Abstract:Although the organic amine desulphurization technology can optimize the environmental protection index, it still has some defects in treating the flue gas in the fire method. A series of innovative technical measures have been taken, such as automatic acid mist dehumidification technology and cloth bag dust collecting and fire control spray technology, the application of efficient spray purification technology, the application of new technology, the reduction of regenerated steam consumption, etc. to reduce the concentration of SO2 in the tail exhaust.
