    Circulating dry-scrubbing processes inject dry hydrated lime or humidified pulverized quick lime into a separate reaction vessel. With all three processes the acidic gases combine with lime to form a dry product that is removed from the flue-gas stream in particulate-control devices such as baghouses or electrostatic precipitators.
