Key Data Set Information
Location CN
Geographical representativeness description The average operating data of Coal-DR, NG-DR (MID), and NG-DR (ENE) demonstration projects in China are used as the benchmark for the LCI of DR routes.
Name
DRI production;DRI;NG-DR (MID)
Use advice for data set When utilizing the Life Cycle Inventory (LCI) data of Direct Reduced Iron production routes, ensure appropriate modeling of the specific technology (Coal-DR, NG-DR (MID), NG-DR (ENE), COG-DR, H-DR) adapted in the process. Since LCI is based on the average operating data from demonstration projects and supplemented by literature data from simulations, laboratory tests, and process modeling, users should confirm the alignment of their context with the Chinese benchmarks provided. Considerations of scaled-up feasibility, technology maturity, and regional variability must be taken into account for accuracy. For routes not fully scaled-up in China, such as COG-DR and H-DR routes, additional care should be taken to adapt the LCI data to the specific context of deployment.
Technical purpose of product or process Direct Reduced Iron (DRI) produced using the Natural Gas Direct Reduction (NG-DR) method, specifically the MID process, is used primarily as a raw material for steelmaking. In contrast to traditional blast furnace methods, NG-DR offers a cleaner and more energy-efficient means of producing iron units for use in electric arc furnaces (EAFs) or for further processing into various steel products.
