Brucite powder production and waste liquid flue gas desulfurization application: a combination of environmental protection and efficiency
Brucite powder, also known as magnesium hydroxide, has a wide range of applications in the industrial field due to its excellent chemical properties. This article will explore the production process of brucite powder and how to effectively use the waste liquid generated in its production process for flue gas desulfurization to achieve the dual goals of environmental protection and resource recycling.
Brucite powder production technology
Chemical precipitation method: Magnesium hydroxide precipitate is generated by the reaction of magnesium chloride and sodium hydroxide.
Process flow: including raw material preparation, precipitation reaction, filtration washing, drying and other steps.
Product advantages: high purity, fine particle size, good thermal stability and chemical stability.
Flue gas desulfurization application of waste liquid
Desulfurization principle: Use alkaline substances in waste liquid to neutralize acidic substances in flue gas, such as SO₂.
Application method: Spray the waste liquid rich in alkaline substances into the desulfurization tower to react with SO₂ to generate sulfate or sulfite.
Technical advantages: Reduce waste emissions, reduce desulfurization costs, and promote the sustainability of industrial production.
Environmental protection and resource recycling
Waste liquid treatment: further treat the waste liquid after desulfurization to recover useful components.
Resource recovery: recover sulfate through crystallization or evaporation concentration to achieve resource recycling.
The application of waste liquid generated during the production of brucite powder in flue gas desulfurization not only improves the utilization efficiency of resources, but also helps environmental protection. With the strengthening of environmental protection regulations, this environmental protection technology of comprehensive utilization of waste liquid will receive more and more attention.
