Magnesium oxide desulfurization technology is a desulfurization process that ranks second only to the calcium method in terms of maturity. The magnesium oxide desulfurization process has been applied in many projects around the world, with over 100 projects in Japan alone. In Taiwan, 95% of power plants use the magnesium oxide method. Additionally, it has been applied in places like the United States and Germany, and there are already records of successful applications in some regions of China.
