Discussion on integrated security control in process industry
Process industries such as chemical industry,metallurgy,petrochemicals,steel,papermaking,and electric power are important pillars of the country's economic and social development,and their safe and efficient production is of great strategic significance.The prominent characteristics of the process industry are the complicated long production processes and complex correlation and coupling of various processes.From raw materials to products,it involves various physical and chemical processes,such as mass and heat transfer processes,and interactions occurring in multi-source,multi-scale and multi-temporal and spatial,affecting the production safety,the efficiency of material and energy exchange and ecological environment as well.It has been a long-existing and changing problem for process industry to realize the integrated security.The core concern of integrated safety control of process industry lies in the reflection of mass flow and energy flow to digital flow,the transformation of digital flow to high-quality information flow,and the transformation of information flow to control flow.This paper puts forward a novel idea of integrated safety controls in process industry titled"five flows-three transformations-three controls",and discusses how to break through the digitalization of the mapping process from mass and energy flows to digital flow,break through the digital intelligence problem of the transformation from digital flow to high-quality information flow,and the decision lag problem of the transformation from information flow to control flow.It is expected to provide a new framework system basis for the integrated safety management and control in processindustry and promote the sustainable development of process industry.
