摘要
这项工作整合了一个过程模拟，猪浆的厌氧消化和三种技术替代的沼气的能源利用。此外，还对古巴不同猪群情景下的能量产量和技术经济可行性进行了评价。采用Aspen Plus v12.0作为备选方案:蒸汽发生器、内燃机和余热锅炉。研究结果表明，能源效率在79%-85%之间，TIR在36%-43%之间，VAN在2578818.80美元-1975810.72美元之间，PRD在2.8至3.5年之间。研究发现，该项目的盈利能力对每个备选方案的猪群情况变化最为敏感，其中方案4的盈利能力最强。这项研究为农村地区使用这种可再生能源提供了重要见解，重点是环境的可持续性。关键词:沼气，能效，Aspen模型，经济分析
ASSESSMENT OF TECHNOLOGICAL OPTIONS FOR UTILIZING BIOGAS PRODUCED FROM SWINE WASTE FOR ENERGY PURPOSES.
This work integrated in a process simulation, the anaerobic digestion of swine slurry and three technological alternatives for the energetic use of biogas. In addition, the energy yield and technical-economic feasibility were evaluated under different swine population scenarios in Cuba. Aspen Plus v12.0 was used to incorporate the alternatives analyzed: steam generator, internal combustion engine and heat recovery boiler. The results of the study indicated energy efficiencies between 79%-85%, TIR between 36%-43%, VAN between 2578818.80$-1975810.72$, with a PRD between 2.8 and 3.5 years. The profitability of the project was found to be most sensitive to the variation in the scenarios of pig population per alternative, with scenario 4 being the most profitable. The study provides important insights into the use of this renewable energy sources in rural areas, with a focus on environmental sustainability. Key Words: Biogas, energy efficiency, Aspen modelling, economic analysis.
