Organization of industrial monitoring of the life cycle of copolymer production using LCA technologies

The article is devoted to the actual problem of organizing industrial environmental monitoring of the life cycle of production using information technology. In order to provide Russian enterprises with methodological recommendations for organizing a system of production control and monitoring in order to comply with legislation on maximum environmental standards and waste turnover, it is necessary to study and develop possible options for accumulating data and converting them automatically. The purpose of the article is to develop solutions for organizing a system for monitoring the impact of the stages of the life cycle of petrochemical production on the external environment using tools for continuous information support. To design information modules for assessing the impact of production processes on the ecosystem, sequential procedures of the LCA method were used. To optimize the parameters of environmental friendliness of the production of styrene-butadiene copolymer, the article solves the problem of linear programming; the database for solving the linear programming problem is based on materials from information and technical reference books on the best available technologies, reference books on standards for maximum permissible concentrations of pollutants. The use of the method of information support of the life cycle of LCA products for the organization of automated industrial environmental control and monitoring is scientifically substantiated. A model of the production chain is formed and a block diagram is presented for assessing the impact of the life cycle of chemical production on the ecosystem using the LCA method in the absence of a standardized technology for the accumulation and exchange of environmental data, various levels of automation and digitalization of production processes in petrochemical industries. The flows at the boundary of the chemical-technological system for the production of styrene-butadiene copolymer are investigated and a possible variant of their mathematical optimization is proposed. By solving the linear programming problem, the optimal values of resource consumption for the production of butadiene-styrene copolymer were obtained, at which the minimum indicators of pollutant emissions into the ecosystem are possible: butadiene - 725 kg/t; styrene - 313 kg/t; electricity - 830 kWh/t; water steam - 9.0 Gcal / t. Examples of chemical-technological systems have been identified, where the use of butadiene and styrene relative to the obtained optimal parameter leads to overexpenditure of resources. The research materials can be used in the development of programs and the choice of tools for automated industrial environmental control and monitoring in chemical-technological systems.
