CO₂ removal by the blended amine solution of piperazine (PZ) and methyldiethanolamine (MDEA) with the various molar concentration ratios in a rotating packed bed (RPB) was modelled using MATLAB linked to Aspen Plus. All the required correlations for the RPB in addition to the mass and energy balances were written in MATLAB while the demanded physical and transport properties were extracted from Aspen Plus. The similar operating conditions and compositions in the reported experiments were used to run the model by the two-film theory for mass transfer as steady state, while the impact of five different parameters on the CO₂ absorption efficiency was examined to validate the model. The modeling results are in good agreement with the experimental data for which the average absolute deviation is less than 7.0%. The process analysis revealed that rotational speed and PZ concentration have the most significant effects on CO₂ absorption efficiency.

使用连接到 Aspen Plus 的 MATLAB 对在旋转填充床 (RPB) 中通过具有各种摩尔浓度比的哌嗪 (PZ) 和甲基二乙醇胺 (MDEA) 的混合胺溶液去除CO ₂进行建模。除了质量和能量平衡之外，RPB 所需的所有相关性都在 MATLAB 中编写，而所需的物理和传输特性则从 Aspen Plus 中提取。报告实验中类似的操作条件和组成用于通过双膜理论运行模型，将传质作为稳态，而五个不同参数对 CO _{2 的影响}检查吸收效率以验证模型。建模结果与实验数据吻合较好，平均绝对偏差小于7.0%。过程分析表明，转速和PZ 浓度对CO ₂吸收效率的影响最为显着。
