Renewable energy sources are prospective solutions for addressing future energy needs arising from the ever-increasing population and dwindling petroleum reserves. Biobutanol is one of the most efficient biofuels for use as a mixture with motor vehicle fuels. Biobutanol is produced from the acetone-butanol-ethanol (ABE) fermentation process and is separated into the pure components via multicomponent distillation. Mathematical modelling of the continuous multicomponent distillation of ABE was carried herein out using an equilibrium-based model with the modified Hang-Wanke method in MATLAB R2020a programming language and compared with the simulation results using Aspen Plus V9. The variables of this study were the feed stage, number of trays, reflux ratio to butanol purity, butanol recovery, and energy load of the reboiler and condenser. Based on the simulation results, the operating conditions in columns 1 and 2 were recommended based on the butanol purity, recovery, and reboiler load; the recommended operating conditions for column 1 are as follows—feed stage: 4, reflux ratio: 4, number of trays: 20 trays, with a column efficiency of 55.43%. The recommended operating conditions for column 2 are as follows—feed stage: 2, reflux ratio: 0.4, number of trays: up to 10, with a column efficiency of 54.94%.

可再生能源是解决因人口不断增长和石油储量减少而产生的未来能源需求的前瞻性解决方案。生物丁醇是与机动车燃料混合使用的最有效的生物燃料之一。生物丁醇是从丙酮-丁醇-乙醇（ABE）发酵过程中产生的，并通过多组分蒸馏分离为纯组分。本文使用MATLAB R2020a编程语言中的改进的Hang-Wanke方法基于平衡的模型对ABE进行连续多组分蒸馏的数学模型，并与使用Aspen Plus V9的仿真结果进行了比较。这项研究的变量是进料阶段，塔板数，与丁醇纯度的回流比，丁醇回收率以及再沸器和冷凝器的能量负荷。根据模拟结果，根据丁醇的纯度，回收率和再沸器负荷，推荐了第1列和第2列中的操作条件。色谱柱1的推荐操作条件如下：进料阶段：4，回流比：4，塔板数：20个塔板，塔效率为55.43％。色谱柱2的推荐操作条件如下：进料阶段：2，回流比：0.4，塔板数：最多10个，色谱柱效率为54.94％。
