Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 47 n°11 (Juin 2008) . - p. 3827–3833 Titre : Nitrogen oxides absorption on calcium hydroxide at low temperature Type de document : texte imprimé Auteurs : Xiaowen Zhang, Auteur ; Huiling Tong, Auteur ; Hu Zhang, Auteur ; Changhe Chen, Auteur Année de publication : 2008 Article en page(s) : p. 3827–3833 Note générale : Bibliogr. p. 3833 Langues : Anglais (eng) Mots-clés : Calcium hydroxide  Nitrogen oxides  Water vapor  Absorption process Résumé : Solid Ca(OH)2 was used to absorb NO and NO2 with water vapor present in the flue gas. Nitrogen oxides were captured as nitrite and nitrate, and part of NO could be released into the gas as the HNO2 decomposed, which was produced in the absorption process. A mathematical model was founded to predict the process of NOx absorption and nitrite and nitrate production. With the overall kinetic parameters (OKPs) evaluated by the typical experimental result at 70 °C and 60% relative humidity, the model can simulate the experimental results at various conditions quantitatively.
