Human being has been always thinking to apply renewable energy due to limited resources of energy. Therefore, alternative fuels have been chosen based on the following characteristics: environmental sustainability, being competitive with fossil fuels, technical justification, and easy production. In this research, various biodiesel production processes are simulated and technically analyzed using Aspen HYSYS. Then, the related flowsheets have been economically analyzed by Aspen Capital Cost Estimator (Icarus). Finally, the present net values have also been estimated by means of parameters such as the cost and sale values of vegetable oils, glycerol, NA₃PO₄, H₃PO_4, and biodiesel based on the interest rates. Considering these analyses, prediction procedures, equations of capital cost estimation, and net present value were developed. According to the analysis, the use of palm oils is more appropriate than other oils for biodiesel production because its ROR (36.01%) is higher than soybean oil (27.64%) and olive oil (3.39%). According to the calculated ROR values, palm oil and soybean oil have scored the highest rate of return, respectively.

不同植物油生产生物柴油的技术和经济评价

由于能源有限，人类一直在思考使用可再生能源。因此，已根据以下特征选择了替代燃料：环境可持续性，与化石燃料的竞争性，技术合理性以及易于生产。在这项研究中，使用Aspen HYSYS对各种生物柴油生产过程进行了模拟和技术分析。然后，相关流程已由Aspen资本成本估算器（Icarus）进行了经济分析。最后，目前的净值还可以通过诸如植物油，甘油，NA ₃ PO ₄，H ₃ PO ₄的成本和销售价值等参数进行估算。和生物柴油的利率。考虑到这些分析，开发了预测程序，资本成本估计方程和净现值。根据分析，棕榈油比其他油更适合用于生物柴油生产，因为其ROR（36.01％）高于大豆油（27.64％）和橄榄油（3.39％）。根据计算出的ROR值，棕榈油和大豆油分别获得了最高的回报率。
