Abstract

A low-concentration nitrogen oxide recovery unit with a capacity of 50 m³/h equipped with γ-Al₂O₃ granules saturated with a water solution of carbamide and ammonium bicarbonate has been developed, produced, and tested. During the tests, the unit operated for approximately 176 h; it maintained capture efficiency at a level of 90 to 95% for 156 h. The unit captured 3.6 kg of nitrogen dioxide during its operation period.
