Technical Sodium Bicarbonate and Activated Carbon/Lignite Coke for Gas fired Power Plants

Natural gas power plants are a key element in the transition to a more sustainable energy mix, playing a crucial role in meeting growing energy demand. However, while generally considered cleaner than coal-fired plants, gas-fired plants can also release harmful pollutants, such as sulfur (SOx), as well as traces of heavy metals and other chemical compounds during the combustion process. To minimize their environmental impact, these plants adopt advanced flue gas purification technologies.

One of the most effective solutions involves the combined use of technical sodium bicarbonate and activated carbon or lignite coke. Technical sodium bicarbonate is used to neutralize acids, while activated carbon and lignite coke capture heavy metals and volatile organic compounds present in the flue gases.

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

Flue gas treatment in gas-fired power plants involves a two-stage process: first, the flue gas is treated with finely ground technical sodium bicarbonate and distributed through the filter system to neutralize acids. Subsequently, activated carbon or lignite coke is injected through a special doser to absorb remaining pollutants, such as heavy metals and organic compounds.

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

FAQ

What pollutants are present in the flue gases of gas power plants?

Although gas power plants are considered cleaner, they can still release pollutants such as sulfur oxides (SOx), as well as traces of heavy metals like mercury (Hg), and volatile organic compounds. These pollutants can have harmful effects on the environment and human health, making flue gas treatment systems essential.

Why use technical grade sodium bicarbonate and activated carbon/lignite coke in flue gas treatment at gas power plants?

During the combustion of natural gas, pollutants such as sulfur oxides (SOx), in addition to traces of heavy metals, are produced. Flue gas cleaning systems must reduce these pollutants to comply with environmental regulations and to protect public health. Technical grade sodium bicarbonate effectively neutralizes the acidic component of exhaust gases, while activated carbon/lignite coke removes hazardous substances like heavy metals.

How does sodium bicarbonate work in flue gas treatment?

Sodium bicarbonate acts as a neutralizer for the acids in the flue gases, such as sulfur oxides (SOx), converting them into less harmful and soluble compounds that can be easily removed from the exhaust stream.

How do activated carbon and lignite coke work in flue gas treatment?

Activated carbon and lignite coke, thanks to their extensive surface area and porosity, effectively absorb specific pollutants such as heavy metals and volatile organic compounds, trapping them in their pores and removing them from the exhaust gas flow.

When is it preferable to use activated carbon over lignite coke?

Both applied in flue gas cleaning, activated carbon is superior due to its ability to effectively adsorb various contaminants, utilizing an optimal porous structure. Lignite coke, on the other hand, is especially suitable for low-temperature operations, where it performs well at a more contained price, making it ideal for specific operational regimes.
