Magnesium oxide desulfurization method has several advantages. Magnesium oxide is used for desulfurization. Mature technology Magnesium oxide desulfurization technology is a kind of desulfurization technology 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. 95% of Taiwan's power plants are made of magnesium oxide and magnesium oxide is used for desulfurization. In addition, Magnesium oxide has been applied in the United States, Germany and other places, and it has been applied in some parts of China at present. Performance. Adequate sources of raw materials Magnesium oxide reserves in China are considerable. At present, the proven reserves of magnesium oxide are about 16 billion tons, accounting for about 80% of the world. 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 Province, accounting for 10% of the total. The others are mainly in Xingtai River, Ganluo Yandai, Hanyuan, Subei, Biegai and other places in Hebei Province. Therefore, magnesium oxide can be used as desulfurizer in power plant desulfurization system. High desulfurization efficiency Magnesium oxide is much more active than calcium-based desulfurizer in chemical reaction, and its molecular weight is smaller than that of calcium carbonate and calcium oxide. Therefore, the desulfurization efficiency of magnesium oxide is higher than that of calcium method under the same other conditions. Generally, the desulfurization efficiency of magnesium oxide can reach 95-98%, while the desulfurization efficiency of limestone/gypsum method can only reach 90-95%. Less investment costs Magnesium oxide as desulfurization has its own unique advantages, so the structure design of absorption tower, the size of circulating slurry, the overall scale of the system and the power of the equipment can be relatively small, so that the investment cost of the whole desulfurization system can be reduced by more than 20%. Low operating costs The main factors determining the operation cost of desulfurization system are the consumption cost of desulfurizer and water, electricity and steam. The price of magnesium oxide is higher than that of calcium oxide, but the consumption of removing the same SO2 magnesium oxide is 40% of calcium carbonate. The liquid-gas ratio is a very important factor in power consumption, such as water, electricity and steam, which directly affects the desulfurization efficiency of the whole system and the operation cost of the system. For the limestone gypsum system, the liquid-gas ratio is generally above 15L/m3, while the magnesia is below 7L/m3, so the magnesia desulfurization process can save a lot of costs. At the same time, the sale of magnesium oxide by-products can offset a large part of the cost. Reliable operation The greatest advantage of magnesium desulfurization over calcium desulfurization is that the system will not cause fouling and blockage of equipment, and can ensure the safe and effective operation of the whole desulfurization system. At the same time, the PH value of magnesium desulfurization is controlled between 6.0 and 6.5. Under this condition, the corrosion problem of equipment has also been solved to a certain extent. Generally speaking, the safety performance of magnesium desulfurization in practical projects has a very strong guarantee.
