OPTIMIZATION OF DESULPHURIZATION PROCESS IN A FLUE GAS ABSORBER BY ADJUSTING FLOW PATTERNS AND ROTARY ATOMIZER

Original language description

Efficiency of desulphurization process in a flue gas absorber depends strongly on flow patterns of the continuous gas phase and interaction with water slurry phase that is injected into the absorber. The main task is to ensure that undesulphurized flue gas moves optimally to where a high concentration of water slurry in the form of droplets flies. In the paper, a model for desulphurization process is presented. The problem was solved using commercial CFD code StarCD into which a model for desulphurization was integrated. The model distinguishes between two phases of heat and mass transfer. One called constant rate period, where the water droplet formed by an gregate of calcium hydroxide particles encapsulated in water evaporates by convection mechanismand sulphur dioxide is transferred by the same mechanism. In this phase the spherical reaction front recedes as calcium hydroxide is converted. In the second phase called falling rate period water is contained only in the free space betw
