Abstract

A method of removing ammonia from a gas stream may involve the steps of: Providing a primary slurry composition of a molybdic acid at a first pH; providing a secondary slurry composition of a molybdic acid at a second pH, the second pH being numerically lower than the first pH; atomizing the primary slurry composition in the presence of the gas stream to produce a partially processed gas stream, quantities of ammonia in the gas stream combining with the molybdic acid in the primary slurry composition to form a further concentrated primary ammoniated slurry composition; and atomizing the secondary slurry composition in the presence of the partially processed gas stream to produce a processed gas stream, additional quantities of ammonia in the partially processed gas stream combining with the molybdic acid in the secondary slurry composition to form a further concentrated secondary ammoniated slurry composition.
