The SO2, NOx Adsorption Process (SNAP) is a dry combined SO2 and NOx removal process using a regenerable sorbent. The only products from SNAP is nitrogen and sulfur. Removal of SO2 and NOx from the flue gas is performed in the riser type adsorber. The regenerable sorbent is composed of a high surface area ?-alumina impregnated with sodium. Regeneration of the sorbent include heating the sorbent to approximately 600°C and treating it with a reducing gas and steam. The objective of this project is to optimize the SNAP with respect to the performance of the adsorption and regeneration processes.
