BIO-PCI, Inyección de carbón vegetal en Altos Hornos: Estado del arte y perspectivas económicas

Abstract

La inyección de carbón vegetal por toberas en Altos Hornos, aqui denominada Bio-PCI, se presenta como una forma atractiva y realista de reducir significativamente las emisiones de CO2 generadas durante la producción de arrabio. En esta contribución se presenta un resumen de los fundamentos tecnológicos, los beneficios y las limitaciones de la incorporación de la tecnología del Bio-PCI. Adicionalmente se exponen los retos económicos que enfrentan los combustibles renovables a los fósiles, con especial interés en los principales costos de producción del carbón vegetal. En este sentido se plantea una pregunta estratégica: ¿puede la biomasa residual impulsar el desarrollo de la Bio-PCI?. Nuestro análisis conlleva a concluir que la utilización de biomasa residual (residuos forestales y agrícolas) puede reducir sensiblemente el costo del carbón vegetal entre 120-180 USD/t en comparación con biomasa primaria, incrementando su competitividad frente al carbón mineral.
