Kukhalapo kwa madzi kudzakulitsa kwambiri mame a gasi, kupanga mpweya wosapeŵeka wotsekemera mu liquefaction, mayendedwe a mapaipi kapena kulekanitsa kozizira kwambiri;imapanganso hydrocarbon hydrate kuti igwetse ndikutsekereza zida ndi mapaipi;ndikosavuta kuchitapo kanthu ndi H2S ndi CO2 mu gasi wachilengedwe ndikuwononga kwambiri zida zamapaipi.Kutaya madzi m'thupi ndi kuyanika kwa gasi wachilengedwe ndi sieve ya molekyulu ndiyo njira yogwiritsidwa ntchito kwambiri komanso yokhwima.
H2S ndi CO2 mu gasi adzachita ndi madzi ndikuwononga kwambiri zida zamapaipi;Mafuta achilengedwe a asidi omwe ali ndi zinthu zopitilira muyeso wadziko ayenera kugwiritsidwa ntchito moyenera kudzera mu kuyeretsedwa ndi kuwononga sulfure.Sieve ya molekyulu yakhala ikugwiritsidwa ntchito kwambiri pochotsa zonyansa monga H2S, CO2 mu gasi.
