Kupezeka kwa madzi kudzawonjezera kwambiri mame a mpweya wachilengedwe, kupangitsa kuti mpweya ukhale wosasunthika mu liquefaction, kunyamula mapaipi kapena kulekanitsa kuzizira kwambiri; kupanganso hydrocarbon hydrate kuti ipitirire ndikutseka zida ndi mapaipi; ndikosavuta kuchita ndi H2S ndi CO2 mu mpweya wachilengedwe ndikuwononga kwambiri zida za mapaipi. Kutaya madzi m'thupi kwambiri ndi kuumitsa mpweya wachilengedwe pogwiritsa ntchito molecular seeve ndiyo njira yogwiritsidwa ntchito kwambiri komanso yokhwima.
H2S ndi CO2 mu mpweya wachilengedwe zimagwira ntchito ndi madzi ndipo zimawononga kwambiri zida zapaipi; mpweya wachilengedwe wokhala ndi asidi wopitilira miyezo ya dziko lonse uyenera kugwiritsidwa ntchito nthawi zonse poyeretsa ndi kuchotsa sulfure. Sefa ya molekyulu yagwiritsidwa ntchito kwambiri pochotsa zinyalala monga H2S, CO2 mu mpweya.
