| Message: | Eco-friendly Mg(OH)2 Fuel Gas Desulfurization Brucite Magnesium Hydroxide With the continuous growth of coal consumption, the sulfur dioxide also surged, which causes serious acid rain and sulfur dioxide pollution. Various countries are also encouraging enterprises to adopt advanced desulfurization and dust removal technologies. In the 1980s, calcium-based desulfurizer was widely used at abroad. Except for the United States, This technique is widely used in other countries and regions. Limestone is easily available, cheap price. The desulfurization rate can reach 90%. However, the disadvantage is also obvious: high Ca/S ratio, low activity of calcium hydroxide, small absorption capacity, high liquid-gas-ratio, cost more in equipment and operation. If not properly treated, it will clog pipelines and the desulfurization gypsum will cause Secondary pollution. Magnesium hydroxide is much higher in Chemical reactivity compared with calcium-based desulfurizer. It is becoming more and more popular nowadays.Advantage of Fuel Gas Desulfurization Brucite Magnesium Hydroxide 1. Higher in efficiencyMagnesium hydroxide is much higher in Chemical reactivity compared with calcium-based desulfurizer; and its molecular weight is smaller than calcium carbonate and calcium oxide. In the same condition, the flue gas desulphurization efficiency of magnesium hydroxide is much higher than calcium-based one. Generally speaking, the desulphurization efficiency of magnesium hydroxide is 95~98%, while the desulphurization efficiency of limestone/parget is only 90~95%.2. Less in investmentsince it is high efficient in flue gas desulphurization, small absorption tower is OK; less circulation size can be used. It will be 20% cost savings for the whole investment.3. Steady operationThere is no scaling since Mg(OH)2 system is adopted. We can control the PH value between 6.0 and 6.5, so that it solves the challenge of equipment corrosion. Magnesium hydroxide in the flue gas desulfurization is hi......url:http://www.magnesiumhydroxides.com |
