What is the role of desulfurized magnesium oxide in use

Low operating costs, the most important factor affecting the operating costs of the desulfurization system is the consumption of desulfurizers and water, electricity, and gas. The price of magnesium oxide is higher than that of calcium oxide, but the consumption of removing the same desulfurized magnesium oxide is 40% of calcium carbonate. The liquid-to-gas ratio is an important factor that affects the energy consumption of water, electricity, and gas. It directly affects the desulfurization power of the entire system and the operating cost of the system. Regarding the limestone system, the liquid-to-gas ratio generally exceeds 15L/m3, while the desulfurized magnesium oxide is not higher than 7L/m3, so the desulfurized magnesium oxide process can save most of the cost. Selling magnesium oxide by-products can offset most of the cost. 97 fused magnesia

Reliable operation, the advantage of magnesium desulfurization than calcium desulfurization is that the system does not have the problem of equipment fouling and clogging. Ensure the safe and effective operation of the entire desulfurization system. The pH value of magnesium desulfurization is controlled between 6.0 and 6.5. In this case, the corrosion problem of equipment has also been dealt with to a certain extent. Generally speaking, the safety function of desulfurized magnesium oxide in engineering is very strong.

According to the data history satisfaction, my country's magnesium oxide reserves are very considerable. Magnesium oxide has been found to store about 16 billion tons, accounting for about 80% of the world's total reserves. The resources are mainly distributed in Liaoning, Shandong, Sichuan, Hebei and other provinces, of which Liaoning accounts for 84.7%, followed by Laizhou, Shandong with 10%. Other major areas include Xingtai River in Hebei, Ganluo Salt Belt in Sichuan, Hanyuan in Sichuan, Subei in Gansu, and Biegai. Therefore, desulfurized magnesium oxide can be used as a desulfurizer in power plant desulfurization systems.

High desulfurization power, magnesium oxide is much more active than calcium-based desulfurizers in chemical reactions, and its molecular weight is smaller than calcium carbonate and calcium oxide. Therefore, in the same environment, magnesium oxide is higher than calcium. The ability to desulfurize magnesium oxide can generally reach 95-98%, while the desulfurization rate of limestone is only 90-95%. Low capital cost. Because desulfurization magnesium oxide and desulfurization have the same benefits, the structure design of the absorption tower, the size of the circulating slurry, the overall system planning and the energy consumption of the equipment can be relatively low, so that the capital of the entire desulfurization system Money can drop by more than 20%.
