El alto grado de automatización adquirido en las plantas químicas durante las últimas décadas hace que las tareas de supervisión sean ahora más complejas y delicadas. Esta supervisión requiere de sistemas y herramientas ...
Plant safety is the most important concern of chemical industries. Process faults can cause economic loses as well as human and environmental damages. Most of the operational faults are normally considered in the process ...
Els residus radioactius procedeixen de gairebé totes les activitats (indústria nuclear i no nuclear, investigació, activitats militars, aplicacions mèdiques) que impliquen la manipulació de materials radioactius. Existeix ...
El desenvolupament de processos termoquímics destinats a la valorització de materials lignocel·lulòsics (gasificació i piròlisi, principalment), tant pel que fa al disseny de reactors com pel que fa a l'establiment de les ...
Fire is the most common phenomenon that characterizes major accidents that take place in both industrial establishments and in the transport of dangerous goods by road and rail. The formation of a fireball, with or without ...
El treball presentat en aquesta tesi pretén contribuir a l'estudi mediambiental de la limitació de les emissions de components orgànics volàtils (VOCs), degudes a l'ús de dissolvents orgànics en determinades activitats i ...
Esta tesis se presenta como un conjunto de artículos (ya publicados en revistas internacionales, con la excepción del Artículo 6) precedidos por una serie de capítulos introductorios. 1. Introducción. Describe los puertos ...
This thesis presents, discusses and compares a set of methodologies and several appropriate combinations of them, to provide accurate estimation of process variables, either for steady-state or dynamic systems. <br/><br/>Firstly, ...
The photosynthesis is the process used by the plants and bacteria cells to convert the inorganic matter in organic thanks to the light energy. This process consist on several steps, being one of them the plastoquinone-9 ...
To extend the knowledge of complex distillation arrangements for the separation of ternary mixtures and make them closer to implementation in industry is the motivation of this thesis work. Some design, operation, and ...
En esta tesis se presenta un conjunto de metodologías que intentan facilitar la tarea de explotación de la información contenida en los datos históricos de proceso y como reaprovecharlos de modo de producir un impacto ...
Specialty chemicals industry relies on batch manufacturing, since it requires the frequent adaptation of production systems to market fluctuations. To be first in the market, batch industry requires decision-support systems ...
In the current environment of markets globalization and fierce competition, process industries must strive to remain competitive. In this sense, companies pursue decision integration among the different space and time ...
Identifying hazards is fundamental for ensuring the safe design and operation of a system in process plants and other facilities. Several techniques are available to identify hazardous situations, all of which require their ...
El modelo actual del consumo energético basado en la utilización de combustibles fósiles requiere un replanteamiento debido al agotamiento de éstos y a las emisiones de gases contaminantes que generan. La obtención de ...
The growing concern over environmental pollution in recent decades has placed increasing focus on research into the development of sustainable processes associated with the removal of contaminants in waters. Water is scarcer ...
This work facuses on the study of these processes on Ti02 and Ce02, respectively. Although the development of photocatalytic research with the use of semiconductor photocatalysts does not last longer than about 40 years, ...
En el campo de la cinética de la pirólisis de biomasa se han desarrollado numerosos trabajos de investigación que no acaban de resolver aspectos básicos del proceso. El análisis de resultados termogravimétricos aún requiere ...
Los materiales compuestos nanoestructurados son considerados una opción prometedora para la concepción de materiales multifuncionales. Sin embargo, la falta habitual de interacción entre los componentes orgánicos e ...
