Abstract

Abstract:

One of the main tendencies of sustainable chemical engineering is to develop green technologies with the aim of eliminating pollution by preventing it in the first place, and thus, any breakthrough of single unit technology could make significant contributions to a new green technology. However, process engineering is a complex system which covers multiple units and sub-systems, including utilities, waste treatment and so on. Hence, besides single technology innovation, the whole chain covering raw material substitute, unit intensification and system should be highlighted during process development, and meanwhile considering the economic and environmental constraints. Also, along this chain, the novel materials/solvents and processes innovation are important for the process greening. On the base of the principles of system engineering and considering the research frontiers of the green process engineering, and taking new ionic liquids as key material, this article reviews the latest progresses in the aspects of raw material substitution, solvent innovation, transfer properties and process integration. The proposed viewpoints and methodology could become important bases to develop new green technologies, and also construct the science of green process system engineering subject.

Key words: green process system engineering, process systems, green technology, ionic liquid, hydrogen-bond, simulation

摘要：

发展从源头消除污染的绿色技术是过程工业可持续发展的必然要求,任何单元技术的突破对过程工程的绿色化都是不可或缺的。然而过程工程是一个系统科学,不仅要考虑单个技术,重点还要考虑从原料替代、介质创新到单元强化及系统集成的整个链条,归根到底是要通过新介质(如催化剂、溶剂等)的原始创新和新工艺集成创新实现过程工业的绿色化。基于系统论的科学思想综合考虑过程工程这一复杂大系统,以离子液体介质创新为核心,综述了在原料替代、新型介质设计、传递规律、系统集成方面的新进展,以期为绿色化工技术的发展提供重要的科学基础。
