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 CO2capture rates and product purity associated
with different capture technologies were further designed under each scenario. The impacts of CO2capture on the economic
benefits of calorific value variation of blast furnace gas were analyzed. When the CO2capture rate and CO2product purity were
equal,the calorific value of CO2per unit based on the fixed quantity raw gas scenario was higher than that under the fixed
carbon capture amount scenario. When the CO2capture rate was fixed,with the reduction of CO2product purity,the calorific
value benefits of CO2per unit mass based on the fixed quantity raw gas scenario and the fixed carbon capture amount scenario
were both higher. When the purity of CO2product was fixed,with the reduction of CO2capture 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.
