Energy Requirements of a Limestone FGD System

the performance of current limestone systems.2 Energy is needed in the scrubbing process to pump slurry through the scrubber circuit and to drive the fans needed to overcome gas phase pressure drops through the SO2 absorber vessel and associated ductwork. Pumping power is a function of liquid flow and pressure drop, dependent on contactor design.
