Help promote the chelated iron technology along the way.
The main problem with alkali washing is the generation of waste brine or by-products; the ammonia method allows for product production, but there are issues related to vapor leakage from ammonia-based systems
Do you mean ammonia escape by volatility? What does leakage refer to? Is it caused by pipe corrosion?
After the flue gases leave the incinerator, they need to be further cooled before undergoing alkaline washing. If ammonia is used for this washing process, considerations must be given to the risk of ammonia leakage. The purpose of alkaline washing is mainly to handle emissions of SO2 and other by-products; generally, a 20% sodium hydroxide solution is used for this purpose. After the alkaline washing, a pump is used to transport the solution, and a pH detector is necessary to adjust the flow rate of sodium hydroxide
