Reuse of CO2 in energy intensive process industries

Reverse logistics is becoming more important in overall industry area owing to the environmental and economic factors. Planning and building a reasonable reverse logistics system could bring more profit, customer satisfaction and a nice social picture for companies. The energy-intensive industry is an important part of Chinas industry. We try to construct a reverse logistics system of the energy-intensive industries with the perspective of circular economy in this paper, which aims to reduce resources consumption and environmental pollution, and to promote economical, social and ecological environment development.

The chapter focuses on the historical aspect of economic development stages. It identifies agriculture-based, industrial, and post-industrial economies' characteristics. It is demonstrable that the problem of limited resources, the use of waste from consumption, and production has always existed. However, these problems were solved differently in different historical periods. The accumulated problems can be solved by the transition to a circular economy model. When studying the Russian experience in the transition to a circular economy model, the focus remains on Russian legislation. The example of Russian industrial enterprises shows the practical application of the circular economy principles. The research covers such enterprises as PJSC NK ROSNEFT (which includes PJSC ANK Bashneft, Bashneft-Ufaneftekhim, JSC Novokuibyshevsky Oil Refinery, and JSC Rospan International), PJSC TATNEFT, PJSC MMC Norilsk Nickel, PJSC Magnitogorsk Iron and Steel Works. The presentation is on strategies, policies, and programs aimed at ensuring industrial safety, labor protections, and the environment.

The article provides an overview of scientific research by scientists from around the world on the formation and implementation of the principles of a circular economy. Attention is also paid to the historical aspect of the formation of the stages of economic development. The characteristics of the agrarian, industrial and post-industrial economies are given. It is shown that the problem of limited resources and the use of consumption and production wastes has always existed. But these problems were solved in different ways in different historical periods. The solution to the accumulated problems is the transition to a circular economy model. Introduction of more advanced technologies allows not only to reduce the negative impact on the environment of current production activities, but also to reduce the volume of accumulated waste over the previous periods of production activities. When studying the Russian experience in the transition to a circular economy model, attention is paid to Russian legislation. The practical application of circular economy principles is shown on the example of a Russian industrial enterprise. The ecological program “Clean City”, which was developed at Magnitogorsk Iron and Steel Works, is considered. It should be implemented in stages until 2025. The ongoing programs require significant financial resources and cannot be implemented in the short term. The graphs show the result of the ongoing program: reduction of emissions of pollutants into the atmosphere, into water bodies, comparative data on specific emissions of sulfur dioxide (SO2) kg/ton of steel at the leading metallurgical plants in the world (2017). The environmental safety of the production processes of the Magnitogorsk Iron and Steel Works is ensured not only by advanced technologies, but also by modern methods of environmental management. The enterprise has implemented an environmental management system in accordance with the requirements of the international standard ISO 14001, which is confirmed by a certificate issued to the enterprise. The independent appraisal of the enterprise in 2018 was carried out by the Living Planet TV channel and the Modern Media Institute (MOMRI); energy rating agency Interfax-Era; World Wildlife Fund (WWF).

Preheating furnaces, which are commonly used in many production sectors (e.g., iron and steel), are simultaneously one of the most energy-intensive devices used in the industry. Partial replacement of natural gas with biomass-derived synthesis gas as a fuel used for heating would be an important step towards limiting industrial CO2 emissions. The time dependent computational fluid dynamics (CFD) model of an exemplary furnace was created to evaluate whether it is possible to obtain 40% of energy from syngas combustion without deterioration of thermal parameters of the treated load. As an outcome, a promising method to organize co-firing in the furnace was indicated. The obtained results show that the co-firing method (up to 40% thermal natural gas replacement with syngas), assuming low air-to-fuel equivalence ratio (λNG = 2.0) and even distribution of power among the furnace corners, lead to satisfactory efficiency of the heat treatment process—the heat transferred to the load exceeds 95% of the heat delivered to the load in the reference case), while carbon dioxide emission is reduced from 285.5 to 171.3 kg CO2/h. This study showed that it is feasible (from the heat transfer point of view) to decrease the environmental impact of the process industries by the use of renewable fuels.
