Controlling and reducing flue gas emissions is a difficult task for coal plants, waste incinerators and other industrial plants. SO₂, SO₃, HCl, HF and other acid gases are a great threat and great harm to the environment and health; so treatments are required to meet air quality standards.
Custom Sodimate powder reagent discharge and metering systems can be used to handle a multitude of dry and semi-wet chemicals which are used to control emissions.
Storage, discharging and feeding systems are usually used for injections of calcium hydroxide (lime-off), highchair and sodium carbonate. In addition, mercury reduction can be achieved using powder activated carbon injection (PAC) technology.
