Limestone flue gas desulphurization systems (FGDs) are wellproven and costeffective. They have been in use in power stations since the 1970s. Over the years, we have created an advanced scrubber design with outstanding reliability and excellent availability. Plant economics have also been optimized, ensuring low capital and operating costs.
Usually the plant is loed downstream of the electrostatic precipitator (ESP) so that most of the fly ash generated from combustion is removed before the gas reaches the FGD plant. In the process of desulphurization the gas is scrubbed with a recirculating limestone slurry, which removes almost 95% of the SO 2 from the flue gas.
· The ANDRITZ scope of supply includes the plant's complete basic engineering as well as detailed engineering for the absorber and other critical supplies. Limestone flue gas desulphurization systems are wellproven and costeffective and have been used in power stations since the 1970s to convert the main acid gas SO2 into gypsum.
