The process can be applied in a mobile regeneration plant operating directly on-site. Therefore, no catalyst transport is necessary at all, thus reducing the downtime of the plant to a minimum. In combination with our sophisticated catalyst management, the operating costs and maintenance expense can be reduced even more.
The Yara catalyst rejuvenation technology comprises the patents and the proprietary knowledge of Yara for aqueous-based on-site rejuvenation technology.
Yara covers methods of rejuvenating the performance of used SCR catalysts from deactivation mechanisms that have occurred in use, including but not limited to blockage by ash including large popcorn ash, blockage by unburned carbon, blockage by ammonium bisulfate, deactivation by alkali metal and alkaline earth compounds, and deactivation by other metal compounds.
The physical form of the SCR catalysts can be any of the commercially available types such as honeycomb, plate and the like.
