Iindaba

I-nitrojeni yigesi engasebenziyo esetyenziselwa usetyenziso olwahlukeneyo kwindawo yokomba yeoli, ukusetyenzwa kunye nezigaba zokugqityezelwa kwemithombo yeoli nerhasi, kunye nokugrumba nokucoca imibhobho.

I-nitrogen isetyenziswa kakhulu kwizicelo zangaphandle konxweme kubandakanya:

ukuvuselela kakuhle,

Isitofu kunye novavanyo loxinzelelo

UkuBuyiswa kwakhona kweOyile (EOR)

ukugcinwa koxinzelelo logcino

ukufakwa kwenitrogen

ukuthintela umlilo

Isetyenziselwa ukuxhasa imisebenzi yokomba, initrogen isetyenziselwa ukungeniswa kwepaneli yesixhobo, kunye nokufaka igesi yomlilo, kunye neenkqubo zoxinzelelo kunye novavanyo.Ukutshintsha umoya owomileyo, initrogen inokwandisa ubomi bezinye iinkqubo, kunye nokuthintela ukophuka.

Ekusebenzeni nasekugqityweni kwemisebenzi, i-nitrogen ephezulu yoxinzelelo (usebenzisa i-high-pressure booster compressors) lukhetho olufanelekileyo lokususa ulwelo lwamanzi ukuze uqalise ukuhamba kunye nokucoca amaqula ngenxa yobuninzi obuphantsi kunye neempawu zoxinzelelo oluphezulu.Initrogen yoxinzelelo oluphezulu ikwasetyenziselwa ukuvuselela imveliso ngokuqhekeka kwehydraulic fracturing.

Kwiindawo zokugcina i-oyile, initrogen isetyenziselwa ukugcina uxinzelelo apho uxinezeleko lwereservoir luye lwehla ngenxa yokuncipha kweehydrocarbons okanye ngenxa yokuncipha koxinzelelo lwendalo.Ngenxa yokuba i-nitrogen ayihambelani ne-oyile namanzi, inkqubo yokutofa initrogen okanye isikhukula senitrogen sihlala sisetyenziswa ukuhambisa iipokotho eziphosiweyo zeehydrocarbons ukusuka kwinaliti ukuya kwiqula lemveliso.

I-nitrojeni ifunyenwe iyeyona rhasi ifanelekileyo yokukhwela iihagu kunye nokucoca imibhobho.Umzekelo, initrogen isetyenziswa njengamandla okuqhuba ukutyhala iihagu ngombhobho, ngokuchaseneyo nomoya ocinezelweyo owawusetyenziswa ngokwesintu.Iingxaki ezayanyaniswa nomoya ocinezelweyo ezifana nomhlwa kunye nokutsha, ziyanqandwa xa initrogen isetyenziselwa ukuqhuba ihagu kumbhobho.I-nitrogen ingasetyenziselwa ukucoca lo mbhobho emva kokuba kugqitywe ukugrunjwa kweehagu.Kule meko, igesi yenitrogen eyomileyo iqhutywa emgceni ngaphandle kokuba ihagu yomise nawaphina amanzi aseleyo kumbhobho.

Esinye isicelo esikhulu se-offshore se-nitrogen sikwii-FPSO kunye nezinye iimeko apho ii-hydrocarbons zigcinwa khona.Kwinkqubo ebizwa ngokuba yitanki yokugquma, initrogen ifakwa kwindawo yokugcina engenanto, ukwandisa ukhuseleko kunye nokubonelela ngesithinteli sokungena kweehydrocarbons.

Sisebenza njani isiZukulwana seNitrojeni?

Itekhnoloji ye-PSA ibonelela ngokuveliswa kwindawo ngemveliso eyahlukeneyo kunye neejenereyitha zamandla.Ukufikelela kuma-99.9% amanqanaba okucoceka, ukuveliswa kwenitrogen kwenze intaphane yezicelo kwintsimi yeoli negesi ukonga ngakumbi.

Kwakhona, iiMembranes eziveliswa yiAir Liquide – MEDAL zisetyenziselwa ukugeleza okuphezulu kwenitrogen.I-nitrogen iveliswa ngezihluzo ze-membrane ezine-patent.

I-PSA kunye neMembrane yenkqubo yokuvelisa iNitrogen iqala ngokuthathwa komoya womoya kwi-screw compressor.Umoya uxinzelelwe kuxinzelelo olumiselweyo kunye nokuhamba komoya.

Umoya ocinezelweyo utyiswa kwi-membrane yokuvelisa initrogen okanye imodyuli yePSA.Kwimibhobho ye-nitrogen, i-oksijini iyasuswa emoyeni, ibangele i-nitrogen kwinqanaba lokucoceka kwe-90 ukuya kwi-99%.Kwimeko ye-PSA, i-generator inokufikelela kumanqanaba okucoceka phezulu njenge-99.9999%.Kuzo zombini ezi meko, ukuhanjiswa kwenitrogen yindawo yombethe ephantsi kakhulu, iyenza ibe yirhasi eyome kakhulu.I-Dewpoint isezantsi njenge (-) 70degC ifikeleleka ngokulula.

Kutheni kukho isiZukulwana seNitrojeni kwiNdawo?

Ukubonelela ngolondolozo olukhulu xa kuthelekiswa, ukuveliswa kwenitrogen kwisiza kuyakhethwa ngaphezu kokuthunyelwa kwenitrogen eninzi.

Imveliso ye-nitrogen kwisiza nayo ihambelana nokusingqongileyo njengoko ukukhutshwa kweelori kuthintelwa apho ukuhanjiswa kwenitrogen bekusenziwa ngaphambili.

IiJenereyitha zeNitrojeni zibonelela ngomthombo oqhubekayo nothembekileyo wenitrogen, eqinisekisa ukuba inkqubo yomthengi ayize ime ngxi ngenxa yokuswela initrogen.

Imbuyekezo ye-Nitrogen generator kutyalo-mali (i-ROI) incinci njenge-1-year kwaye iyenza ibe lutyalo-mali olunengeniso kuye nawuphi na umthengi.

Iijenereyitha ze-nitrojeni zinobomi obuqhelekileyo beminyaka eyi-10 kunye nokugcinwa okufanelekileyo.
