Zokhudza kuyeretsedwa kwa chitoliro chopanda mafuta chopanda pake:
Mapaipi osungira mafuta opanda kanthu amatsukidwa ndikufika pamalo opangira mafuta.Asanayambe kukonza, banga lamafuta, nthaka ya laimu, dzimbiri la oxide sikelo ndi zokutira zakale zamkati ndi kunja kwa payipi ziyenera kutsukidwa.Njira zochotsera dzimbiri zimaphatikizapo manja, makina, kupopera, pickling, etc. M'mbuyomu, njira yopopera mankhwala inkagwiritsidwa ntchito makamaka pochotsa dzimbiri la mapaipi a oxygen.Tsopano, pickling imagwiritsidwa ntchito kuchotsa dzimbiri, ndipo zotsatira zake ndi zabwino kwambiri.Mukamatsuka ndi mpweya woponderezedwa kapena madzi, kuthamanga kwa madzi kapena kuthamanga kwa mpweya kumatha kufika 15x20m / s, zomwe zingathe kuchotsa dothi pamtunda wa chitoliro, koma simungathe kuchotsa dzimbiri, oxide scale, burr, chotupa chowotcherera ndi chotupa choponyera.
