Abstract

طريقة ونظام لإزالة أكاسيد النيتروجين nitrogen oxides من غاز المداخن من منشآت الاحتراق، تشتمل الطريقة على خطوات تمرير غاز المداخن عبر مرشح سيراميك واحد أو أكثر المحفزة بمحفز من أجل الاختزال الانتقائي لأكاسيد النيتروجين في وجود الأمونيا ammonia المضافة إلى غاز المداخن إما على هذا النحو أو في شكل سلائف منه؛ عند درجة حرارة أقل من 250 درجة مئوية يتم حقن غاز متدفق يحتوي على ثاني أكسيد النيتروجين في غاز المداخن في اتجاه أعلى مصب مرشح سيراميك واحد أو أكثر؛ توفير الغاز المتدفق الذي يحتوي على ثاني أكسيد النيتروجين nitrogen dioxide من خلال الخطوات التالية: أكسدة الأمونيا أو سلائفها تحفيزيًا مع أكسجين يحتوي على الهواء إلى غاز متدفق يحتوي على أول أكسيد النيتروجين nitrogen monoxide والأكسجين في وجود حفاز للأكسدة؛ تبريد الغاز المتدفق إلى درجة حرارة المحيط وأكسدة أول أكسيد النيتروجين في الغاز المتدفق المبرد إلى ثاني أكسيد النيتروجين المحتوي على غاز متدفق.
