Technical Sodium Bicarbonate and Activated Carbon/Lignite Coke for Steel Plants

In the steel industry, the production of steel and iron generates considerable amounts of harmful fumes and vapors resulting from metal processing. These fumes contain environmentally hazardous substances, such as SOx, HCl, and heavy metals (Zn, Pb, Cr), which must be effectively treated to minimize their environmental impact. To combat these harmful emissions, the industry uses fume purification systems that employ, among other things, technical sodium bicarbonate and activated carbon or lignite coke.

Solution with Technical Grade Sodium Bicarbonate plus Active Carbon or Lignite Coke

The approach proposes the adoption of an advanced two-stage filtration system, with the primary objective of neutralizing acids and capturing heavy metals and volatile organic pollutants (VOCs). The strategy involves the use of a treatment plant that distributes technical sodium bicarbonate and then activated carbon or lignite coke in the exhaust gases generated during the steelmaking process.

Flue Gas Cleaning with Technical Grade Sodium Bicarbonate and Active Carbon or Lignite Coke

FAQ

What pollutants are typically present in the fumes from the steel industry?

During the production of steel and iron, various pollutants are emitted. Metallurgical processing and the use of fossil fuels generate sulfur oxides (SOx), as well as hydrochloric acid (HCl). Heavy metals such as Zinc (Zn), Lead (Pb), and Chromium (Cr) are also commonly present, along with various volatile organic compounds, representing a significant environmental challenge.

Why use technical grade sodium bicarbonate and activated carbon/lignite coke for flue gas purification in the steel industry?

The steel industry, in its production process, generates polluting fumes containing acids such as sulfur oxides (SOx), hydrochloric acid (HCl), as well as heavy metals (Zn, Pb, Cr), and other hazardous volatile organic compounds. Sodium bicarbonate neutralizes the acids present, converting them into harmless salts, while activated carbon/lignite coke is effective in absorbing heavy metals and organic compounds, significantly reducing the environmental impact of the fumes.

How does sodium bicarbonate work in the flue gas purification process?

Within the steelmaking context, sodium bicarbonate reacts with the acids contained in the fumes, for example, HCl and SOx, converting them into harmless salts such as sodium chloride and sodium sulfate. This chemical reaction also occurs at high temperatures, typical of industrial processes, contributing to the reduction of the overall acidity of the fumes.

What is the role of activated carbon and lignite coke in flue gas treatment?

Activated carbon and lignite coke play a critical role in absorbing heavy metals such as Zinc, Lead, and Chromium, as well as volatile organic compounds and other toxic substances present in the metal processing fumes.

How do lignite coke and activated carbon differ in removing atmospheric pollutants?

The use of lignite coke and activated carbon in the removal of atmospheric pollutants is based on their distinct filtration capabilities. Activated carbon, known for its vast surface area and porous structure, is particularly effective in capturing a variety of gases and organic vapors, making it ideal for a wide range of applications. Lignite coke, on the other hand, proves advantageous in specific contexts where temperatures do not exceed 200°C, specializing in the removal of particular contaminants. Due to its lower cost, lignite coke is preferable in thermally compatible environments.
