SOLVAir®

A dry solvent injection process for air emission control

Identification

SOLVAir® is a highly efficient flue gas-cleaning solution using Sodium-Based Sorbent for Air Pollution Control by dry injection.

Effective and simple, the SOLVAir® sodium-based solutions is a dry sorbent injection process for air emission control. When in contact with flue gases, it effectively neutralizes the acids to mitigate pollutants. The acid neutralization reaction begins as soon as the sodium-based solution is in contact with the acid gases. With a bag filter, the sodium bicarbonate forms a homogeneous layer on the whole filtrating surface (filtration cake). This allows for the efficient neutralization of the acid gases while complying with the strictest emission limits and optimizing sorbent consumption. Thanks to its thermal activation, the milled sodium-based product succeeds in achieving the highest abatement rates of acids with a very low excess. This result is achieved by a fully dry system, with a silo, an injection system and a filter as equipment.
