Magnesium hydroxide desulfurization technology: innovative application in the field of environmental protection

In the field of environmental protection, magnesium hydroxide desulfurization technology is gradually becoming the preferred solution for industrial flue gas desulfurization. This technology is not only favored for its high efficiency and environmental friendliness, but also because the byproducts produced during the desulfurization process can be recycled, further promoting the development of the circular economy. This article will explore the application status of magnesium hydroxide desulfurization technology and its innovation potential in the field of environmental protection.

Overview of magnesium hydroxide desulfurization technology

Magnesium hydroxide desulfurization technology is a wet desulfurization process that uses magnesium hydroxide (Mg(OH)2) to react with sulfur dioxide (SO2) in flue gas to produce magnesium sulfite (MgSO3) and water (H2O). Subsequently, magnesium sulfite is oxidized to magnesium sulfate (MgSO4). This process not only effectively removes SO2 from the flue gas, but also produces resource-based byproducts.

Technical advantages and applications

Efficient desulfurization performance: The desulfurization efficiency of magnesium hydroxide can reach more than 95-98%, which is much higher than the traditional limestone/gypsum desulfurization efficiency, the latter of which is usually around 90-95%.

Resource-based byproducts: Magnesium sulfate produced during the desulfurization process can be used in many fields such as agricultural fertilizers, building materials, animal husbandry and process industries, realizing the resource utilization of waste.

Environmentally friendly: Magnesium hydroxide desulfurization technology does not produce harmful byproducts and is an environmentally friendly desulfurization method. In addition, this technology does not cause equipment scaling and clogging during operation, ensuring the safe and effective operation of the system.

Technical challenges and optimization

Although magnesium hydroxide desulfurization technology has many advantages, it still faces some challenges in practical applications, such as low solubility and easy deposition of magnesium hydroxide. In order to overcome these challenges, researchers are optimizing the technology, including improving the preparation process of desulfurizers, improving desulfurization efficiency and reducing operating costs.

Magnesium hydroxide desulfurization technology, as an environmentally friendly and efficient flue gas desulfurization method, has received widespread attention and application worldwide. With the continuous optimization and innovation of technology, this technology is expected to play a greater role in the future environmental protection field and provide strong support for the realization of green and sustainable development. At the same time, the resource utilization of byproducts will further promote the development of the circular economy and bring new growth points to the environmental protection industry.
