Study Notes
Dissolution Process
- Heat from high-pressure steam is used to raise the temperature of the mixture in the first dissolving reactor.
Flow of Dissolved Liquid
- The dissolved liquid flows over to the second stage dissolving reactor after the completion of the reaction.
Emission Control
- Ammonia is added in the first dissolving reactor to control NOx in off-gases.
Scrubbing Process
- The unreacted sulfur dioxide is discharged with CO2 and H2O vapor to a scrubber during the dissolution process.
Anti-Foaming Agent
- Silicone-based antifoam agents are sent to the first dissolving reactor to avoid foaming during the reactions.
