Se realizó una compilación y depuración de información operativa y en paralelo se llevó a cabo una contextualización bibliográfica basada en artículos relacionados. Posteriormente, se identificaron tres factores que impactan sobre la eficiencia del proceso: el desgaste del aislamiento térmico y/o las paredes del equipo, la temperatura y el flujo de la corriente de aire alimentada al sistema. Teniendo en cuenta lo anterior, se establecieron como opciones técnicas de mejora: intervenir el aislamiento térmico; realizar adecuaciones que permitieran ajustar el flujo de aire alimentado e instalar un sistema de calentamiento del aire. Posteriormente, se elaboró un modelo con las condiciones del proceso haciendo uso del software de simulación Aspen HYSYS® que permitió analizar el impacto de las alternativas sobre el sistema para así obtener evidencia de la repercusión de cada alternativa sobre el proceso. Para la primera alternativa se estima un ahorro entre 27 103,44 USD y 51 309,07 USD por año, para la segunda entre 56 856,52 y 73 049,23 USD por año y para la tercera entre 20 899,59 USD y 71 064,14 USD por año.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract This technical study consists of an operational analysis of two direct fired heaters in order to identify possible factors impacting their efficiency. Furthermore, possible improvements were raised based on articles and academic information related to these machines in order to increase their efficiency and decrease their gas consumption. Two sources of information were used: the academic one and the data provided by the company. Then, they were filtered to choose the most important of them and raise the alternatives. Three factors that impact the efficiency were identified; wear of the thermal isolation and/or their walls, the temperature and the flux of the air that is used in the system. Based on the filtered information, three alternatives were raised: check and fix the thermal isolation, adjust the air flux and install a pre-heating system to increase the temperature of the air. Subsequently, a simulation of the process was made on Aspen HYSYS ® to analyze the impact of the alternatives on the efficiency. Finally, evidence of the impact on gas consumption was obtained. The first alternative could save between $27,103.44/y and $ 51,309.07/y, the second between $ 56,856.52 and $ 73,049.23/y and the third one between $20,899.59/y and $71,064.14/y.]]></p></abstract>
<abstract abstract-type="short" xml:lang="pt"><p><![CDATA[Resumo Este estudo técnico foi feito através de uma análise operacional de dois aquecedores de queima direta, a fim de identificar possíveis fatores que impactam sua eficiência. Além disso, possíveis melhorias foram levantadas com base em artigos e informações acadêmicas relacionadas a estas máquinas, de modo a aumentar sua eficiência e diminuir seu consumo de gás. Foram utilizadas duas fontes de informação: a acadêmica e os dados fornecidos pela empresa. Em seguida, as mais importantes foram selecionadas para suscitar alternativas. Três fatores que impactam a eficiência foram identificados: o desgaste do isolamento térmico e/ou de suas paredes, a temperatura e o fluxo de ar que é utilizado no sistema. Com base nas informações selecionadas, três alternativas foram apontadas: verificar e corrigir o isolamento térmico, ajustar o fluxo de ar e instalar um sistema de pré-aquecimento para aumentar a temperatura do ar. Posteriormente, uma simulação do processo foi feita no Aspen HYSYS ® para analisar o impacto das alternativas sobre a eficiência. Finalmente, foram obtidas evidências do impacto sobre o consumo de gás. A primeira alternativa poderia economizar entre $ 27 103,44/ano e $ 51 309,07/ano, a segunda entre $ 56 856,52 e $ 73 049,23/ano e a terceira entre $20 899,59/ano e $ 71 064,14/ano.]]></p></abstract>
