Technical points of magnesium oxide desulfurization process
1. Mature technology.
Magnesium oxide desulfurization technology is a desulfurization process whose maturity is second only to calcium method. Magnesium oxide desulfurization technology has a lot of application achievements all over the world. Among them, more than 100 projects have been applied in Japan, and 95% of power stations in Taiwan are Magnesium oxide method has been applied in the United States, Germany and other places, and has already been applied in some areas of our country.
2. Sufficient source of raw materials.
The reserves of magnesium oxide in my country are considerable, and the proven reserves of magnesium oxide are about 16 billion tons, accounting for about 80% of the world's total. The construction industry is used in the manufacture of artificial chemical floors, artificial marble heat-proof panels and sound-proof panels, and as fillers in the plastic industry. Its resources are mainly distributed in Liaoning, Shandong, Sichuan, Hebei and other provinces, of which Liaoning accounts for 84.7% of the total, followed by Laizhou, Shandong, accounting for 10% of the total, and the rest are mainly in Xingtai River, Hebei, Ganluoyandai, Sichuan, Hanyuan, Subei, Biegai and other places in Gansu. Therefore, magnesium oxide can be used as a desulfurizer in the desulfurization system of power plants.
3. Desulfurization.
In terms of chemical reaction activity, magnesium oxide is far greater than calcium-based desulfurizers, and the molecular weight of magnesium oxide is smaller than that of calcium carbonate and calcium oxide. The reserves of magnesium oxide in my country are considerable, and the proven reserves of magnesium oxide are about 16 billion tons, accounting for about 80% of the world's total. Therefore, the desulfurization efficiency of magnesium oxide is higher than that of calcium method under the same other conditions. Under normal circumstances, the desulfurization efficiency of magnesium oxide can reach more than 95~98%, while the desulfurization efficiency of limestone/gypsum method only reaches about 90~95%.
