Simultaneous Desulfurization and Denitrification from Flue Gas Using Urea/Piperazine Solution

Abstract:

The simultaneous desulfurization and denitrification performance from the N₂-SO₂-NO simulated flue gas using the urea solution as the reduction absorbent and piperazine as the additive was investigated. The influences of the concentration of urea solution and the concentration of piperazine solution on the simultaneous desulfurization and denitrification behavior were also discussed. The experimental results showed that the addition of piperazine in the urea solution could enhance the denitrification performance, which could result the desulfurization efficiency of 94.07% and the denitrification efficiency of 85.11%.
