The performance and effectiveness of the conventional and heat-integrated side-stream extractive distillation arrangements are explored with the simultaneous consideration of the steady-state economics, thermodynamics and dynamic controllability aspects of the process. The overall performance of simple stream-to-stream heat-integrated F-S-E configuration (serially preheating column inlet feeds by solvent stream) is superior to others because of the least total annual cost (TAC), CO₂ emissions and highest second-law efficiency among these side-stream cases. It can further reduce 8.16% in TAC compared to the conventional extractive distillation configuration. Exergy and entropy generation analyses are employed in these heat-integrated side-stream extractive distillation arrangements to thorough evaluate the energy degeneration in each component. Furthermore, dynamic control analyses for conventional and heat-integrated side-stream extractive distillation processes are also explored. Two novel compromised tactics are proposed to make the economically optimal heat-integrated arrangement more stable at rejecting large feed disturbances according to the physical implemented issues of economizers. Both effective and robust dual-product quality controls are provided for tackling the large (20%) throughput and feed composition perturbations. Furthermore, a new developed control scheme with parallel arrangement works better than that with series exchangers’ arrangement by comprehensively weighing results of steady-state economic design and dynamic controllability.

在兼顾过程的稳态经济性，热力学和动态可控性的同时，探索了常规的和热集成的侧流萃取蒸馏装置的性能和有效性。简单的整体性能流-到-流热集成FSE配置（串联预热柱入口通过溶剂流进料）是优于其它，因为至少总年度费用（TAC），CO的₂这些旁流案例中的排放和最高的第二律效率。与传统的萃取蒸馏配置相比，它可以进一步降低TAC的8.16％。在这些热集成侧流萃取蒸馏装置中，采用了能级和熵生成分析，以全面评估每个组件中的能量退化。此外，还探讨了常规和热集成侧流萃取蒸馏过程的动态控制分析。提出了两种新颖的折中策略，以根据省煤器的实际实施问题，使经济上最佳的热集成装置在拒绝较大的进料干扰时更加稳定。提供了有效且强大的双重产品质量控制，以应对较大的吞吐量（20％）和饲料成分扰动。此外，通过综合权衡稳态经济设计和动态可控性的结果，新开发的并联布置的控制方案比串联交换器的布置更好。
