Abstract:

An evaluation was conducted on the co-control effect of energy-saving and emission reduction measures in the iron and steel industry. The results could be used to support the co-control planning of local air pollutants and greenhouse gases reductions. The emission factor method was used to calculate the emission reduction of various local air pollutants and greenhouse gases by different measures. Various emission reductions were then converted into Integrated Air Pollutant Co-control Emission Reduction (ICER). Co-control effects coordinate system, co-control cross elasticity, unit pollutant reduction cost and the marginal abatement cost curve were applied to examine the co-control effects for different measures. The results show that, in 2025, the 28 measures in the iron and steel industry can reduce SO2 emission by 518.0 kt, NOx by 713.5 kt, PM10 by 290.7 kt, and CO2 by 664 Mt. Except for end-of-pipe decarbonization and pollution reduction measures that do not have co-control effects, the other 25 measures have good co-control effectiveness. The “High-Temperature/High-Pressure Boiler Technologies for Coke (T3)” has the lowest cost, and the “Ultra-Low Emission Retrofitting (T28)” has the highest cost. Most energy-efficiency improvement measures, raw (fuel) material substitution measures can bring benefits (or reduce costs). Structural adjustment and energy-efficiency improvement measures have the greatest potential for emission reduction. In the future, the co-control technology development and co-control planning in the iron and steel industry should be strengthened to realize the optimization of the co-benefits of local air pollutants and greenhouse gases synergetic reductions.

Key words: Iron and steel industry, Co-control, Effectiveness evaluation
