Evaluación Ambiental e integración energética de una planta para producción de bioetanol a partir de residuos de arroz
Abstract
Resumen: En este trabajo se presenta una evaluación ambiental y de integración energética de una planta para producción de bioetanol a partir de residuos de arroz. Se simuló el proceso a partir de datos y reportes de condiciones de operación. Se utilizó el software de ingeniería de procesos ASPEN PLUS. Los datos de simulación permitieron realizar análisis pinch para determinar el potencial de integración energética de la planta. Se propuso una red de intercambiadores de calor para la reducción de suministro energético por servicios industriales para calentamiento y enfriamiento. Finalmente, se realizó un análisis ambiental del proceso integrado y el caso base, utilizando la herramienta WAR GUI, para determinar los PEI (potenciales impactos ambientales) del proceso y establecer una comparación entre el caso base y el integrado.
Palabras clave: Bioetanol, ASPEN PLUS, integración energética, análisis ambiental, WAR GUI
Abstract: This paper presents an environmental assessment and energy integration of a plant for
the production of bioethanol from rice residues. The process was simulated from data reports of
operating conditions in the literature. ASPEN PLUS process engineering software was used. The
simulation data allowed to develop pinch analysis to determine the energy integration potential of
the plant. A network of heat exchangers was proposed for the reduction of energy supply by
industrial services for heating and cooling. Finally, an environmental analysis of the integrated
process and the base case were performed using the WAR GUI tool to determine the potential
environmental impacts of the process and to establish a comparison between the integrated and non-integrated case
Keywords: Bioethanol, ASPEN PLUS, energy integration, environmental analysis, WAR GUI.
