Abstract |
The report utilizes current understanding of limestone scrubbers for flue gas desulfurization (FGD) to develop an effort into the optimization of automatic control for the recirculating slurry processes. The acknowledged methods of mathematical modeling, computer simulation, and experimental proofing are applied to the design of slurry limestone addition, slurry density, and absorber liquid-to-gas (L/G) ratio control systems. Three automatic control methods are analyzed for dense limestone feedrate to the recirculating slurry: stoichiometric control, pH control, and stoichiometric-assisted pH control. Absorber L/G ratio control for minimizing scrubber energy requirements while maintaining an SO2 exit target is also designed, based on a feedforward SO2 removal law and slurry pump selection. |
