Flue gas desulfurization - Lenntech
Typical SO 2 removal processes are wet scrubbing and dry scrubbing. In wet scrubbing systems, the ones mostly used, the fly ash is removed first by an electrostatic precipitator (ESP), then the flue gas passes into the SO 2 absorber. Electrostatic precipitator performance is often enhanced by adding ammonia to the flue gas.
