Iyunithi yokubuyisela i-NGL

Inkcazo emfutshane:

Ukubuyiswa kwe-hydrocarbon ekhaphukhaphu kubhekisa kwinkqubo yokubuyiswa kolwelo lwezinto ezinzima kwigesi yendalo kune-methane okanye i-ethane. Kwelinye icala, ijolise ekulawuleni i-hydrocarbon dew point yegesi yendalo ukuze ifikelele kwi-index yomgangatho wegesi yorhwebo kwaye iphephe ukuhamba kwegesi-ulwelo okunezigaba ezimbini.

Inkcazo

Kwelinye icala, iihydrocarbon ezingamanzi ezifunyenweyo zinexabiso elikhulu kwezoqoqosho, ezingasetyenziswa ngqo njengepetroli okanye zahlulwe zibe ngumxube we-ethane, ipropane, i-butane okanye i-propylene butane (igesi enyibilikisiweyo), ioyile ekhaphukhaphu, njl.njl., kwaye zingasetyenziswa njengezinto ezikrwada zekhemikhali. Ukuba igesi iphinda itsalwe ukuze kugcinwe uxinzelelo lwe-reservoir kwaye kwandiswe ukubuyiswa kweoyile negesi, i-C2+ kufuneka isuswe kangangoko kunokwenzeka.

Isizathu sokubuyisela ulwelo lwegesi yendalo: Ukuphucula umgangatho wegesi yendalo, ukunciphisa i-hydrocarbon dew point kunye nokuthintela ukufuma kwe-hydrocarbon engamanzi ekuthuthweni kwemibhobho; Iimveliso ze-condensate ezifunyenweyo zibalulekile kumafutha oluntu kunye namafutha eekhemikhali; Izinga lokusetyenziswa kwezixhobo linikezelwa, elineenzuzo ezilungileyo kwezoqoqosho.
