摘要：The agent is prepared by drying lime slaked with an excess of water. The powder thus obtained constitutes a substantially more effective neutralizing agent for acidic components of flue gas (in particular SO2 and HCl) than ordinary powdered hydrated lime prepared by dry slaking. The drying of the hydrated lime takes place preferably by spray drying. The agent can be applied to flue gas having a temperature which is suitable for the discharge of said gas through the stack. The agent is dispersed in the flue gas and is again separated therefrom preferably by means of a bag filter.
