Agglomerate is one of the main types of raw material for blast furnace production. During the processes of agglomeration, cooling, and processing of agglomerate, a significant amount of harmful technological emissions is generated, including dust, carbon oxides, sulfur oxides, nitrogen oxides, and others. The agglomeration charge contains solid fuel such as coke fines and anthracite fines, as well as a significant amount of iron-containing waste, which is the primary source of sulfur in the metallurgical process. To address the issue of comprehensive flue gas treatment, a technology based on the use of a plasma-catalytic reactor (PCR) has been developed. The proposed solution optimizes the process of cleaning gaseous emissions, enhances economic efficiency, and reduces the environmental impact of the agglomeration process. Additionally, the technology opens up the possibility for further processing of iron-containing and sulfur-containing materials. The operating principle of the reactor is based on ozone generation in a corona discharge. Ozone ensures the complete oxidation of sulfur dioxide (SO2) into sulfur trioxide (SO3). The apparatus consists of a PCR unit, which generates the required amount of ozone by passing air through the corona discharge, and a power supply unit (transformer). The integration of the “MV-2JS” apparatus into traditional desulfurization technology allows for the complete elimination of the third stage of the process — the oxidation of calcium sulfite in special vessels. By installing the PCR directly before the reactor-adsorber in the flow path of the flue gases, instead of sulfur dioxide (SO2), sulfur trioxide (SO3) is obtained. This, in turn, allows the synthesis of high-quality commercial gypsum that does not contain harmful toxic impurities and does not require additional oxidation.
