Integrated technology selection for energy conservation and PAHs control in iron and steel industry: Methodology and case study

► We predict technical strategy for energy and PAHs reduction in iron and steel mill. ► With low PAHs control objectives, process control technologies are preferable. ► With medium & high PAHs control goals, alternative smelting technology is dominate. ► In low PAHs control objective, 25% energy reduction is a threshold.
