On-Line Monitoring and Optimization of Performance Indexes for Limestone Wet Desulfurization Technology

Abstract:

Taking No.11 flue gas desulfurization (FGD) site in Taiyuan Second Thermal Power Plant (TSTPP) as an example, the authors respectively deduced the models of technical performance indexes including SO₂ removal efficiency and outlet SO₂ concentration and the models of economical performance indexes including limestone consumption, power consumption and process water consumption. Then, by using the least square linear and nonlinear regression method, the authors obtained the practical mathematic models in the period of 21:00, Mar. 28th and 3:00, Mar. 29th, 2007. Finally, the authors calculated the optimal solutions of slurry pH value, calcium-sulfur (Ca/S) mole ratio and liquid-gas (L/G) ratio by utilizing the multiobjective programming method. Using this method, the desulfurization system works safely and economically.
