Abstract
In China, in steel works, byproduct gases account for almost 40% of total energy consumption. With the rise of energy price, increasing attention is paid on efficient and optimized utilization of byproduct gases recently. In this paper, a MILP model for optimization of byproduct gas is proposed. The objective function of this model is minimization of operation cost. Compared with previous optimization model, this proposed model chose short time period and considered the influence of Boiler Penalty Value (BPV) and Gasholder Penalty Value (GPV) on optimization results. The results based on real production data indicate GPV and BPV are sensitive to optimization results. Thus it is necessary to evaluate GPV and BPV reasonably. Compared with manual operation results, the optimal calculation results can reduce the fluctuation of gasholder and boiler so as to make the operation of byproduct gas system safe and stable.
