Technical Sodium Bicarbonate for Biomass Waste to Energy Incineration Plant

Biomass waste-to-energy is an increasingly popular process in the energy sector for converting organic material into electricity and heat. Although considered a more sustainable alternative to coal combustion, this process also emits potentially harmful gases, particularly sulfur oxides (SOx), hydrochloric acid (HCl), hydrofluoric acid (HF), and other air pollutants that must be filtered before the fumes are released into the environment. One of the most effective methods is the use of alkaline chemical reagents such as sodium bicarbonate and, depending on the type of pollutant, activated carbon or lignite coke.

Solution with Technical Grade Sodium Bicarbonate

The solution to effectively treat the flue gases produced during biomass incineration is the use of technical sodium bicarbonate. Using a dedicated mill system that pulverizes and finely injects the sodium bicarbonate into the flue gas stream, it neutralizes the acidic compounds present in the flue gas, producing inert salts that can be easily removed from the flue gas stream.

Active Carbon or Lignite Coke

Depending on the type of biomass being incinerated, other pollutants, such as heavy metals, may be released. In this case, the solution to reducing polluting emissions must be integrated with a second filtering station featuring an activated carbon or lignite coke doser, which, with its properties, binds to heavy metals and prevents their release into the environment.
