NaHCO3 SOLVAir®

Pre-ground SOLVAir® Sodium Bicarbonate for Cement Factories

The cement industry faces significant environmental challenges, particularly regarding air emissions during the production process. Cement burning operations release fumes that include sulfur oxides (SOx) and hydrochloric acid (HCl), pollutants that not only reduce air quality but can also affect critical components of purification systems, such as catalytic DeNOx units. The integration of advanced fume treatment solutions is therefore crucial to mitigating these environmental impacts, and pre-ground sodium bicarbonate plays a key role in this context.

Solution with Pre Ground SOLVAir® Sodium Bicarbonate

An efficient approach to flue gas purification in cement plants uses the injection of pre-ground Solvay SOLVAir® sodium bicarbonate, delivered through a doser that regulates the amount. This technique uses these substances in a finely ground form, facilitating rapid dissolution and reaction with the gaseous pollutants present in the flue gases. This process ensures the effective elimination of harmful particles, complying with emissions regulations and preventing corrosion of sensitive components such as catalytic DeNOx units.

FAQ

Primary Pollutants in the Cement Production Process

During cement manufacturing, emissions of primary pollutants such as sulfur oxides (SOx) and hydrochloric acid (HCl) occur. These compounds, stemming from both the raw materials and the reactions required to produce clinker, pose significant environmental challenges for the cement industry.

Why Use Pre-Milled Sodium Bicarbonate?

Cement production involves high-temperature processes that can lead to harmful emissions of SOx and HCl. The use of pre-milled sodium bicarbonate neutralizes these substances, transforming them into harmless saline compounds. This approach ensures effective gas purification, providing enhanced environmental protection.

What are the Differences Between Sodium Carbonate and Sodium Bicarbonate?

Both sodium carbonate and sodium bicarbonate are used to neutralize acids present in flue gases. However, they differ in their mechanism of action. Sodium carbonate has a higher degree of alkalinity, making it more effective against a broader spectrum of acids. On the other hand, sodium bicarbonate reacts with acids to form CO2, water, and an activated sodium carbonate residue. This residue, with its more porous structure, improves efficiency thanks to a larger exposure surface area, which is particularly beneficial at lower temperatures.
