Nitrogen Removal
Nitrogen is a common are among common contaminants in process streams from biomass and solid waste gasification. The nitrogen content in biomass and other waste feedstocks varies widely by the feedstock source. Nitrogen-containing syngas contaminants include amines, amides, and nitriles, all of which may cause operational and environmental issues during and after gasification. Nitrogen compounds are also known to be very stable. The most common types of nitrogen in biomass and waste gasification are ammonia (NH3) and hydrogen cyanide (HCN), which are the precursors of nitrogen oxide emissions (NOx) in downstream burners, gas engines, or gas turbines.
AN-XD
Active Component: MgO
Form: Sphere
Advanced formulation that allows for high removal efficiencies at optimal process conditions. Normally used at temperatures of 200-300 С in non regenerable service.
AN-ED
Active Component: CuO-AlOx
Form: Extrudate
Mixed metal oxide type formulation. High robustness media utilized at process temperatures about 350 C and tolerant to multiple side contaminants in the stream.
