Simulação in silico da produção de biogás em biodigestores em série utilizando o software octave

Abstract

The main objective of this study was to address biogas production and explore the use of computational simulation as an analytical tool. The research focuses on evaluating the efficiency of different substrates and operational parameters in biodigester systems for biogas generation, aided by the Octave software, a mathematical programming language, and development environment. The study analyzed biomasses that are widely found in the Amazon biome: cocoa, acai, and coconut, comparing two production approaches: single-phase and multi-phase. The results revealed that the multi-phase system exhibited superior performance. For cocoa biomass, a maximum biogas production of 776.56 mL/gVSad was achieved. In the case of acai residues, a notably higher yield of 834.4 mL/gVSad was observed. As for coconut residues, the production reached 376.9 mL/gVSad. These findings underscore the efficiency of the multi-phase approach compared to the single-phase, highlighting its potential to maximize biogas production. Moreover, the utilization of organic waste as a biogas source contributes to waste reduction and clean energy generation, emerging as a viable and sustainable alternative in the realm of renewable energy production.
