The study looked at how to make wet lime-limestone-gypsum flue gas desulfurization systems more effective. They tested different factors to see which ones had the biggest impact on removing sulfur. By creating a model, they could predict how well the system would work based on its design and settings. They also figured out how the color of the materials used affected the quality of the gypsum produced. The researchers found out which factors influenced the size and shape of the gypsum crystals. They developed a model to show how changing certain settings affected the amount of calcium carbonate in the gypsum.
