Minimizing Pollution Effects through Recovery of Gases Thermal Energy from the Scrap Recycling Process

This study consists of minimizing the pollution effects of the recycling industry through the application of new duplex systems, which could be used for the purification and regeneration of the gases in smelting scrap. In the first phase, the process of recovering thermal energy from the scrap melting process will be based on creating a thermal profile and managing furnace zones, whose theoretical profile will be based on thermal analysis data. The previous preparation of the filling would be based on the data of the chemical analysis of the smelting products and process gases and the chemical and granulometric analysis of the flux and coke. In the second phase, the ratio of CO₂: CO in the process gases will be regulated, which is the most important indicator of the effectiveness of waste recycling through the scrap melting process. Industries, especially those for energy generation and recycling, due to outdated technological schemes, improper management of industrial waste resulted in a lower level of utilization of natural resources and energy and a high level of environmental pollution. According to the results of this study, minimization of environmental pollution and problems related to the efficiency of the process would be possible between the integration of gas cleaning equipment in CSC systems and/or the application of SCHACK systems. The application of this system would enable the minimization of pollution from greenhouse gases (CO, CO₂, NO_x, SO₂, etc.) and their return to the process will guarantee energy recovery and generally improved process efficiency. According to this pilot project, the gases that are released from the process of melting waste from the scrap in the cupola furnace of the
