Product name: desulphurization with magnesium hydroxide
Implementation of the standards: HG/T3607--2007
Product name: desulphurization with magnesium hydroxide
Implementation of the standards: HG/T3607--2007
Product brand: Honghai
Molecular formula: Mg (OH) 2
Product specification: 25kg
Molecular weight: 58.32
Appearance: white powder
Bulk density: 2.36g/cm ³
Physical properties: soluble in dilute acids and ammonium salts solution, almost insoluble in water andalcohol. Solubility in water (18 c) for 0.0009g/100g. Easy to absorb carbon dioxide from the air. Heated to200 degrees centigrade in alkaline solution over time-varying crystals into fibers. At 350 ° c decomposesinto magnesium oxide and water. Lose water into magnesium oxide higher than 500 ℃.
Product use: main flue gas desulphurization with magnesium hydroxide, waste gas desulphurization, effectiveadsorption removal of acid gases and meet emission standards.
Product features: 1. high desulfurization efficiency. In terms of Chemical reactivity of magnesium hydroxideis much larger than calcium-based sorbent, and because of the higher molecular weight of magnesiumhydroxide, calcium carbonate and calcium oxide is relatively small. Under the same conditions of magnesiumhydroxide method of desulfurization efficiency desulfurization efficiency higher than calcium. Generalmagnesium hydroxide desulfurization efficiency can reach more than 95-98%, desulfurization efficiency inlimestone-gypsum method only reaches about 90-95%.
2. investment costs low. Due to magnesium hydroxide desulfurization itself has its unique advantages inabsorption tower of structure designing, circulating slurry volume size, the scale of system, equipment ofpower can be less, so that investment costs could be reduced by more than 20% across the desulfurizationsystem.
3. low running cost. Decision FGD system cost sorbents are the main factors of cost and the cost of water,steam. Magnesium hydroxide price higher than the calcium oxide, but the same SO2 removal of magnesium hydroxide calcium carbonate 40%; power consumption such as water, steam, liquid-gas ratio is an importantfactor, it is directly related to the system of desulfurization efficiency and operating cost of the system.Limestone-gypsum systems, liquid-gas ratio in more than 15L/m ³, and magnesium hydroxide to 7 l/m ³, somagnesium hydroxide desulfurization process can save a large portion of the costs. While the sale of by-products of magnesium hydroxide to offset a large portion of the costs.
4. reliable operation. Magnesium-calcium desulphurization in relation to the maximum advantage of systemequipment scaling problem does not occur, to ensure the safe and effective operation of desulfurizationsystem as a whole, and magnesium between 6.0-6.5 PH value control, equipment corrosion in such conditions isto some extent to solve problems. In General, magnesium desulfurization in engineering can have a verystrong security guarantees.
