Azote kuba gazi ya inert ikoreshwa mubikorwa bitandukanye mugucukura peteroli, gukora no kurangiza ibyiciro bya peteroli na gaze, ndetse no mu ngurube no gutunganya imiyoboro.
Azote ikoreshwa cyane haba murwego rwo hanze harimo:
kubyutsa neza,
gupima inshinge
Kongera Amavuta Yongeye Kugarura (EOR)
kubungabunga igitutu cyibigega
ingurube
gukumira umuriro
Azote ikoreshwa mugushigikira ibikorwa byo gucukura, azote ikoreshwa mugukoresha ibikoresho, hamwe na gaz ya flare, hamwe na sisitemu yo guhanagura no kugerageza.Gusimbuza umwuka wumye, azote irashobora kongera ubuzima bwa sisitemu zimwe, kimwe no kwirinda gusenyuka.
Mubikorwa byo kurangiza no kurangiza, azote yumuvuduko mwinshi (ukoresheje compressor yumuvuduko ukabije) ni amahitamo meza yo kwimura amazi meza kugirango utangire gutemba no gusiba amariba kubera ubwinshi bwayo nibiranga umuvuduko mwinshi.Azote yumuvuduko ukabije nayo ikoreshwa mugukangura umusaruro binyuze mumeneka ya hydraulic.
Mu bigega bya peteroli, azote ikoreshwa mu gukomeza umuvuduko aho umuvuduko w’ibigega wagabanutse bitewe no kugabanuka kwa hydrocarbone cyangwa bitewe n’igabanuka ry’umuvuduko kamere.Kubera ko azote idashobora gukoreshwa n'amavuta n'amazi, gahunda yo gutera azote cyangwa umwuzure wa azote ukoreshwa kenshi mu kwimura imifuka yabuze ya hydrocarbone kuva ku iriba ryatewe inshinge ikajya ku iriba ribyara umusaruro.
Azote yasanze ari gaze nziza yo kuvuza ingurube no gutunganya umuyoboro.Kurugero, azote ikoreshwa nkimbaraga zo gusunika ingurube zinyuze mu muyoboro, bitandukanye n’umwuka ucanye wasanzwe ukoreshwa.Ibibazo bifitanye isano numwuka uhumanye nka ruswa no gutwikwa, birindwa mugihe azote ikoreshwa mugutwara ingurube mumiyoboro.Azote irashobora kandi gukoreshwa mugusukura umuyoboro nyuma yingurube zirangiye.Muri iki gihe, gaze ya azote yumye ikoreshwa mumurongo idafite ingurube kugirango yumishe amazi asigaye mumuyoboro.
Ubundi buryo bukomeye bwo gukoresha porogaramu ya azote ni muri FPSOs nibindi bihe bibikwa hydrocarbone.Mubikorwa byitwa tank gupfunyika, azote ikoreshwa mububiko bwubusa, kugirango umutekano wiyongere kandi utange buffer kugirango hydrocarbone yinjira.
Nigute Igisekuru cya Azote gikora?
Ikoranabuhanga rya PSA ritanga ibisekuruza kurubuga binyuze mubisohoka bitandukanye kandi bitanga ingufu.Kugera ku kigero cya 99.9% byera, kubyara azote byatumye umubare munini wibikorwa bya peteroli na gaze byubukungu.
Nanone, Membrane yakozwe na Air Liquide - MEDAL ikoreshwa mugukoresha azote nyinshi.Azote ikorwa binyuze muri patenti ya membrane.
Gahunda yo gukora azote ya PSA na Membrane itangirana numwuka wo mu kirere ujyanwa muri compressor ya screw.Umwuka uhagarikwa kumuvuduko wabigenewe no gutembera kwumwuka.
Umwuka uhumanye ugaburirwa umusaruro wa azote cyangwa module ya PSA.Muri azote, ogisijeni ikurwa mu kirere, bikavamo azote ku rwego rwa 90 kugeza 99%.Ku bijyanye na PSA, generator irashobora kugera ku rwego rwo hejuru kugeza kuri 99,9999%.Muri ubwo buryo bwombi, azote yatanzwe ni ikime cyo hasi cyane, bigatuma gaze yumye cyane.Ikibanza kiri hasi nka (-) 70degC birashoboka kugerwaho.
Kuki Kurubuga rwa Azote?
Gutanga kuzigama kwinshi ugereranije, kubyara nitorojeni ikunzwe kuruta ibyoherejwe na azote.
Umusaruro wa azote ku mbuga nawo wangiza ibidukikije kuko birinda imyuka y’amakamyo aho gutanga azote byakorwaga mbere.
Amashanyarazi ya azote atanga isoko ihoraho kandi yizewe ya azote, ituma inzira yumukiriya itigera ihagarara kubera gushaka azote.
Amashanyarazi ya azote agaruka ku ishoramari (ROI) ni nkumwaka 1 kandi bituma ishoramari ryunguka kubakiriya bose.
Amashanyarazi ya azote afite impuzandengo yubuzima bwimyaka 10 hamwe no kuyitaho neza.
