Key Data Set Information | |
Location | CN |
Geographical representativeness description | The data of the BF-BOF pathway were obtained from the large-scale integrated steel plants in China with an attached coking plant and EAF plant. |

Use advice for data set | When utilizing this data set, it is important to include emissions from coke production as part of the upstream process for iron and steel production. Modelers should ensure that the system boundaries include both the coking plant and EAF operations if assessing the entire steel production route. Differences in technology variations across different integrated plants should be considered, and region-specific emissions factors must be used when applying this data set to other locations. |
Technical purpose of product or process | The described process is used in the production of coke through coking and CDQ (Coke Dry Quenching) technology. This coke is primarily used as a reducing agent and energy source in blast furnaces (BF) during ironmaking, which precedes the basic oxygen furnace (BOF) steelmaking process. It is also used in Electric Arc Furnaces (EAF) for steel production at integrated steel plants. |
