Kwiyunithi yokunyibilikisa igesi yendalo, kukho iindlela ezintathu eziqhelekileyo zokucoca, ezizezi: indlela ye-alcohol amine, indlela ye-hot potash (eyenziwe nge-benfied) kunye indlela ye-sulfonol amine.
I-Mercury: ubukho be-mercury bunokugqwala kakhulu izixhobo ze-aluminium. Xa i-Mercury (kuquka i-elemental mercury, i-ion ze-mercury kunye nee-organic mercury compounds), i-aluminium iya kusabela namanzi ukuvelisa iimveliso zomhlwa ezimhlophe ezicoliweyo, eziya konakalisa kakhulu iipropati ze-aluminium. Inani elincinci kakhulu lomxholo we-mercury lanele ukubangela umonakalo omkhulu kwizixhobo ze-aluminium, kwaye i-Mercury nayo iya kubangela ungcoliseko lokusingqongileyo kunye nomonakalo kubasebenzi ngexesha lokugcinwa. Ke ngoko, umxholo we-mercury kufuneka ulinganiselwe ngokungqongqo. Susa i-mercury Lo mgaqo usekelwe kwimpendulo ye-mercury kunye ne-sulfur kwi-catalytic reactor.
I-hydrocarbon enzima: ibhekisa kwii-hydrocarbon ezingaphezulu kwe-C5+. Kwii-hydrocarbon, xa ubunzima beemolekyuli butshintsha ukusuka kwincinci ukuya kwinkulu, inqanaba layo lokubila liyatshintsha ukusuka kwisezantsi ukuya kwiphezulu. Ke ngoko, kumjikelo wokuxinana kwegesi yendalo, ii-hydrocarbon ezinzima zihlala zixinana kuqala. Ukuba i-hydrocarbon enzima ayihlukaniswanga kuqala, okanye yahlulwe emva kokuxinana, i-hydrocarbon enzima inokukhenkceza ize ivale izixhobo. Ii-hydrocarbon ezinzima zisuswa kancinci ngesihluzo se-molecular kunye nezinye izinto ezifaka amanzi emzimbeni ngexesha lokuphelelwa ngamanzi emzimbeni, kwaye ezinye zahlulwe ngokuhlukaniswa kwe-cryogenic.
I-Cos: inokumanziswa ngamanzi amancinci kakhulu ukuze yenze i-H2S kunye ne-CO2, nto leyo ebangela ukubola kwezixhobo. Kulula ukuyixuba ne-propane efunyenweyo. Idla ngokususwa kunye ne-H2S kunye ne-CO2 ngexesha lokunciphisa i-asidi.
I-Helium: igesi yendalo yeyona nto iphambili ekuveliseni i-helium kwaye kufuneka yahlulwe kwaye isetyenziswe. Isetyenziswa kakhulu ngokudityaniswa kokwahlulwa kwe-membrane kunye nokwahlulwa kwe-cryogenic.
I-nitrogen: ukwanda komxholo wayo kuya kwenza kube nzima ngakumbi ukunyibilika kwegesi yendalo. Indlela yokugqibela ye-flash isetyenziswa ngokubanzi ekususeni ngokukhethekileyo kwi-LNG.
Inxalenye ephambili yegesi yendalo yi-methane (CH4), kwaye iqondo layo lokubila eliqhelekileyo yi-111k (-162 ℃).
Uxinano lwe-methane engamanzi kwindawo yokubila eqhelekileyo yi-426kg / m3, kwaye uxinano lwe-methane yegesi kwimeko eqhelekileyo yi-0.717kg / m3, kunye nomahluko omalunga namaxesha angama-600. Umahluko omkhulu kumthamo sesona sizathu siphambili sokugcina kunye nokuthuthwa kwegesi yendalo enyibilikisiweyo.
