Gasi ndi mawu omwe amatanthawuza mafuta omwe amawotcha ndi kutulutsa kutentha kuti agwiritsidwe ntchito ndi anthu okhala m'matauni ndi mabizinesi akumafakitale. Pali mitundu yambiri ya gasi, makamaka gasi wachilengedwe, gasi wochita kupanga, gasi wamafuta opangidwa ndi liquefied ndi biogas.

Pali mitundu inayi ya gasi wamba wa mtawuni: Gasi Wachilengedwe, Gasi Wopanga, Gasi Wosungunuka, Gasi Wachilengedwe.

1. Gasi Wosungunuka wa Petroleum:

LPG imapangidwa makamaka kuchokera ku mafuta opangira mafuta panthawi ya kusweka kwa mafuta, zigawo zake zazikulu ndi propane ndi butane, zomwe zimakhala ndi propylene ndi butene.

2. Gasi Wachilengedwe Wolowa M'malo:

LPG imatenthedwa ndikusinthidwa kukhala mpweya wokhala ndi zida zapadera, ndipo panthawi imodzimodziyo mpweya wochuluka (pafupifupi 50%) umasakanikirana kuti uwonjezere voliyumu yake, kuchepetsa ndende yake ndi kuchepetsa mtengo wake wa calorific kuti athe kuperekedwa monga gasi wachilengedwe.

3. Gasi Wopanga:

Mpweya wopangidwa kuchokera kumafuta olimba monga malasha ndi coke kapena mafuta amadzimadzi monga mafuta olemera kudzera munjira monga distillation youma, vaporization kapena kusweka, zomwe zigawo zake zazikulu ndi hydrogen, nayitrogeni, carbon monoxide ndi carbon dioxide.

4. Gasi Wachilengedwe:

Mpweya woyaka moto womwe umapezeka pansi pa nthaka umatchedwa gasi wachilengedwe ndipo umapangidwa makamaka ndi methane, komanso uli ndi ethane, butane, pentane, carbon dioxide, carbon monoxide, hydrogen sulfide, etc.

Pali mitundu isanu ya gasi, kutengera momwe amapangidwira ndikuchotsedwa:

1. Gasi weniweni: Gasi wachilengedwe amatengedwa kuchokera pansi pa nthaka.

2. Gasi Wogwirizana ndi Mafuta: Gasi wamtunduwu amatengedwa kuchokera kumafuta amatchedwa gasi ogwirizana ndi mafuta.

3. Mpweya wamigodi: Gasi wamumigodi amasonkhanitsidwa panthawi yamigodi ya malasha.

4. Gasi wakumunda wa condensate: Gasi wokhala ndi tizigawo towala tamafuta.

5. Coalbed methane Mine gasi: Amatengedwa kuchokera pansi pa nthaka seams

Popereka gasi,ma valve a mpira wa gasiamagwiritsidwa ntchito poyang'anira malo opangira mafuta, pomwema valve a gasi mitaamagwiritsidwa ntchito kuwongolera gasi wapanyumba.
