摘　　要：化工过程通过物质和能量的可控转化和传递来实现化工产品制备,具有多相性、非线性、非平衡、多尺度和多时空域等特性,化工行业智能制造发展的关键是实现多尺度条件下的互联协同与过程高效。一方面,化工过程多尺度互联机制的认识和调控是化工过程系统的安全可靠运行的关键;另一方面,实现化工过程多尺度下的互联、融合与协同是化工产业绿色发展的路径。鉴于此,本文提出了化学工业面向多尺度融合的智能制造模式——互联化工,给出了"互联化工"的概念、目标、特点和架构,并讨论了互联化工的相关关键技术,包括化学工业多层级的信息物理系统、云制造,以及全生命周期的安全管理技术、耦合互锁机制下的动态安全监控与决策模型、基于区块链的互联化工数据安全技术。The manufacture of chemical products is realized through the controlled conversion and transfer of mass and energy in chemical processes with diversity features,such as polyphasic,nonlinear,non-equilibrium,multi-scale and multi-spatial etc.The key of the development of intelligent manufacturing in the chemical industry is to achieve the interconnection between the involved subsystems and high process efficiency under multi-scale conditions.On the one hand,the understanding and regulation of the multi-scale interconnection mechanism of chemical processes is crucial for the safe and reliable operation of chemical systems.On the other hand,the realization of the interconnection,integration and collaboration between the subsystems at multiple scales in the chemical processes is the way for the green development of the chemical industry.Therefore,this work proposed an intelligent manufacturing mode for multi-scale integration in the chemical industry,which was identified as interconnected chemical engineering.In this paper,the concept,objectives,features and technical framework of interconnected chemical engineering were provided.The key technologies of interconnected chemical engineering were discussed.They included multi-level cyber-physical systems in the chemical industry,cloud manufacturing,the secure technologies of product lifecycle management,the model of dynamic safety monitoring and decision-making under the coupling and interlocking mechanism,and blockchain-based security technology with interconnected chemical data.
