Abstract:
A wet-type flue gas desulfurization plant for removing sulfur oxides from an exhaust gas, said apparatus comprising:contact means for contacting the exhaust gas with water-containing absorbent in an absorbing zone to absorb the sulfur oxides and thereby form an acidic water-containing liquid;neutralization means, including a bed of desulfurizing agent particles within a neutralizations zone, for contacting the acidic water-containing liquid with the desulfurizing agent particles to regenerate the water-containing absorbent, the particles of said desulfurizing agent having a weight average particle diameter of at least 0.5 mm;recirculating means for recirculating at least one portion of the regenerated water-containing absorbent, separated from the desulfurizing agent particles, to the absorbing zone for use in said contacting while leaving the desulfurizing agent particles within said neutralizing zone.
