Dry processes typically inject a dry sorbent into the flue gas before a particulate separator with the exception of the packed bed absorber (PBA). Usually, the particulate separator is either a bag filter or an electrostatic precipitator. They are designed to remove acidic gas components (mainly HF, HCl, SO2, SO3) by neutralizing them with alkaline sorbents. All dry processes can use calcium

Approximately 15–40% SO 2 removal can be achieved using a Ca/S in the flue gas molar ratio of 2.0. The optimum temperature for injecting limestone is ≈ 1900–2100°F. The calcium sulfate formed travels through the rest of the boiler flue gas system and is ultimately collected in the existing particulate control device with the fly ash and unreacted sorbent.
