CO2 reduction using a blast furnace utilizing hydrogen - dew point meter and oxygen concentration meter.
Introduction of measuring instruments for managing CO2 reduction using a carbon recycling blast furnace utilizing hydrogen.
Around us, we supply the highest quality steel in the world, including ordinary steel, special steel, ultra-high tensile steel plates, and electrical steel plates, to industrial machinery and automobiles, which are essential for a carbon-neutral society. We aim for "green steel," targeting decarbonized steelmaking by utilizing CCUS (carbon capture, utilization, and storage). As part of this effort, the development of steelmaking technologies using hydrogen is underway. One example is hydrogen reduction technology, which synthesizes methane from carbon dioxide and hydrogen emitted from the reduction furnace (methanation) and uses it as a reducing agent to remove oxygen from iron ore (Fe2O3) used in blast furnaces. By reducing low-grade iron ore solely with hydrogen instead of coal, we can minimize carbon dioxide emissions during steel production. In addition to hydrogen-based developments, efforts are also being made to produce steel products by rapidly melting direct reduced iron and scrap in electric furnaces.
basic information
Regarding current steelmaking technology: Cokes, which are produced by the dry distillation of coal, and iron ore are charged into a blast furnace, where iron is extracted from the iron ore while simultaneously performing processes to melt the iron ore to produce steel. In line with the Ministry of Economy, Trade and Industry's "Green Growth Strategy for Carbon Neutrality by 2050," various industries are undertaking efforts to reduce greenhouse gas emissions. Reference: Ministry of Economy, Trade and Industry / Agency for Natural Resources and Energy / Manufacturing Industries Bureau Tekune Measurement offers measuring instruments tailored to your applications. We have dew point meters and anemometers for dew point and moisture management, as well as thermohygrometers with environmental resistance. For more details, please contact us.
