Ingeniería de Sistemas Químicos y de Procesos

¡Bienvenido a la página del grupo de Ingeniería de Sistemas Químicos y de Procesos!

Nuestro grupo está formado por investigadores y docentes que actúan en el área de la Ingeniería de Sistemas de Procesos (Process Systems Engineering, PSE). La PSE es un campo dentro de la Ingeniería Química que busca sistematizar el diseño, análisis, operación y toma de decisiones en las diferentes etapas de los procesos que involucran transformaciones químicas y/o físicas y/o biológicas. El foco está en cómo los distintos componentes interaccionan entre sí y cómo estas interacciones contribuyen al comportamiento del sistema como un "todo".

La PSE es una disciplina integradora que combina áreas básicas de la ingeniería química (transporte de momento, calor y masa, termodinámica, diseño de reactores, etc.) con elementos de matemática y programación, para abordar problemas de:

Síntesis, diseño e integración de procesos
Modelado y simulación de procesos
Optimización de procesos (programación lineal, no lineal y entera mixta, optimización dinámica, optimización global)
Estimación de parámetros
Análisis de incertidumbre, sensibilidad y toma de decisiones basadas en información experimental (datos)
Planificación y schedulling de operaciones

Dentro de las aplicaciones de la PSE nos especializamos en:

Bio-refinerías: análisis y diseño de procesos de conversión de biomasa en combustibles, químicos y materiales de alto valor agregado
Procesos de secado en la Industria Láctea
Análisis de Tambos
