液液萃取分离技术基础性研究

This project developed and perfected new theories and viewpoints of extraction process thermodynamics and transport phenomena based on complex characteristics of multi-component, multi-phase and non-steady state emerging recently from chemical engineering and related fields. The phase scale, micro-scale and molecular scale methods are the analytical foundations. A series of aimed, highly efficient and non-toxic extraction processes and technologies as well as some integrated separation technologies have been developed. The substantial investigations of the project promoted the extraction separation to an advanced level in the aspect of technology and engineering. The study of the project will contribute greatly to the development and technological progress of high-tech and basic industries of China.

根据石化、冶金、生物、医药、环保等领域的需要，结合萃取分离过程中多组分、多相流及非稳态等特点，开展萃取分离技术中带有共性的基础理论和工程规律的研究，如分子间作用能及对萃取的强化、萃取设备内特性的非线性化研究、带有第三相的萃取分离技术、微尺度传递规律及原位耦合技术等，形成若干针对性的、高效、环境友好的萃取分离过程与技术。
