Abstract

Abstract

In this study, three carbon capture scenarios were designed, namely fixed quantity raw gas scenario, fixed carbon capture amount scenario, and mixed raw gas scenario. Cases reflecting different CO₂ capture rates and product purity associated with different capture technologies were further designed under each scenario. The impacts of CO₂ capture on the economic benefits of calorific value variation of blast furnace gas were analyzed. When the CO₂ capture rate and CO₂ product purity were equal, the calorific value of CO₂ per unit based on the fixed quantity raw gas scenario was higher than that under the fixed carbon capture amount scenario. When the CO₂ capture rate was fixed, with the reduction of CO₂ product purity, the calorific value benefits of CO₂ per unit mass based on the fixed quantity raw gas scenario and the fixed carbon capture amount scenario were both higher. When the purity of CO₂ product was fixed, with the reduction of CO₂ capture rate, the calorific value of fixed quantity raw gas scenario increased in efficiency, while the calorific value of the fixed carbon capture amount scenario decreased in efficiency.
