Spray Dry Absorber (SDA) Optimization

Spray Dry Absorber (SDA) Optimization

Background. Spray Dryer Absorbers (SDAs) are designed to remove acid gases, mainly sulfur dioxide (SO2), from flue gas streams. Atomizers are used to inject droplets of lime slurry into the SDA reaction chamber, which then evaporate and react with the sulfur dioxide in the flue gas to form calcium sulfate, a solid powder that is typically ...

The design gas residence time in a spray dryer absorber is about a sixth of a minute, to provide enough time for evaporation and reaction with SO 2. To allow for this, the spray drier absorber vessel would be close to 40 feet diameter and 65 feet high for both boilers (EPA, 2000).

Spray Dryer - an overview ScienceDirect Topics

The droplet size distribution and the residence time are the most relevant parameters in spray dryers, and they are crucial to enhancing SO 2 -sorbent contact and thus high SO 2 removal efficiency. The flue gas enters into the absorber bottom at 120–150 C and evaporates the water introduced with the slurry.

Spray Dryer Design

The most important variables in the design of a spray dryer are the evaporation rate and the required particle size distribution of the product. The evaporation rate and the dryer ΔT (inlet air temperature minus the outlet air temperature) dictates the amount of drying air needed, which dictates the sizing and cost of almost all of the system ...

The rotary atomizers were used to spray water to maintain a temperature below this permitted temperature. The plant struggled with operating the SDA’s to cool the gases, so that the temperatures could be kept below 300F. The Atomizer also had issues with hopper wetting and this de-rated the boiler in multiple instances.
