摘要:: 此研究将隔壁塔技术应用于催化汽油加氢装置，通过Aspen Plus V11建立热力学模型，

采用Peng-Robinson方程和DSO技术中试数据，系统比较了常规单塔、两塔与隔壁塔的分离效

能。结果表明，隔壁塔构型可实现三组分精准分离，中汽油馏程（84.8~162.5 ℃）完全满足重

整进料要求，芳烃潜含量达47.8%，加热炉热负荷降低41%。工业应用表明，该技术减产汽油

67.2 ×10⁴ t/a，增效1.344 亿元，为炼油厂低碳转型提供了新型分离解决方案。

This study applies the dividing-wall column technology to a catalytic gasoline hydrotreating unit. A thermodynamic

model was established using Aspen Plus V11, employing the Peng-Robinson equation and pilot-scale data from DSO technology to

systematically compare the separation efficiency among conventional single-column, two-column, and dividing-wall column

configurations. The results demonstrate that the dividing-wall column configuration achieves precise three-component separation,

with the medium gasoline fraction (84.8~162.5°C) fully meeting reformer feed requirements (aromatics potential content reaching

47.8%) while reducing heater thermal load by 41%. Industrial application shows this technology reduces gasoline production by

672 kt / year while generating additional benefits worth 134.4 million yuan, providing a novel separation solution for refinery

low-carbon transition.
