摘要

通过混合溶剂作为夹带剂和热耦合技术来增强萃取蒸馏过程,提出了一种分离二乙氧基甲烷/乙醇/水共沸体系的可持续高效工艺。通过分子模拟技术精确探索了不同分子之间的微观机理,并确定了合适的候选夹带剂。在此基础上,进一步设计了使用不同溶剂作为夹带剂的萃取蒸馏工艺。通过多目标优化,改进了工艺的操作参数。在优化溶剂萃取蒸馏工艺的基础上,进一步引入了与热泵和热集成技术相结合的萃取蒸馏工艺。结果表明,与基本工艺相比,强化工艺的年总成本降低了 3.14%,气体排放量减少了 29.02%。这项研究不仅为萃取精馏工艺的设计提供了新思路,更重要的是为混合夹带器的筛选和工业应用提供了参考。

Separation for diethoxymethane/ethanol/water by a thermally coupled extractive pressure swing distillation process with mixed solvent
A sustainable and efficient process for separating diethoxymethane/ethanol/water azeotropic systems was proposed via a mixed solvent as an entrainer and thermal coupling technology to enhance the extractive distillation process. The microscopic mechanisms between different molecules were precisely explored through molecular simulation technology, and suitable candidate entrainers were determined. On this basis, extractive distillation processes using different solvents as entrainer were further designed. The operation parameters of the process were improved by multi-objective optimization. The extractive distillation process coupled with heat pump and heat integration technology was further brought in based on the optimal solvent extractive distillation process. The results indicate that the intensification process reduces the total annual cost by 3.14% and gas emissions by 29.02% compared to the basic process. This study not only provides a new idea for the design of extractive distillation process, but more importantly, it provides a reference for the screening and industrial application of mixed entrainer.

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.
