Pre-ground SOLVAir® Sodium Bicarbonate and Active Carbon or Lignite Coke for Gas fired Power Plants

In the energy sector, gas-fired power plants are a key source of electricity generation. Although these plants are considered cleaner than others that use solid or liquid fuels, they still produce polluting emissions when burning fossil gas. The resulting flue gases contain harmful substances such as sulfur oxides (SOx), hydrochloric acid (HCl), hydrofluoric acid (HF), and heavy metals such as mercury, lead, and cadmium, which can have a significant impact on the environment and human health. To ensure these emissions are kept within the limits permitted by current regulations, advanced flue gas purification systems must be implemented. A particularly efficient solution is the combined use 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

Solvay SOLVAir® pre-ground sodium bicarbonate plays a key role in flue gas treatment, chemically reacting with the acids present to neutralize them and transform them into solid salts, while activated carbon and lignite coke, thanks to their high adsorption capacity, effectively remove heavy metals and other harmful substances present in flue gases. The operating process involves the controlled injection of pre-ground sodium bicarbonate and activated carbon or lignite coke through two separate, calibrated dosers to ensure precise dosing of both materials. This approach achieves high efficiency in the pollutant removal process, while complying with environmental regulations.
