introduction

With the acceleration of global industrialization, environmental protection requirements in steel production are becoming increasingly stringent, especially the emission control of sulfides in flue gas. As an effective environmentally friendly material, ammonium sulfate plays an important role in the desulfurization process of steel. This article will explore its application and advantages in this field.

Basic properties of ammonium sulfate

Ammonium sulfate is an inorganic salt with good water solubility and nutrients, and is widely used in fertilizers, chemicals, metallurgy and other fields. Its chemical formula is (NH4)2SO4. It is not only a necessary material for workshops, but also can effectively reduce harmful gases emitted during the production process.

Necessity of desulfurization of steel

During the steel production process, the combustion of ore and coke will emit a large amount of sulfur dioxide and other sulfides, which not only pollutes the environment but also affects the quality of steel products. Therefore, the application of desulfurization technology has become an urgent need in the industry.

Application of ammonium sulfate in steel desulfurization

The main application of ammonium sulfate in steel desulfurization is to convert sulfur dioxide into other harmless substances through chemical reactions. The reaction equation can be expressed as:

SO2 + 2 NH4OH → (NH4)2SO3 + H2O

This reaction can not only effectively reduce the sulfur dioxide concentration in the flue gas, but the generated ammonia water can also be used as raw material for subsequent processes, forming a good resource recycling system.

Technical advantages of ammonium sulfate

1. Efficient desulfurization : Ammonium sulfate shows excellent reactivity in the desulfurization process and can quickly reduce the SO2 content in the gas.

2. Cost-effectiveness : As a relatively economical chemical, the use of ammonium sulfate in desulfurization technology can effectively save production costs.

3. Environmental protection characteristics : The use of ammonium sulfate can significantly reduce sulfur dioxide emissions, meet international environmental standards, and help enterprises achieve green transformation.

Case Study

In a desulfurization project of a large steel company, after using ammonium sulfate, the emission of sulfur dioxide was reduced by about 60% compared with before, and the production efficiency was significantly improved. This case proves the effectiveness of ammonium sulfate in achieving desulfurization effect.

Summarize

The application of ammonium sulfate in steel desulfurization has gradually become an industry benchmark. With the continuous development of technology in the future, its position in the steel industry will become more and more important. Enterprises should pay attention to the innovation and promotion of this technology in order to maintain competitiveness under strict environmental regulations.
