Clairion™ Technology Overview

Clarion offers a completely new approach for the removal of pollutants (such as NOx, SOx and Hg) from flue gas. This eco-friendly technology, unlike most of the existing technologies, is based on a wet absorption process that utilizes a unique liquid formulation circulated within a scrubber in a closed loop with the minimal use of raw materials.


Unique liquid formulation

Clairion’s unique liquid formulation is comprised of modified ionic liquids and oxidizers and forms the basis of the C-HgR™ and C-MPR™ solutions.

Ionic liquids are salts in a liquid state which have unique physical properties, such as low or non-volatility and exclusive complex properties, high thermal stability, and immeasurable vapor pressure.


Closed cycle

Unlike other processes, our process ensures the absorption liquid operates in a “closed cycle” in which the flue gas impurities are captured and concentrated within the liquid as a stable complex.

Our unique wet scrubber was designed for swift and effective oxidative absorption of the emitted pollutants. The highly stable composite liquid which exhibits zero vapor pressure is contacted with the flue gas. This results in a rapid oxidation/absorption of the pollutants followed by a complex formation and absorption in the ionic liquid.


Removes all forms of pollutants

Our technology removes all forms of pollutants, including SO2, NOx and mercury – demonstrating exceptional SO2, mercury and sulfur removal rates (extraordinary compared to other existing technologies) along with significant environmental and financial benefits.


Selective extraction

Another advantage of our technology is the selective extraction – the superior absorption liquid allows us to run a multi-stage extraction process. At each stage, the necessary ingredient can be easily separated from the mixture. With our unique process, concentrated sulfuric acid and concentrated nitric acid can be produced in aqua phase, while all forms of mercury remain in the absorption liquid and can be stabilized and then removed by an additional side process.
