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 efficiency
Magnesium 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 investment
since 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 operation
There 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 high effective, continuous, safe, reliable, economical, and derivatives can be recycled.
4. Lower operating cost
For the Flue Gas Desulfurization, desulfurizer and utilities will be the key point. The consumption of magnesium hydroxide is around 40% of CaCO3 for removing same quantity SO2. The liquid-gas-ratio is of great significance while comparing the utilities. Moreover, the by product can be sold when use Mg(OH)2 system.
Application of Fuel Gas Desulfurization Brucite Magnesium Hydroxide:
It is mainly used in coal-fired power plants or municipal waste incineration for mercury removal, desulphurization and dust removal. Eliminating mercury vapor, and sulfur dioxide and other toxic and harmful gases, and won’t cause secondary pollution. It can also be used as antacid. It is used as a kind of "green and safety" neutralizer in environmental engineering. Flue gas desulfurization process includes dust removal and desulfurization, mercury removal and etc.
