena n-dodecil mercaptano y los donores de hidrógeno ciclohexano y decahidronaftaleno al medio, en búsqueda de índices de mejoramiento. Los resultados principales de esta etapa permitieron establecer que, si bien solo se evidencian cambios leves en la fracción destilable del crudo a partir de los sistemas de tratamiento evaluados, es posible alcanzar reducciones de viscosidad, asfaltenos y coque de hasta un 65%, 42% y 37%, respectivamente, para crudos tratados con el iniciador persulfato de potasio (0.5%p/p) y el donor de hidrógeno decahidronaftaleno (5.0%p/p) a tiempos de exposición sonora de 5min, (consumo energético de 259.9kJ por kg de crudo procesado), que demuestra el potencial de la implementación de la tecnología tanto en posibles aplicaciones de transporte como en la reducción de fracciones pesadas del petróleo.Maestría243application/pdfspa620 - Ingeniería y operaciones afines660 - Ingeniería químicaheavy crude oil upgradingultrasonic treatmentcrude oil-in-water emulsionsinitiatorsasphaltenescokeviscositymejoramiento de crudos pesadostratamiento ultrasónicoemulsiones de crudo-en-aguainiciadoresasfaltenoscoqueviscosidadTratamiento de crudos pesados por sonicación con el uso de iniciadores radicalariosDocumento de trabajoinfo:eu-repo/semantics/workingPaperinfo:eu-repo/semantics/acceptedVersionhttp://purl.org/coar/resource_type/c_8042Texthttp://purl.org/redcol/resource_type/WPBogotá - Ingeniería - Maestría en Ingeniería - Ingeniería QuímicaUniversidad Nacional de Colombia - Sede BogotáAbismaı̈l B. et al.
