Simultaneous Desulfurization And Denitrification

In this paper, we mainly introduced demonstration project of flue gas desulfurization and denitrification achieved by ozone oxidation and alkali wastewater. The System showed high automatization, which performed good adaptability and load tracking capacity on the concentration of SO2, NOXand variation of flue gas. Meanwhile, outlet concentration of the SO2and NOXcould meet the design requirements. The experimental results showed that the overall economy of designed process had certain advantages compared with conventional desulfurization and denitrification technologies.

Design Requirements

Anti-corrosion coating in desulphurization flue of one wet flue gas desulfurization equipment (FGD) (model 1 and model 2) was designed and studied according to environmental and technical parameters of a coal-fired power plant. And relevant design requirements were confirmed. Application results showed that polyureas has wear and high temperature physical properties, so that it can be used in flue desulfurization equipment for anticorrosion. When the construction of a thickness of 2.0 mm, the high-temperature polyureas protective coating appearance smooth, EDM(electric discharge machining) 100% pass rate, adhesion 10.8 MPa, at 160 °C environment still had outstanding performance, that make sure it could reach its design life of the flue based on estimating the corrosion margin.

Simultaneous Desulfurization And Denitrification

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%.

Desulfurization Activity

Sorbent of CuO loaded on complex carrier of attapulgite and activated carbon was prepared by incipient impregnation method for flue gas desulfurization. The effects of CuO loading, reaction temperature and components in flue gas on the desulfurization performance were investigated in a fixed-bed quartz reactor. The experimental results indicate that the sorbents of 20 wt% CuO loading has a high desulfurization activity under conditions of reaction temperatures 200-250 oC and 21000 h-1, and O2 is necessary for the high desulfurization activity of the sorbents.
