Ammonia stripping and scrubbing for mineral nitrogen recovery

Boekbijdrage - Hoofdstuk

Biological ammonia (NH3) stripping and scrubbing results in the production of chemical building blocks suitable for the production of marketable biobased fertilizers or other chemical products. This chapter deals with NH3 stripping and scrubbing processes for recovery of mineral nitrogen. It discusses different configurations for the recovery of NH3 as air scrubber water from waste air and effluent streams, mainly focusing on livestock production and anaerobic digestion. The chapter provides a brief overview of a variety of chemicals (organic acids, nitric acid, and gypsum) that have been investigated as alternatives to H2SO4 in order to capture NH3 in scrubbing towers. It examines successful full-scale applications of NH3 recovery from different waste origins. The chapter also looks at the quality characteristics of the recovered ammonium sulfate or ammonium nitrate.
