The quality of limestone is determined by the content of CaO, and the higher the purity of limestone, the better the desulfurization efficiency. But limestone does not necessarily have a higher CaO content. Limestone with CaO>54% is not suitable as a desulfurizer due to its high purity, difficulty in grinding, and strong chemical stability. 2.

Wet flue gas desulfurization was simulated to improve gypsum production using low-grade limestone. High-grade limestone with 94 wt% CaCO 3 content is used for producing gypsum with 93 wt% purity, but owing to the resource depletion of high-grade limestone, low-grade limestone should be replaced as an alternative. However, low …
