SDS(Dry Desulfurization)
Dry desulfurization is to utilize the reducibility and flammability of SO2, using solid oxidant or adsorbent to desulfurize, or directly make it burn. Dry desulfurization is a method to produce Na2SO4 by the reaction of NaHCO3 and SO2, which is called dry desulfurization.
CFB(Semi-Dry Desulfurization)
Semi dry desulfurization technology is a simple, low investment, high performance desulfurization system, covering a small area, easy to access. The process is mainly used in power plant boiler flue gas desulfurization. The flue gas treatment capacity of single tower can be applied to boilers with evaporation capacity of 75t / H ~ 1025t / h, and the SO2 removal rate can reach 90% ~ 98%. It is a method with the largest single tower treatment capacity and the most superior comprehensive desulfurization benefits among the dry and semi dry desulfurization technologies.
WET Desulfurization
Lime / gypsum desulfurization process is a kind of wet desulfurization, which uses limestone, lime or dolomite as desulfurization absorbent to remove SO2 in waste gas. Limestone is widely used and is one of the earliest sorbents for flue gas desulfurization. It is the most widely used and most mature standard desulfurization technology in the world.
