Why use limestone for desulfurization? Limestonecan be used in desulfurizationand has a good effect. The greatest significance of desulfurization is to reduce acid rain by reducing sulfur dioxide emissions, and it can also contribute to reducing air pollution. What are the requirements for limestone powder for desulfurization?

The limestone wet flue gas desulfurization process is generally operated under the condition of a pH value of less than 6.2, which can increase the solubility of limestone. When the pH value is between 5.5 and 6.0, most of the SO2 absorbed by the circulating slurry exists in the form of HSO3- and cannot be combined with H+.

In order to eliminate the SO 2, the flue exhaust gases from a coal-fired power plant are usually passed through a spray of limestone slurry in the scrubber.

Wet Lime FGD. The process of wet scrubbing typically utilizes an alkaline-based slurry of lime to scrub gases.
