Power plant desulfurization
limestone / lime - gypsum wet, boiler flue gas booster fans pressurized by gas - gas heat exchanger to cool after switching into the desulfurization tower, bottom-up flow through the desulfurization tower, with the top down limestone / lime slurry is formed reverse flow, heat exchange and simultaneous chemical reaction to remove flue gas SO2.

5、Using jet-style regenerator to achieve self inspiration of air. Desulfurization solution premix and regenerate. Air will be compressed and saved with less off-gas discharged during the regeneration. The amount of nitrogen in the off-gas is far below relevant standards of the nation. 【One-tower Process of Desulfurization Regeneration】

The Story of Desulfurization Tower and Scale Inhibitor
Aug 05, 2019 · First, look at the limestone - gypsum wet flue gas desulfurization process. The biggest one above is the desulfurizer tower It does a lot of work Industrial processes release a lot of SO 2, which is absorbed in the desulfurizer tower Reaction Steps. So you don't have to worry about SO 2 emissions When you're relaxing

Desulfurisation – BSBSUCCEED
In the double-alkali method, sodium-based desulfurization mechanism agent is used for desulfurization in the tower. Since sodium-based desulfurization agent has strong alkalinity, the reaction product has high solubility after absorbing sulfur dioxide, which will not cause supersaturated crystallization and cause scaling and clogging problems.
