A power plant of Datang Corporation in Hebei province is to reconstruct its wet flue gas desulfurization system. The power plant proposes three viable capacity extension schemes based on actual conditions: adding spray layers and increasing the height of the existing absorber, desulphurizing with series double-absorber and desulphurizing with dual-cycle double-absorber. This paper describes the technical characteristics of the schmes and compares their advantages and disadvantages based on performance, project investment and construction period. The result shows that the double-absorber scheme is more suitable for the power plant than the single-absorber scheme.
