Igesi yemvelo iqukethwe ezindaweni ezinezimbotshana ezingaphansi komhlaba, okuhlanganisa igesi yasensimini kawoyela, igesi yenkundla yegesi, igesi yamalahle, igesi yentaba-mlilo yodaka kanye negesi ye-biogenic, kanti inani elincane layo livela emithungweni yamalahle. Iwuphethiloli wekhwalithi ephezulu kanye nempahla eluhlaza yamakhemikhali.
Igesi yemvelo isetshenziswa kakhulu njengophethiloli ukukhiqiza i-carbon black, amakhemikhali kanye negesi ye-petroleum ewuketshezi. I-propane ne-butane ekhiqizwa igesi yemvelo yizinto ezibalulekile zokusetshenziswa kwemboni yesimanje. Igesi yemvelo ikakhulukazi yakhiwa igesi ephansi ye-molecule ye-hydrocarbon kanye negesi engeyona i-hydrocarbon.
Igesi Yemvelo Ecindezelwe (CNG) igesi yemvelo ecindezelwa (ngaphezu kuka-3,600 psi) futhi igcinwe endaweni enegesi esitsheni. Inokwakheka okufanayo negesi yemvelo yamapayipi.
I-Liquefied natural gas (LNG) igesi yemvelo ecindezelwa futhi igcinwe esimweni esiwuketshezi esitsheni, esingasetshenziswa ukwenza i-CNG ngaphansi kwengcindezi encishisiwe. Uma kuqhathaniswa nendlela evamile yokukhiqiza i-CNG, izindleko zemishini enembayo edingwa yile nqubo ziphansi.
I-liquefied petroleum gas ingenye yemikhiqizo ye-petroleum (i-liquefied petroleum gas, i-LPG), okuyigesi engenambala futhi eguquguqukayo etholwe ngokucindezela, ukupholisa, nokuncibilikisa igesi yokuhluza noma igesi yemvelo (kuhlanganise negesi ehlobene nendawo kawoyela). Izingxenye eziyinhloko zegesi ye-petroleum ewuketshezi etholakala kugesi yokuhlanza i-propane, i-propylene, i-butane, i-butene, kanye nenani elincane le-pentane, i-pentene kanye ne-trace sulfur compound ukungcola. Ukwakheka kwegesi ewuketshezi etholakala kugesi yemvelo ngokuyisisekelo ayinawo ama-olefin.
I-Natural gas condensate liquid (NGL) iyingxube ye-hydrocarbon elula ene-ethane, i-propane ne-butane njengezingxenye eziyinhloko ezitholakala ekuhlukaniseni i-cryogenic yegesi yemvelo.
Amafutha e-Condensate (COND) abhekisela endaweni yokugcina igesi esesimweni esibucayi kakhulu ngaphansi kwengcindezi ephezulu kanye nezimo zokushisa eziphakeme ekubunjweni. Uma kumbiwa phansi, ukucindezela kanye nezinga lokushisa kuyancishiswa, futhi umkhiqizo we-liquid ofinyezwa yi-retrograde condensation kwenzeka. Igesi engancishiwe ibizwa nge-condensate gas source gas. Kwesinye isikhathi insimu kawoyela ehambisana negesi kanye negesi yemvelo emanzi, i-condensate etholwe ngenxa yokuncipha kwezinga lokushisa, ibizwa nangokuthi uwoyela we-condensate, noma uphethiloli wemvelo.
