A completely new approach for simultaneous removal of NOx, SOx and Hg from flue gas. Unlike most existing solutions, this patented technology enables an absorption/extraction process as a single solution treating all three pollutants.
The C-MPR™ technology was developed in order to comply with the new emissions limits at a lower cost utilizing a smaller operation area compared to the current used combination of traditional single pollutant control systems.
Unlike other process, the C-MPR™ utilizes a proprietary absorption liquid formulation (based on modified ionic-liquids and oxidizers) implemented in a wet scrubber. The NOx, SOx and Hg contained in flue gas stream react with an oxidizing agent in order to form soluble elements that enter the scrubber. The unique absorbing liquid is constantly circulated within the scrubber in a “closed cycle” in which the flue gas impurities are captured as a stable complex.
In the next phase of the process the absorbed impurities are extracted into aqua phase via a mixture settler to form useful products with high commercial value such as fertilizers or concentrated acids.
The absorbing liquid’s unique physical properties and the system’s engineering design assures no liquid is being emitted to the environment.
Another advantage of this technology is the selective extraction ability. The superior absorption liquid allows to run a multi-stage extraction process. At each stage a specific pollutant is easily separated from the mixture. In such unique process a 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 removed by a side process while the liquid is regenerated for reuse.
The system removes all mentioned pollutants, demonstrating exceptional removal rates of NOx (above 85%), SO2 (above 90%) and Hg (above 95%) along with significant environmental and financial benefits. This new approach offers a dramatic change from both economic and environmental perspectives compared to existing used technologies.
The system, which can be custom-made and installed as a retrofit, is a scalable solution and therefore applicable to a wide range of industries, plants and processes.
A novel approach innovating the way mercury (Hg) is removed from industrial gas emissions.
Elemental mercury is extremely difficult to remove due to its absorbing characteristics and current commonly applied solutions suffer from clear known disadvantages and inefficiencies:
Limited removal efficiency which varies and depends on gas conditions and combination of installed APCs, Intensive usage of consumable adsorbents, Impact on properties of byproduct – limiting their sales / re-use, Disposal/Recycling costs of the contaminated byproducts and absorbents, Damage to infrastructure due to corrosivity of chemical additives, Hg is redistributed and re-emitted to the environment with the by-products created throughout the process and the environmental contamination by Hg is not really avoided
Clairion is addressing these challenges with its C-HgR™ – – an innovative proprietary absorption process using a unique liquid formulation of modified ionic liquids and oxidant agents implemented in a wet scrubber. The flue gas stream contaminated with the mercury particles enters the scrubber in which the unique liquid is constantly circulated. The chemical reaction in which the mercury is simultaneously oxidized and captured in the liquid as a stable complex occurs within the device.
In a separate process, the liquid is then regenerated through a simple process in which the mercury is transferred into an insoluble stable form (HgS) that can then be safely disposed, while the absorbent liquid is regenerated for re-use. This can be done periodically (months to years) as a service off-site or continuously on-site as an integrated process (depending on sites characteristics and customer’s needs
The offered approach and structure enable a highly efficient chemical reaction and short contact time between the flue gas and liquid. The system removes all mercury forms, including elemental mercury – demonstrating exceptional mercury removal rates of > 95% along with significant environmental and financial benefits.
C-HgR™ offers a dramatic change from an environmental perspective. Due the unique engineering design and properties of the absorbing liquid, the process is closed and fully regenerative. The stable complex prevents the problem of evaporation of the oxidizers and mercury reemission and successfully deals with vapor pressure and runaway of liquid droplets. Besides the small quantities of HgS that are safely disposed there are no other contaminated byproducts that need to be handled.
