Designing a decarbonising closed-loop "Nature–Technology" control system

This paper considers carbon dioxide emissions from both energy and industrial enterprises in order to build a decarbonising closed-loop "Nature–Technology" control system based on the example of Beijing, PRC. Along with the known approaches to achieve atmospheric decarbonisation, the paper proposes an alternative approach to solving the problem based on a closed-loop "Nature–Technology" control system. Math-ematical models and basic approaches to the analysis and synthesis of a closed-loop "Nature–Technology" control system are proposed for the combination of energy and industrial enterprises as a basis for developing an appropriate automated process control system. The analysis and parametric synthesis of controls according to these models is based on mathematical modelling. In this case, the main criterion is to minimise CO2 emissions. The paper considers the construction of such a system as a part of energy and industrial enterprises, which might be applied to different types of production. The paper gives the stages of designing the main subsystems and links of the closed-loop "Nature–Technology" control system, which generates control and is implemented in the form of automated process control system. Final control regulators - filters, chemical adsorbers, catalysts and others are applied depending on the facility. This paper considers the natural fuel sources of the energy enterprises causing the highest CO2 emissions (coal, natural gas, etc.). As every fuel source is different in metric units and carbon content, this paper converts each source to standard coal with conversion factors. There are results on the status and prospects of the environmental situation regarding CO2 emissions in Beijing, PRC, estimates of energy consumption limits from energy and industrial enterprises. Based on the modelling of the proposed multidimensional control system, the authors propose a solution to the problem of minimising CO2 emissions for a combination of industrial enterprises and energy source enterprises (Thermal Power Plant). Taking Beijing, PRC as the example, the paper shows the possibility of fundamentally solving the problem of minimising CO2 emissions by implementing the considered decarbonising control system based on modern hardware and software modules automated process control system and an appropriate knowledge base.
