Abstract

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.

利用猪粪产生的沼气作能源用途的技术选择评估。

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

期刊介绍： Founded in 1926, DYNA is one of the journal of general engineering most influential and prestigious in the world, as it recognizes Clarivate Analytics. Included in Science Citation Index Expanded, its impact factor is published every year in Journal Citations Reports (JCR). It is the Official Body for Science and Technology of the Spanish Federation of Regional Associations of Engineers (FAIIE). Scientific journal agreed with AEIM (Spanish Association of Mechanical Engineering) In character Scientific-technical, it is the most appropriate way for communication between Multidisciplinary Engineers and for expressing their ideas and experience. DYNA publishes 6 issues per year: January, March, May, July, September and November.
