Abstract
A system & Method for Preventing Scaling in a Flue Gas Desulphurization System is provided. The system includes an injector configured to direct a barrier fluid toward a surface that is otherwise susceptible to scaling when it comes in contact with super-saturated alkaline solutions such as slurry used to capture CO2 from a flue gas stream.
Claims10
A system for controlling scaling in a flue gas desulphurization system comprising:
- an injector in a tank section of an absorber tower configured to direct an alkaline fluid outwardly therefrom against side interior walls of the tank section for alkaline fluid contact with the side interior walls of the tank section;
- and
- an aged alkaline slurry barrier in said tank section on side interior walls formed from alkaline fluid movement of aged alkaline slurry upwardly toward and into contact with said side interior walls reducing scaling thereon.
