Combination of Absorber and Chimney Limestone/ lime-gypsum Wet Process FGD

Process Introduction

The flue gas from electrostatic precipitator is discharged into absorber and reacts with limestone slurry through booster fan, and produces gypsum. The treated flue gas after desulfurization is emitted into the atmosphere by the straight chimney set at the top of absorber. Through two times dehydration, the moisture content of gypsum is not more than 10%.

Technical Features

 Smaller footprint, especially suitable for retrofit project with limited space; 

 No need to reconstruct the old stack; 

 Lower capital cost (without GGH and treated gas duct) and operation energy consumption; 

 Shorter construction duration (about 4 months can be shortened).
