Numerical Investigations for the Two-Phase Flow Structures and Chemical Reactions within a Tray Flue Gas Desulfurization Tower by Porous Media Model

The computational cost of the full-scale flue gas desulfurization (FGD) tower with perforated sieve trays is too high, considering enormous scale ratio between hole at tray and relevant size tower. As a result, porous media model used to replace complex structure in this study, which has been validated for measured data both small- FGD Under lower inlet volume flow rate, simulation result four-tray indicates that uprising high SO2 mass fraction can move along wall This region lacks two-phase mixing and, hence, its efficiency similar empty one-tray towers under same conditions. However, when rate increases, liquid column becomes larger because stronger inertial flow. In situation, implementation suppresses deflection provides better within trays, leading noticeable increase efficiency. study insightful information design guideline industries.
