Sofán Germán, Stiven JavierArgumedo Berona, Germán ElíasMora Agámez, Manuel Enrique2021-09-282021-09-282021-09-24https://repositorio.unicordoba.edu.co/handle/ucordoba/4582The objective of this applicative monograph is to carry out an exergy analysis of steam generation through the gasification of industrial corn residues as working biomass; To achieve this objective, a characterization of the biomass was first carried out to determine the last and next analyzes, in order to obtain the chemical composition of the corn cob. Then a computational model was made in Aspen Plus® where the data of a syngas with a lower heating value (LHV) of 6.18 MJ/Nm3 were produced, which was later injected into a boiler for the generation of steam in the system. After this, an exergy analysis was carried out on the data obtained in the simulation, which showed that 14.37 kW are used in steam generation, and it was also determined that the exergetic efficiency of the system is 35%, largely part due to irreversibility’s and exergy destroyed.INTRODUCCIÓN
