Study on Dynamic Optimization Model of Surplus Gas Distribution in Iron and Steel Plant

This paper analyzes the byproduct gas utilization and management status of china's iron and steel plant, point out that the dynamic optimization of surplus gas distribution has a very important position in the management of gas system, and a common model is established using mixed integer MILP (linear programming) method. Two typical enterprise application results show that: The model suitable for different types of iron and steel plant; optimization model can take full account of the characteristics of the adjustable users, CCPP(Combined Cycle Power Plant), blending boilers and gas tanks to maximize overall efficiency; diversification of the buffer unit to ensure security and stability of gas system and qualified enterprises should establish CCPP.
