Pre-ground SOLVAir® Sodium Bicarbonate and Active Carbon or Lignite Coke for Paper Mill Pulper Waste to Energy Incineration Plants

In the waste management sector, waste-to-energy plants for paper pulp waste play a crucial role in reducing waste volumes by converting it into energy. While this solution helps reduce the environmental impact of paper waste, the combustion process releases flue gases containing hazardous pollutants such as sulfur oxides (SOx), hydrochloric acid (HCl), hydrofluoric acid (HF), and heavy metals such as mercury, lead, and cadmium. The presence of these compounds requires the adoption of advanced technologies to ensure emissions remain within the limits established by environmental regulations. An effective flue gas treatment method uses a combination of Solvay SOLVAir® pre-ground sodium bicarbonate and activated carbon or lignite coke.

Solution with Pre Ground SOLVAir® Sodium Bicarbonate plus Active Carbon or Lignite Coke

Using Solvay SOLVAir® pre-ground sodium bicarbonate, acids in the flue gas can be chemically neutralized, converting them into non-volatile, environmentally safe salts. Simultaneously, activated carbon or lignite coke is injected to effectively adsorb heavy metals and other toxic substances released during combustion. This combination of additives is carefully dosed through two separate injection systems, optimizing process efficiency and ensuring compliance with current environmental standards without compromising plant efficiency.

Flue Gas Cleaning with Pre-ground Solvay SOLVAir® Sodium Bicarbonate and Active Carbon or Lignite Coke

FAQ

What are the main pollutants during the combustion of pulper waste in waste-to-energy plants?

The main pollutants include SOx, HCl, HF, and heavy metals such as mercury, lead, and cadmium, which need to be treated to minimize environmental and health damage.

Why are pre-milled sodium bicarbonate and activated carbon/lignite coke used in the flue gas treatment of waste-to-energy plants?

During the combustion of pulper waste, pollutants such as SOx, HCl, HF, and heavy metals are formed. Pre-milled sodium bicarbonate neutralizes these acids by transforming them into salts. Activated carbon/lignite coke captures and removes heavy metals and other harmful compounds.

What is the purpose of sodium bicarbonate in the flue gas treatment of waste-to-energy plants?

Sodium bicarbonate reacts with acids like SOx, HCl, and HF present in the flue gases, converting them into stable solid salts, thereby reducing the environmental impact of harmful emissions.

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

These adsorbent materials are essential for the removal of heavy metals and hazardous organic compounds thanks to their high porous adsorption surface area, ensuring an effective flue gas purification.

Are activated carbon and lignite coke interchangeable?

Both are useful for flue gas purification, but they differ in adsorption capacity. Activated carbon is generally more effective due to its higher porosity, while lignite coke may be preferred for specific applications, especially those at lower temperatures, due to reduced costs.

Differences between the use of sodium carbonate and sodium bicarbonate?

Sodium Carbonate and Sodium Bicarbonate are both employed to counteract the acids in industrial exhaust gases, but their modes of action differ. Sodium Carbonate is more alkaline and efficiently neutralizes various types of acids. On the other hand, Sodium Bicarbonate decomposes, releasing CO2, water, and a more porous version of Sodium Carbonate, which shows greater effectiveness at lower temperatures, thus being particularly useful in the steel industry.
