采用蒸汽再压缩技术可以提高分隔壁塔的能效,但分隔壁塔顶底温差大限制了蒸汽再压缩技术的应用。为了充分回收大压缩比下VRC产生的热量,本文提出了VRC辅助DWC的新的强化热集成。在强化配置中,再沸器冷凝液体用于在中间再沸器(IR)中蒸发侧液流,塔顶蒸气由过冷液体预热。利用DWC的柱整体合成曲线(CGCC)可以确定最佳IR位置。对3种不同ESI值的分离工况进行了模拟计算,验证了强化结构的能量容量,结果表明,强化热集成技术可以显著提高顶底温差较大的DWC的能量效率。
The energy efficiency of dividing wall column (DWC) can be improved by the vapor recompression (VRC) technology, but large temperature difference between the overhead and bottom of the DWC limits the application of VRC. To fully recover the heat generated by the VRC under large compression ratio, new intensified heat integrations of the VRC assisted DWC are provided in this paper. In the intensified configurations, the reboiler condensed liquid is used to vaporize the side liquid stream in an intermediate reboiler (IR), the overhead vapor is preheated by the subcooled liquid. The best IR position can be gotten by the aid of the column grand composite curves (CGCC) of the DWC. Three separation cases with different ESI values are simulated to validity the energy capacity of the intensified configurations, the results show that the intensified heat integration technolgy can significantly improve the energy efficiency of the DWC with large temperature difference between the overhead and the bottom.
