From the analysis above, it can be deduced that the desulfurization process by using low-grade limestone as SO 2 absorbent is divided into three stages: (1) SO 2 dissolves into LGL slurry firstly followed by the formation of SO 3 2−, HSO 3 − and H 2 SO 3 species [21]; (2) continuous dissolution of Ca-based compound including CaCO 3 and CaMg ...
Given potential market demand for desulphurized limestone in Xinjian, SBM has developed some necessary crushers used in desulfurization system including the special desulfurization crusher, special limestone desulfurization crusher, slaked lime desulfurization crusher, which are popular among desulfurization systems of fire power plants.
Compared with limestone-based wet flue gas desulfurization (WFGD), magnesia-based WFGD has many advantages, but it is not popular in China, due to the lack of good wastewater treatment schemes.
Keywords: Flue Gas Desulfurization, FGD sytem design, SO 2 removal, limestone scrubbing, flue gases 1. Introduction 1The term flue gas desulfurization has traditionally referred to wet scrubbers that remove sulphur dioxide (SO 2) emissions from large boilers (mainly coal and oil fired combustion). However, because of the
A schematic of the desulfurization test method using the fluidized bed reactor is shown in Figure 5. Desulfurization limestone was pulverized into powder with a particle size of 0.2–0.4 mm using a pulverizer. This limestone powder was mixed with binding materials and processed into Ca-based desulfurization sorbents.
Limestone–gypsum wet flue gas desulfurization (WFGD) is the most effective desulfurization technique. However, to achieve ultralow SO2 emissions, the efficiency of WFGD should be improved and ...
