Abstract

Flue gas condenser can solve subsequent environmental problems caused by wet desulfurization. In order to realize the numerical prediction of the removal of SO₂ and NO in flue gas condenser, based on the vapor-liquid equilibrium and chemical absorption equilibrium of condensate and solute gas, the relationship between the chemical equilibrium constants and the mole fraction of SO₂ and NO was determined. The process including flow, heat transfer, condensation of steam and absorption of SO₂ and NO by condensate in the flue gas condenser was simulated by numerical method. The results showed that: under one certain operating condition, the condensation efficiency of steam was 16%, the removal rate of SO₂ was 12.14%, and the removal rate of NO was 9.2%. The numerical simulation results showed good agree with the operation measurement data.
