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.
