Some agro-industrial wastes are currently untreated, resulting in an increase in greenhouse gas emissions. Therefore, in relation to the pollution generated by fossil fuels, the study of the obtained fuels from agro-industrial and forestry residues has been promoted. Rice is a basic product for several families in the world, and its residue is a component that has enormous potential in Colombia due to its consumption. The objective of the present study is to conduct an exergoeconomic evaluation of the production of fuel from rice husks as agro-industrial waste by means of the slow and fast pyrolysis process. Using simulators like Aspen Plus, the simulation of the two processes was carried up, implementing a rigorous kinetic model. The yield values were validated with data from the literature, obtaining values of 42.3% and 41.4% for slow and fast pyrolysis, respectively, for pyrolytic oil. The total investment cost of the process is 2146.45 kUSD. According to the thermodynamic parameters of the simulator, an exergy analysis was conducted for the two processes. Overall exergy percentages of 73.84% and 78.19% were obtained for the slow and fast pyrolysis, respectively. The economic and exergy analysis was coupled to implement a specific exergy costing. The exergoeconomics factors obtained values of 72.21% and 76.78%, for the slow and fast pyrolysis reactors, respectively. The contribution of the present research is related to the rigorous kinetic model, in addition to its implementation in slow pyrolysis, involved in the exergoeconomic study of biomass pyrolysis processes.

稻壳残渣热解工艺生产燃料的运行经济评价

一些农工业废物目前未经处理，导致温室气体排放增加。因此，针对化石燃料产生的污染，从农工业和林业残留物中获取燃料的研究得到了推动。大米是世界上许多家庭的基本产品，其残留物是哥伦比亚因其消费而具有巨大潜力的组成部分。本研究的目的是通过慢速和快速热解过程对作为农业工业废物的稻壳生产燃料进行能源经济学评估。使用Aspen Plus等模拟器对这两个过程进行了模拟，实现了严格的动力学模型。利用文献数据验证了产率值，对于热解油，慢热解和快速热解的产率值分别为 42.3% 和 41.4%。该工艺总投资成本为2146.45 kUSD。根据模拟器的热力学参数，对两个过程进行了火用分析。慢热解和快速热解的总火用百分比分别为 73.84% 和 78.19%。经济分析和火用分析相结合以实施特定的火用成本计算。对于慢热解反应器和快速热解反应器，热经济因素的值分别为 72.21% 和 76.78%。本研究的贡献与严格的动力学模型有关，除了在缓慢热解中的实施之外，还涉及生物质热解过程的能量经济学研究。
