Mpweya wachilengedwe umapezeka m'magawo apansi pa nthaka okhala ndi mabowo, kuphatikizapo mpweya wa m'munda wamafuta, mpweya wa m'munda wamafuta, mpweya wokhala ndi malasha, mpweya wa volcanic wopangidwa ndi matope ndi mpweya wa biogenic, ndipo pang'ono pake umachokera ku malasha. Ndi mafuta abwino kwambiri komanso zinthu zopangira mankhwala.
Mpweya wachilengedwe umagwiritsidwa ntchito makamaka ngati mafuta popanga mpweya wakuda wa kaboni, mankhwala ndi mpweya wa petroleum wosungunuka. Propane ndi butane zomwe zimapangidwa ndi mpweya wachilengedwe ndi zinthu zofunika kwambiri pamakampani amakono. Mpweya wachilengedwe umapangidwa makamaka ndi mpweya wa hydrocarbon wochepa komanso wopanda hydrocarbon.
Mpweya Wachilengedwe Wopanikizika (CNG) ndi mpweya wachilengedwe womwe umapanikizika (kupitirira 3,600 psi) ndikusungidwa mu mpweya mu chidebe. Uli ndi kapangidwe kofanana ndi mpweya wachilengedwe wapaipi.
Mpweya wachilengedwe wosungunuka (LNG) umayikidwa mu mpweya wachilengedwe wopanikizika ndipo umasungidwa mu chidebe, chomwe chingagwiritsidwe ntchito kupanga CNG pansi pa kupanikizika kochepa. Poyerekeza ndi njira yachikhalidwe yopangira CNG, mtengo wa zida zolondola zomwe zimafunika pa njirayi ndi wotsika.
Mpweya wa petroleum wosungunuka ndi umodzi mwa zinthu zopangidwa ndi mafuta (mpweya wa petroleum wosungunuka, LPG), womwe ndi mpweya wopanda mtundu komanso wosasunthika womwe umapezeka poika mphamvu, kuziziritsa, ndi kusungunula mpweya wosungunuka kapena mpweya wachilengedwe (kuphatikiza mpweya wogwirizana ndi mafuta). Zigawo zazikulu za mpweya wa petroleum wosungunuka womwe umapezeka kuchokera ku mpweya wosungunuka ndi propane, propylene, butane, butene, ndi zinthu zochepa zodetsedwa ndi pentane, pentene ndi sulfure. Kapangidwe ka mpweya wosungunuka womwe umapezeka kuchokera ku mpweya wachilengedwe kwenikweni ulibe ma olefins.
Madzi achilengedwe a condensate (NGL) ndi osakaniza pang'ono a hydrocarbon okhala ndi ethane, propane ndi butane monga zigawo zazikulu zomwe zimapezeka kuchokera ku cryogenic leating ya gasi wachilengedwe.
Mafuta a condensate (COND) amatanthauza malo osungiramo gasi omwe ali mu mkhalidwe wovuta kwambiri pansi pa kupanikizika kwakukulu ndi kutentha kwakukulu pakupangidwa. Akamakumba pansi, kuthamanga ndi kutentha kumachepa, ndipo chinthu chamadzimadzi chomwe chimasungunuka ndi kuzizira kwa retrograde chimachitika. Mpweya wosazizira umatchedwa mpweya wa condensate. Nthawi zina mpweya wogwirizana ndi mafuta ndi mpweya wachilengedwe wonyowa, womwe umapezeka chifukwa cha kuchepa kwa kutentha, umatchedwanso mafuta a condensate, kapena mafuta achilengedwe.
