- Description:
- A mathematical model was assembled to simulate the sulfur dioxide removal from coal com-bustor flue gases by injection of aqueous sodium hydroxide solutions. The result show the extent of reaction strongly depends on the NaOH-SOz molar ratio and initial droplet size, the hydroxide concentration does not directly effect the reaction, and the NaOH-HjO mass ratio determines the time that solid crust starts to form or the reaction becomes liquid phase diffusion control. When the initial conditions are NaOH-SOz molar ratio equal to 2, NaOH-HjO mass ratio equal to 0.02, SOg concentration higher than 1000 ppm and droplet diameter less than 100 microns, the calculations indicate almost 100% SO2 removal from the flue gas can be achieved.
