Izibani Zokufakazela Ukuqhuma Zihlukaniswe Ngamaleveli amaningana

Ukukhanyisa okuvikela ukuqhuma kuhlukaniswe ngezigaba ezintathu: IIA, IIB, kanye ne-IIC.

Ikilasi IIA

Ifanele izindawo ezinezinto ezifana nophethiloli, njengamagalaji kaphethiloli. Igesi emele lesi sigaba i-propane.

Ikilasi IIB

Kusetshenziswa ezimbonini ezijwayelekile lapho kukhona amagesi ayingozi. I-Ethylene igesi emele lokhu kuhlukaniswa.
