Wet Limestone-Gypsum Flue Gas Desulfurization System

Principle

Wet Limestone-Gypsum Flue Gas Desulfurization System removes SO2 ...

Solution Summary

Limestone slurry absorbs SO2 then it is oxidized by air-blowing at the lower part of absorber tower to produce calcium sulphite. The full chemical equation for Wet Limestone-Gypsum Flue Gas Desulfurization System is shown to find solution.
