Unsolved accidents in fuel storage tanks : Resolution methodology by mathematical modeling under systemic appproach.
Supervisor(es): Robledo, Franco
Resumen:
Storage of mixtures of heavy hydrocarbon fuels with lighter components is a worldwide necessity because of their use for the construction of roads (asphalt diluted), the energy for industrial production (furnaces, boilers, electrical generators) and power for international transportation by ship of huge amounts of goods (big size internal combustion engines). This allows the development of a number of activities, provides the support for the production of goods and services worldwide, although its contribution appears invisible to the life as we know and for the world surrounding us as we perceive it. For its use, the heavy hydrocarbon fuels need to be handled, stored, transported, and transferred. All this operations have high risk of explosion. This thesis focuses on the explosions inside heavy fuel storage tanks. Particularly those that occurred long ago and have not had a full explanation. In this Thesis a generic methodology for determining hazardous atmospheres inside fuel tanks has been set, the modeling the combustion process inside the tank from the ignition in the presence of a spark or flame in the vicinity of an opening of the tank, and the consequences of this combustion ( resulting in a possible explosion ) on persons in the vicinity of the tank. This job was done in the expectative of be making a contribution to the investigation of such kind of unsolved accidents.
Las mezclas basadas en hidrocarburos pesados con componentes más livianos se utilizan en la construcción de carreteras (diluido asfáltico), en la energía para la producción industrial (hornos, calderas, generadores eléctricos) y en la generación de potencia de accionamiento para el transporte internacional por barco de enormes cantidades de bienes (motores de combustión interna de gran porte). Esto permite el desarrollo de una serie de actividades, ofrece el apoyo a la producción de bienes y servicios a nivel mundial, aunque su contribución aparece invisible para el mundo que nos rodea tal como lo percibimos. Para su uso, los combustibles de hidrocarburos pesados se manipulan, almacenan, transportan y transfieren. Todas estas operaciones tienen un alto riesgo de explosión. Esta tesis se centra en las explosiones dentro de los tanques de almacenamiento de combustible pesado. Particularmente los que ocurrieron hace mucho tiempo y no han tenido una explicación completa. En la misma se ha establecido una metodología genérica para la determinación de las atmósferas explosivas en el interior de tanques de combustible, el modelado del proceso de combustión en su interior a partir de la ignición ante la presencia de una chispa o llama en el entorno de una abertura del tanque, así como las consecuencias de esta combustión (derivando en una posible explosión) sobre las personas en el entorno del tanque. Este trabajo fue realizado con la expectativa de hacer una contribución a la investigación de este tipo de accidentes no resueltos.
