Abstract

Przedmiotem zgłoszenia jest sposób redukcji wysokich stężeń tlenków azotu w gazach odlotowych z wysokoprężnych silników Diesla, który charakteryzuje się tym, że do redukcji tych stężeń stosuje się najpierw technologię napromieniowania gazów odlotowych wiązką elektronów z akceleratora dawką napromieniowania, rzędu 10 - 12 kGy, gazów odlotowych o temperaturze nieprzekraczającej 90°C, a następnie metodę mokrego skrubera z odpowiednio przygotowaną wodą procesową, wzbogaconą roztworem silnego utleniacza/absorbentu NaClO2.
