    La utilizaci贸n de nuevos m茅todos de control es una de las 谩reas de mayor inter茅s en la industria en los 煤ltimos a帽os ya que permite un mejor aprovechamiento de los recursos y por tanto se convierte en un factor importante en la disminuci贸n de costos asociados con el reproceso y el gasto innecesario de materia prima. En la presente investigaci贸n se eval煤a el desempe帽o de un controlador basado en l贸gica difusa implementado sobre un sistema Mezclador-Reactor, El controlador por l贸gica difusa (FLC) es analizado para el caso multivariable en distintas condiciones de operaci贸n y su desempe帽o se compara con el logrado mediante la implementaci贸n de un controlador cl谩sico PID para desviaciones del 10% de los valores de estado estable. En los resultados se puede apreciar que el controlador basado en l贸gica difusa FLC presenta un comportamiento adecuado mejorando en hasta un 30% al control clasico, esto sumado a la ventaja de poder incluir la experiencia que se tiene sobre el proceso en las acciones que son tomadas por la estrategia para mantener el proceso en los rangos de operaci贸n deseados.Abstract: The use of new methods of control is one of greatest interest in the industry in recent years because it makes better use of resources and thus becomes an important factor in reducing costs associated with reprocessing and unnecessary use of raw materials. This research has the goal to evaluate the behavior of a fuzzy logic controller implemented on a combined mixer-reactor system. The fuzzy logic controller (FLC) is analyzed for the multivariable case in different operating conditions and its performance is compared with obtain through the implementation of a classical PID controller for deviations of 10% of the steady-state. The results show that the fuzzy logic controller (FLC) has a proper performance and improve in about 20% the classical control, this combined with the advantage of being able to include experience on process in actions taken by the strategy to keep the process in desired operation ranges

    18 p谩ginasLatin America is starting its energy transition. In Colombia, with its abundant natural resources and fossil fuel reserves, hydrogen (H2 ) could play a key role. This contribution analyzes the potential of blue H2 production in Colombia as a possible driver of the H2 economy. The study assesses the natural resources available to produce blue H2 in the context of the recently launched National Hydrogen Roadmap. Results indicate that there is great potential for low-emission blue H2 production in Colombia using coal as feedstock. Such potential, besides allowing a more sustainable use of non-renewable resources, would pave the way for green H2 deployment in Colombia. Blue H2 production from coal could range from 700 to 8000 ktH2 /year by 2050 under conservative and ambitious scenarios, respectively, which could supply up to 1.5% of the global H2 demand by 2050. However, while feedstock availability is promising for blue H2 production, carbon dioxide (CO2 ) capture capacities and investment costs could limit this potential in Colombia. Indeed, results of this work indicate that capture capacities of 15 to 180 MtCO2 /year (conservative and ambitious scenarios) need to be developed by 2050, and that the required investment for H2 deployment would be above that initially envisioned by the government. Further studies on carbon capture, utilization and storage capacity, implementation of a clear public policy, and a more detailed hydrogen strategy for the inclusion of blue H2 in the energy mix are required for establishing a low-emission H2 economy in the country.Am茅rica Latina est谩 iniciando su transici贸n energ茅tica. En Colombia, con sus abundantes recursos naturales recursos naturales y reservas de combustibles f贸siles, hidr贸geno (H2 ) podr铆a desempe帽ar un papel clave. Esta contribuci贸n analiza el potencial de la producci贸n de H2 azul en Colombia como posible impulsor de la econom铆a del H2. El estudio eval煤a los recursos naturales disponibles para producir H2 azul en el contexto del reciente lanzamiento Hoja de Ruta Nacional del Hidr贸geno. Los resultados indican que existe un gran potencial para el H2 azul de bajas emisiones producci贸n en Colombia utilizando carb贸n como materia prima. Tal potencial, adem谩s de permitir una vida m谩s sostenible uso de recursos no renovables, allanar铆a el camino para el despliegue del H2 verde en Colombia. Azul La producci贸n de H2 a partir del carb贸n podr铆a oscilar entre 700 y 8.000 ktH2 /a帽o para 2050 bajo un r茅gimen conservador y escenarios ambiciosos, respectivamente, que podr铆an abastecer hasta el 1,5% de la demanda mundial de H2 para 2050. Sin embargo, si bien la disponibilidad de materia prima es prometedora para la producci贸n de H2 azul, el di贸xido de carbono (CO2 ) las capacidades de captura y los costos de inversi贸n podr铆an limitar este potencial en Colombia. De hecho, los resultados de este Los trabajos indican que se pueden capturar capacidades de 15 a 180 MtCO2. /a帽o (escenarios conservadores y ambiciosos) deben desarrollarse para 2050, y que la inversi贸n requerida para el despliegue del H2 ser铆a superior lo previsto inicialmente por el gobierno. Estudios adicionales sobre captura, utilizaci贸n y capacidad de almacenamiento, implementaci贸n de una pol铆tica p煤blica clara y una estrategia de hidr贸geno m谩s detallada para la inclusi贸n de H2 azul en la combinaci贸n energ茅tica son necesarios para establecer una econom铆a de H2 con bajas emisiones en el pa铆s
