Abstract

Menetelmä ainakin ensimmäisen pakokaasun (EG1) ja toisen pakokaasun (EG2) puhdistamiseksi. Menetelmässä pestään ensimmäinen ja toinen pakokaasu (EG1, EG2) ensimmäisessä ja toisessa pesurissa (710, 720) pestyn ensimmäisen ja toisen pakokaasun (SEG1, SEG2) saamiseksi, ja johdetaan ainakin osa pestystä ensimmäisestä ja toisesta pakokaasusta (SEG1, SEG2) sähkösuodattimeen (100). Menetelmässä lisäksi puhdistetaan joko mainittu ainakin osa pestystä ensimmäisestä pakokaasusta (SEG1) ja mainittu ainakin osa pestystä toisesta pakokaasusta (SEG2), tai molemmat, sähkösuodattimessa (100) puhtaan pakokaasun (CEG) saamiseksi. Järjestelmä menetelmän toteuttamista varten.
