Igesi yendalo ifumaneka kwiindawo ezingaphantsi komhlaba ezinemingxuma, kuquka igesi yentsimi yeoyile, igesi yentsimi yegesi, igesi ebekwe kumalahle, igesi yentaba-mlilo yodaka kunye negesi yebhayoloji, kwaye inani elincinci layo livela kwiintlama zamalahle. Yimpahla eluhlaza ekumgangatho ophezulu yamafutha kunye neekhemikhali.
Igesi yendalo isetyenziswa kakhulu njengepetroli ukuvelisa i-carbon black, iikhemikhali kunye negesi yepetroleum enyibilikisiweyo. Ipropane kunye ne-butane eziveliswa yigesi yendalo zizinto ezibalulekileyo kwimizi-mveliso yanamhlanje. Igesi yendalo ikakhulu yenziwe yigesi ene-hydrocarbon ephantsi yeemolekyuli kunye negesi engeyiyo i-hydrocarbon.
Igesi yendalo ecinezelweyo (i-CNG) yigesi yendalo exinezelekileyo (ngaphezulu kwe-3,600 psi) kwaye igcinwe kwimeko yegesi kwisikhongozeli. Inokwakheka okufanayo negesi yendalo yepayipi.
Igesi yendalo enyibilikisiweyo (i-LNG) igesi yendalo exinezelekileyo kwaye igcinwa kwimeko yolwelo kwisikhongozeli, esinokusetyenziselwa ukwenza i-CNG phantsi koxinzelelo oluphantsi. Xa kuthelekiswa nendlela yendabuko yokuvelisa i-CNG, ixabiso lezixhobo ezichanekileyo ezifunekayo kule nkqubo liphantsi.
Igesi yepetroleum enyibilikisiweyo yenye yeemveliso zepetroleum (igesi yepetroleum enyibilikisiweyo, i-LPG), eyigesi engenambala neguquguqukayo efunyanwa ngokucinezela, ukupholisa, kunye nokunyibilikisa igesi yokucoca okanye igesi yendalo (kubandakanya igesi enxulumene ne-oyile). Izinto eziphambili zegesi yepetroleum enyibilikisiweyo efunyenwe kwigesi yokucoca yipropane, ipropylene, i-butane, i-butene, kunye nobuninzi obuncinci be-pentane, i-pentene kunye ne-trace sulfur compound impurities. Ukwakheka kwegesi enyibilikisiweyo efunyenwe kwigesi yendalo ngokusisiseko ayinazo ii-olefins.
Ulwelo lwe-condensate lwegesi yendalo (NGL) ngumxube we-hydrocarbon olula kunye ne-ethane, i-propane kunye ne-butane njengezinto eziphambili ezifunyenwe kulwahlulo lwegesi yendalo oluvela kwi-cryogenic.
Ioyile ye-condensate (i-COND) ibhekisa kwindawo yokugcina igesi ekwimeko enzima kakhulu phantsi koxinzelelo oluphezulu kunye neemeko zobushushu obuphezulu xa isenziwa. Xa imbiwa emhlabeni, uxinzelelo kunye nobushushu buyancitshiswa, kwaye imveliso yolwelo edityaniswe yi-retrograde condensation iyenzeka. Igesi engadityanisiweyo ibizwa ngokuba yi-condensate gas well gas gas. Ngamanye amaxesha igesi enxulumene ne-oyile kunye negesi yendalo emanzi, i-condensate efunyenwe ngenxa yokwehla kobushushu, ikwabizwa ngokuba yi-condensate oil, okanye ipetroli yendalo.
