摘要: 以连续重整-芳烃联合装置的重整生成油为原料,利用PRO Ⅱ流程模拟软件分别对采用常规两塔工艺流程和分壁塔工艺流程的两种重整生成油分离方案进行模拟,在保证分离产品质量一致的情况下,从能耗、设备投资和占地的角度分析对比两种方案的优劣。结果表明,与常规两塔工艺流程相比,分壁塔流程的能耗降低31.2%,设备投资节省20.3%,占地面积减少38.3%。

Abstract: On the basis of reformate data from a CCR-aromatics complex unit, two process flows including a dividing wall column (DWC) configuration and a conventional two-column configuration for the separation of reformate are simulated by PRO II software and compared under obtaining the same qualities of products. It is concluded that compared with the conventional two-column process flow for DWC process flow the reductions of energy consumption, equipment investment cost and area occupation are approximately 31.2%, 20.3% and 38.3%, respectively.
