The Research on SO₂ Desorption Equilibrium Mechanism of Sodium Alkali Desulfurization Regeneration Solution

Abstract:

Sodium alkali flue gas desulfurization (FGD) is one of the most promising renewable FGD technologies, and the SO2 gases desorption in desulfurization regeneration solution is very important to directly affect its application. Based on the gas-liquid equilibrium relationships, this paper researched the equilibrium mechanism of SO2 desorption in the sodium alkali desulfurization regeneration solution. The results showed that SO2 desorption process is a mass transfer process that SO2 transfer from liquid phase to gas phase essentially, and SO2 desorption limit capacity depend mainly on the gas-liquid equilibrium relationship. Moreover, the formula of SO2 desorption limit capacity at equilibrium condition was deduced through analyzing desorption equilibrium relationships, and the main factors are also discussed.
