Izindaba

I-nitrogen eyigesi engasebenzi esetshenziselwa ukusetshenziswa okuhlukahlukene endaweni yokumba uwoyela, izigaba zokusebenza kanye nokuqedwa kwemithombo kawoyela negesi, kanye nokugenca nokuhlanza amapayipi.

I-nitrogen isetshenziswa kakhulu kokubili ezicelweni zasolwandle okuhlanganisa:

ukuvuselela kahle,

umjovo kanye nokuhlolwa kwengcindezi

Ukutholwa Kawoyela Okuthuthukisiwe (EOR)

ukugcinwa kwe-reservoir pressure

ukufakwa kwe-nitrogen

ukuvimbela umlilo

Isetshenziselwa ukusekela imisebenzi yokumba, i-nitrogen isetshenziselwa ukufaka iphaneli yezinsimbi, kanye nokufaka igesi evuthayo, kanye nezinhlelo zokucindezela ukuhlanza nokuhlola.Ishintsha umoya owomile, i-nitrogen ingandisa ukuphila kwezinye izinhlelo, futhi ivimbele ukuwohloka.

Emsebenzini wokusebenza nokuqeda, i-nitrogen enengcindezi ephezulu (esebenzisa ama-compressor ane-high-pressure booster compressors) iyisinqumo esifanelekile sokususa uketshezi lomthombo ukuze kuqalwe ukugeleza nokuhlanza imithombo ngenxa yokuminyana kwayo okuphansi nezici zokucindezela okuphezulu.I-nitrogen enengcindezi ephezulu iphinde isetshenziselwe ukugqugquzela ukukhiqiza ngokusebenzisa i-hydraulic fracturing.

Ezigciniwe zikawoyela, i-nitrogen isetshenziselwa ukugcina ingcindezi lapho umfutho we-reservoir wehlile ngenxa yokuncipha kwama-hydrocarbons noma ngenxa yokuncipha kwengcindezi yemvelo.Ngenxa yokuthi i-nitrogen ayihambisani namafutha namanzi, uhlelo lomjovo we-nitrogen noma isikhukhula se-nitrogen sivame ukusetshenziselwa ukuhambisa amaphakethe ama-hydrocarbon aphuthelwe ukusuka emthonjeni womjovo kuya emthonjeni wokukhiqiza.

I-nitrogen itholwe iyigesi efanelekile yokugenca kanye nokuhlanza ipayipi.Isibonelo, i-nitrogen isetshenziswa njengamandla okushayela ukusunduza izingulube ngepayipi, ngokuphambene nomoya ocindezelwe owawusetshenziswa ngokwesiko.Izinkinga ezihambisana nomoya ocindezelweyo njengokugqwala nokuvutha, ziyagwenywa lapho i-nitrogen isetshenziselwa ukushayela ingulube epayipini.I-nitrogen ingabuye isetshenziselwe ukuhlanza ipayipi ngemva kokuqedwa kokufakwa kwezingulube.Kulesi simo, igesi ye-nitrogen eyomile iqhutshwa emgqeni ngaphandle kokuba ingulube yomise noma imaphi amanzi asele epayipini.

Esinye isicelo esikhulu sasolwandle se-nitrogen sikuma-FPSO nezinye izimo lapho kugcinwa khona ama-hydrocarbon.Enqubweni ebizwa ngokuthi i-tank blanketing, i-nitrogen isetshenziswa endaweni yokugcina engenalutho, ukwandisa ukuphepha kanye nokuhlinzeka ngesivimbeli sama-hydrocarbons angenayo.

Ngabe I-Nitrogen Generation isebenza kanjani?

Ubuchwepheshe be-PSA buhlinzeka ngokukhiqiza endaweni ngokusebenzisa okukhiphayo okuhlukahlukene kanye namajeneretha wamandla.Ukufinyelela kumazinga wokuhlanzeka afinyelela ku-99.9%, ukukhiqizwa kwe-nitrogen kwenze inqwaba yokusetshenziswa emkhakheni kawoyela negesi ukonga kakhulu.

Futhi, Ama-Membranes akhiqizwa yi-Air Liquide - I-MEDAL asetshenziselwa izicelo zokugeleza okuphezulu kwe-nitrogen.I-nitrogen ikhiqizwa ngokusebenzisa izihlungi ze-membrane ezinelungelo lobunikazi.

Inqubo yokukhiqiza i-PSA kanye neMembrane Nitrogen iqala ngokuthi umoya wasemkhathini uthathwe ufakwe ku-screw compressor.Umoya ucindezelwa kumfutho omisiwe nokugeleza komoya.

Umoya ocindezelwe uphakelwa ulwelwesi lokukhiqiza initrogen noma imojula ye-PSA.Ezingxenyeni ze-nitrogen, umoya-mpilo uyasuswa emoyeni, okuholela ku-nitrogen ezingeni lokuhlanzeka lika-90 kuya ku-99%.Endabeni ye-PSA, i-generator ingafinyelela amazinga okuhlanzeka afinyelele ku-99.9999%.Kuzo zombili izimo, i-nitrogen ehanjiswayo isezingeni eliphansi kakhulu lamazolo, okwenza kube igesi eyomile kakhulu.I-Dewpoint ephansi njenge-(-) 70degC ifinyeleleka kalula.

Kungani Kwenziwa I-Nitrogen Esizeni?

Ukunikeza ukonga okukhulu uma kuqhathaniswa, ukukhiqizwa kwe-nitrogen esizeni kuthanda kakhulu kunokuthunyelwa ngobuningi be-nitrogen.

Ukukhiqizwa kwe-nitrogen esizeni nakho kuyahambisana nemvelo njengoba ukukhishwa kwamaloli kugwenywa lapho ukulethwa kwe-nitrogen kwakwenziwa ngaphambili.

AmaGeneretha eNitrojeni ahlinzeka ngomthombo we-nitrogen oqhubekayo nothembekile, oqinisekisa ukuthi inqubo yekhasimende ayilokothi ime ngenxa yokuswela i-nitrogen.

Imbuyiselo yejeneretha ye-nitrogen ekutshalweni kwezimali (i-ROI) incane njengonyaka ongu-1 futhi ikwenza kube utshalomali olunenzuzo kunoma yiliphi ikhasimende.

Amajeneretha e-nitrogen anesilinganiso sempilo yeminyaka eyi-10 ngokulungiswa okufanele.
