Limestone slurry is prepared mixing fine limestone powder with water in a slurry preparation tank. Sorbent slurry from this tank is then pumped into the absorber reaction tank. The absorber is a counter-flow tower with flue gas flowing upwards, while limestone slurry is sprayed downwards by an array of spray nozzles.
