Simulação da produção de combustível de aviação sustentável (SAF) pela rota de álcool para querosene (ATJ) com o programa COCO Simulator

Abstract

The aviation transportation industry continues to expand, resulting in a significant increase in global kerosene consumption. As an alternative to mitigate the emissions and environmental impacts associated with this growth, sustainable methods for producing green aviation kerosene have been developed. In this context, this work analyzes the application of the CAPE-OPEN to CAPE-OPEN (COCO) simulator to model the production route of green kerosene from alcohol, using operational data from a plant with an annual capacity of 6,000 barrels, based on the study by Teixeira (2024). Additionally, an economic analysis of the current green kerosene landscape in Brazil is presented, considering the different production routes already established and certified, their limitations, and the market opportunities they offer. The results indicate that the simulator is suitable for future studies; however, there are limitations related to the ChemSep database integrated into the program. In some cases, an extensive search for thermodynamic property data is required for substances not included in the downloadable database. Regarding the established production routes, they appear technically promising but are not yet commercially viable in the current context, highlighting the need for continued research and government economic incentives.
