Multi-objective optimization of reactive extractive distillation with ionic liquid-based entrainer for sustainable separation of the Allyl Acetate-Allyl Alcohol-Water system
This study focuses on the separation problem of the allyl acetate/allyl alcohol/H2O azeotropic system. With the help of extractive distillation and reactive extractive distillation technology, the system is optimized in combination with thermodynamic analysis and process intensification strategy. Based on the COSMO-SAC model, ionic liquids entrainers are screened, and six candidate entrainers such as [PMIM] [NO3] are determined by comprehensive evaluation, and their compatibility with the intermolecular interaction energy of the system is verified by quantum chemical calculation. The multi-objective optimization algorithm is used to determine [MIM] [NO3] as the optimal entrainer. Heat-integration and heat pump-assisted heat integration technology enhanced processes are introduced. After Economy-Environment-Exergy-Energy verification, the heat pump-assisted heat integration extractive distillation process is superior to the heat-integrated assisted extractive distillation. Compared with the traditional extractive distillation process, the annual total cost is reduced by 12.66 % and gas emissions are reduced by 30.19 %. Further considering the exothermic reaction of ethylene oxide and H2O, combined with the heat integrated enhanced process, the annual total cost is reduced by 17.61 % and gas emissions are reduced by 60.38 %. It is finally determined that the heat integrated assisted reactive extractive distillation process shows significant advantages in technical economy and environmental sustainability, providing an innovative solution for the clean separation of azeotropic systems.
期刊介绍:
Separation and Purification Technology is a premier journal committed to sharing innovative methods for separation and purification in chemical and environmental engineering, encompassing both homogeneous solutions and heterogeneous mixtures. Our scope includes the separation and/or purification of liquids, vapors, and gases, as well as carbon capture and separation techniques. However, it's important to note that methods solely intended for analytical purposes are not within the scope of the journal. Additionally, disciplines such as soil science, polymer science, and metallurgy fall outside the purview of Separation and Purification Technology. Join us in advancing the field of separation and purification methods for sustainable solutions in chemical and environmental engineering.
