Igesi igama elivamile lamafutha egesi ashisa futhi akhiphe ukushisa ukuze asetshenziswe izakhamuzi zasemadolobheni namabhizinisi ezimboni. Kunezinhlobo eziningi zegesi, ikakhulukazi igesi yemvelo, igesi yokwenziwa, i-liquefied petroleum gas kanye ne-biogas.

Kunezinhlobo ezi-4 zegesi evamile yedolobha: Igesi Yemvelo, Igesi Yokwenziwa, Igesi Eliyi-Liquefied Petroleum, I-Substitute Natural Gas.

1. I-Liquefied Petroleum Gas:

I-LPG ikhiqizwa ikakhulukazi ezindaweni zokuhlanza amafutha ngesikhathi sokuqhekeka kokukhishwa kwamafutha, izingxenye zayo eziyinhloko ziyi-propane ne-butane, ezinamanani amancane we-propylene ne-butene.

2. Faka esikhundleni Igesi Yemvelo:

I-LPG iyashisisa futhi iguquguquke ibe yisimo segesi emishinini ekhethekile, futhi ngesikhathi esifanayo umthamo womoya (cishe u-50%) uxutshwa ukuze wandise umthamo wawo, unciphise ukugxila kwawo futhi unciphise inani lawo le-calorific ukuze linikezwe njenge igesi yemvelo.

3. Igesi Yokwenziwa:

Amagesi enziwe ngezinto zokubasa eziqinile ezifana namalahle ne-coke noma izibaso eziwuketshezi ezifana nowoyela osindayo ngokusebenzisa izinqubo ezifana ne-distillation eyomile, ukuhwamuka noma ukuqhekeka, okuyingxenye yayo eyinhloko i-hydrogen, i-nitrogen, i-carbon monoxide ne-carbon dioxide.

4. Igesi Yemvelo:

Igesi yemvelo evuthayo ekhona ngaphansi komhlaba ibizwa ngokuthi igesi yemvelo futhi ikakhulukazi yakhiwe i-methane, kodwa futhi iqukethe amanani amancane e-ethane, i-butane, i-pentane, i-carbon dioxide, i-carbon monoxide, i-hydrogen sulfide, njll.

Kunezinhlobo ezinhlanu zegesi yemvelo, kuye ngokuthi yakhiwe futhi yakhishwa kanjani:

1. Igesi yemvelo ehlanzekile: Igesi yemvelo ikhishwa ezindaweni ezingaphansi komhlaba.

2. Igesi ehlobene nowoyela: Lolu hlobo lwegesi lukhishwa ocezwini lwamafutha lubizwa ngokuthi igesi ehambisana nowoyela.

3. Igesi yasemayini: Igesi yasezimayini iqoqwa ngesikhathi sokumbiwa kwamalahle.

4. I-Condensate field gas: Igesi equkethe izingxenyana zokukhanya ze-petroleum.

5. Igesi ye-coalbed methane Mine: Ikhishwa emithungweni yamalahle engaphansi komhlaba

Lapho uletha igesi,ama-valve ebhola ephayiphi legesizisetshenziselwa ukulawula iziteshi zegesi zesango, ngenkathiamavalvu emitha yegesizisetshenziselwa ukulawula igesi yasendlini.
