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 based (ENE)
Use advice for data set When utilizing the life cycle inventory (LCI) data of the DRI production processes, namely Coal-Based DR (Coal-DR), Natural Gas-Based DR (NG-DR) with mid-range efficiency (MID), and the energy-efficient (ENE) variation, users should refer to the operating data from Chinese demonstration projects as a benchmark. For the routes not extensively scaled in China, such as COG-DR and H-DR, the LCI should be extrapolated using the Coal-DR data in conjunction with simulation, laboratory test, and process modeling literature. Note that methodological considerations like system boundaries, data quality, and technological applicability need to be taken into account.
Technical purpose of product or process Direct Reduced Iron (DRI) production based on natural gas, specified as the Energy Efficient (ENE) process, is utilized in the manufacturing of steel as an alternative to the traditional blast furnace method. This process is used for producing iron that is often later converted into steel, which can be employed across various industries including construction, automotive, and appliance manufacturing.
