Igesi yemvelo itholakala ezingqimbeni ezingaphansi komhlaba ezinezimbobo, okuhlanganisa igesi yensimu kawoyela, igesi yensimu kagesi, igesi efakwe amalahle, igesi yentaba-mlilo edakeni kanye negesi ye-biogenic, kanti inani elincane layo livela emithungweni yamalahle. Iwuhlobo oluphezulu lwezinto zokusetshenziswa zikaphethiloli kanye namakhemikhali.
Igesi yemvelo isetshenziswa kakhulu njengophethiloli ukukhiqiza i-carbon black, amakhemikhali kanye negesi kaphethiloli encibilikisiwe. I-propane kanye ne-butane ezikhiqizwa yigesi yemvelo ziyizinto ezibalulekile embonini yanamuhla. Igesi yemvelo yakhiwa kakhulu yigesi ene-hydrocarbon ephansi yamamolekyuli kanye negesi engeyona i-hydrocarbon.
Igesi Yemvelo Ecindezelwe (i-CNG) yigesi yemvelo ecindezelwe (ngaphezu kuka-3,600 psi) futhi igcinwe esimweni segesi esitsheni. Inokwakheka okufanayo negesi yemvelo yepayipi.
Igesi yemvelo encibilikisiwe (i-LNG) igesi yemvelo ecindezelwe futhi igcinwe esimweni soketshezi esitsheni, esingasetshenziswa ukwenza i-CNG ngaphansi kwengcindezi encishisiwe. Uma kuqhathaniswa nendlela yendabuko yokukhiqiza i-CNG, izindleko zemishini yokunemba edingekayo kule nqubo ziphansi.
Igesi likaphethiloli elincibilikisiwe lingenye yemikhiqizo kaphethiloli (igesi likaphethiloli elincibilikisiwe, i-LPG), okuyigesi elingenambala neliguquguqukayo elitholakala ngokucindezela, ukupholisa, kanye nokukhipha uketshezi kugesi wokuhlanza noma igesi yemvelo (kufaka phakathi igesi ehlobene nensimu kaphethiloli). Izingxenye eziyinhloko zegesi likaphethiloli elincibilikisiwe elitholakala kugesi wokuhlanza yi-propane, i-propylene, i-butane, i-butene, kanye nenani elincane lokungcola kwe-pentane, i-pentene kanye ne-trace sulfur. Ukwakheka kwegesi elincibilikisiwe elitholakala kugesi yemvelo akunawo ama-olefin.
Uketshezi lwe-condensate lwegesi yemvelo (NGL) luyingxube ye-hydrocarbon elula ene-ethane, i-propane ne-butane njengezingxenye eziyinhloko ezitholakala ekuhlukanisweni kwegesi yemvelo okubangelwa yi-cryogenic.
Uwoyela we-condensate (i-COND) ubhekisela endaweni yokugcina igesi esesimweni esibucayi kakhulu ngaphansi kokucindezeleka okuphezulu kanye nezimo zokushisa okuphezulu ekwakhekeni. Uma imbiwa phansi, ingcindezi kanye nokushisa kuyancishiswa, bese umkhiqizo owuketshezi uhlanganiswa yi-retrograde condensation. Igesi engavundisiwe ibizwa ngokuthi i-condensate gas well gas gas. Ngezinye izikhathi igesi ehlotshaniswa nensimu kawoyela kanye negesi yemvelo emanzi, i-condensate etholakala ngenxa yokwehla kwezinga lokushisa, ibizwa nangokuthi uwoyela we-condensate, noma uphethiloli wemvelo.
