Magnesium-based desulphurisation technology
Product Details
- Overview
The desulphurisation mechanism of magnesium oxide is similar to that of calcium oxide: in both cases, the alkaline oxide reacts with water to form a hydroxide, which then undergoes an acid-base neutralisation reaction with the sulphurous acid solution formed when sulphur dioxide dissolves in water. The reaction of magnesium oxide produces magnesium sulphite and magnesium sulphate; magnesium sulphite is subsequently oxidised to form magnesium sulphate.
II. Characteristics of the Magnesium-Based Desulphurisation Technology
- Mature technology
- Abundant raw material supply
- High desulphurisation efficiency
- Low capital costs
- Low operating costs
- Reliable operation
III. Scope of Application
In particular, the wet flue gas desulphurisation technology using magnesium oxide is a relatively economical and practical method for the small and medium-sized thermal power sector. It has a wide range of applications and is extensively used in desulphurisation projects within the power industry, metallurgical sintering plant flue gas systems, industrial boilers, and paper mills.
