In China, more than 90% of coal-fired power plants adopt the wet limestone flue gas desulphurization (FGD) process to control the emissions of sulphur dioxide due to its high desulphurization performance, reliability and low utility consumption [15], thus a great deal of the by-product (FGD gypsum) is produced from such process.

The cocurrent contact of slurry and flue gas allows for a higher flue gas velocity and results in a reduced pressure drop. Additionally, combining the cocurrent absorber tower and reaction tank can reduce space requirements. In this design, limestone slurry is sprayed above the grid and is contacted by the flue gas.
