The described process refers to the production of Direct Reduced Iron (DRI) using coal-based direct reduction processes. Typically, this DRI production is part of the steelmaking industry, where it serves as a cleaner, alternative iron source to traditional blast furnace methods. The process utilizes by-product gas from coke ovens (Coke Oven Gas, COG) in a Direct Reduction Iron (DRI) generation process. It applies to industrial steel production facilities seeking to reduce their dependency on coking coal and increase their energy efficiency and lower their greenhouse gas emissions. When using this LCI data set for the direct reduction iron (DRI) route, it is crucial to reference the average operating data from relevant Chinese demonstration projects. The methodological advice includes ensuring that modeling reflects the specific technological applications and energy inputs outlined for the COG-DR and H-DR routes, with consideration of the scalability within the Chinese context. The data should be utilized with attention to the fact that it includes estimates from simulations, laboratory tests, and process modeling, and thus may require adjustment when applied to contexts or technological setups outside of those studied. Additionally, when considering the LCI data for inclusion in comprehensive environmental assessments, ensure that system boundaries are properly defined, especially regarding the inclusion or exclusion of subsequent recycling processes.
