Reducing carbon dioxide emission of a metallurgical plant

Most of the blast-furnace gas produced by the plant is used for heating of blast air as well as steam and electricity production. However, a significant part of it remains unused and burned outside the technological units, and the combustion products are released into the atmosphere. The analysis and optimization of the fuel balance of the metallurgical plant have been carried out. The gross emission of carbon dioxide has been chosen as the optimality criterion. Minimization of the criterion has been achieved by the full use of blast-furnace gas and reducing natural gas consumption of the plant. It has been determined that the reduction of carbon dioxide emissions is 10 300 t/year.
