Nayitrojeni kukhala gasi wa inert wogwiritsidwa ntchito mosiyanasiyana pobowola mafuta, kugwirira ntchito ndikumaliza kwa zitsime zamafuta ndi gasi, komanso kukumba ndi kuyeretsa mapaipi.

Nayitrogeni imagwiritsidwa ntchito kwambiri pamagwiritsidwe am'mphepete mwa nyanja kuphatikiza:

kulimbikitsa bwino,

jekeseni ndi kuyezetsa kuthamanga

Kubwezeretsanso Mafuta Owonjezera (EOR)

posungira kuthamanga kwa posungira

nitrogen nkhumba

kuteteza moto

Amagwiritsidwa ntchito kuthandizira pobowola, nayitrogeni imagwiritsidwa ntchito polowetsa zida zamagetsi, komanso kulowetsa mpweya wamoto, komanso makina othamangitsira ndikuyesa.M'malo mwa mpweya wouma, nayitrogeni imatha kukulitsa moyo wa machitidwe ena, komanso kupewa kuwonongeka.

Pogwira ntchito komanso pomaliza, nayitrogeni wothamanga kwambiri (pogwiritsa ntchito ma compressor amphamvu kwambiri) ndi njira yabwino yosinthira madzi amchere kuti ayambitse kutuluka ndi kuyeretsa zitsime chifukwa cha kutsika kwake komanso kupanikizika kwambiri.Nayitrogeni wothamanga kwambiri amagwiritsidwanso ntchito polimbikitsa kupanga kudzera pa hydraulic fracturing.

M'malo osungiramo mafuta, nayitrogeni amagwiritsidwa ntchito posunga kupanikizika komwe kumachepetsa mphamvu ya nkhokwe chifukwa cha kuchepa kwa ma hydrocarboni kapena chifukwa chochepetsa mphamvu yachilengedwe.Chifukwa nayitrogeni sagwirizana ndi mafuta ndi madzi, jekeseni wa nayitrojeni kapena kusefukira kwa nayitrogeni amagwiritsidwa ntchito nthawi zambiri kusamutsa matumba osowekera a ma hydrocarbons kuchokera mu jakisoni kupita pachitsime chopangira.

Nayitrojeni wapezeka kuti ndi mpweya wabwino kwambiri pakuweta nkhumba ndi kutsuka mapaipi.Mwachitsanzo, nayitrogeni amagwiritsidwa ntchito ngati mphamvu yoyendetsa nkhumba kupyola mutoliro, kusiyana ndi mpweya woponderezedwa umene unkagwiritsidwa ntchito kale.Mavuto okhudzana ndi mpweya woponderezedwa monga dzimbiri ndi kuyaka, amapewedwa pamene nayitrogeni imagwiritsidwa ntchito kuyendetsa nkhumba kupyola payipi.Nayitrojeni itha kugwiritsidwanso ntchito kutsuka mapaipi akamaliza kuweta nkhumba.Pamenepa, mpweya wouma wa nayitrogeni umadutsa pamzere popanda nkhumba kuti iwumitse madzi otsala mupaipi.

Ntchito ina yayikulu yakunyanja ya nayitrogeni ili mu FPSO ndi nthawi zina pomwe ma hydrocarbon amasungidwa.Munjira yotchedwa tank blanketing, nayitrogeni amayikidwa pamalo osungira opanda kanthu, kuonjezera chitetezo ndikupereka chotchinga cha ma hydrocarbon olowa.

Kodi Nitrogen Generation Imagwira Ntchito Motani?

Ukadaulo wa PSA umapereka m'badwo wapamalo kudzera pazotulutsa zosiyanasiyana komanso majenereta amphamvu.Kufikira ku chiyero cha 99.9%, kupanga nayitrogeni kwapangitsa kuti ntchito zambirimbiri pazamafuta ndi gasi zikhale zandalama.

Komanso, Ma Membranes opangidwa ndi Air Liquide - MEDAL amagwiritsidwa ntchito popanga nitrogen yambiri.Nayitrogeni amapangidwa kudzera muzosefera za membrane zovomerezeka.

Kapangidwe ka PSA ndi Membrane Nayitrojeni imayamba ndi mpweya wa mumlengalenga kutengedwa mu screw compressor.Mpweya umapanikizidwa kuti ukhale ndi mphamvu yodziwika komanso kuyenda kwa mpweya.

Mpweya woponderezedwa umadyetsedwa ku membrane yopanga nayitrogeni kapena gawo la PSA.Mu nembanemba ya nayitrogeni, mpweya umachotsedwa mumlengalenga, zomwe zimapangitsa kuti nayitrogeni pamlingo wachiyero wa 90 mpaka 99%.Pankhani ya PSA, jenereta imatha kukwaniritsa milingo yoyera mpaka 99.9999%.Muzochitika zonsezi, nayitrogeni yoperekedwa ndi mame otsika kwambiri, zomwe zimapangitsa kukhala mpweya wouma kwambiri.Dewpoint yotsika ngati (-) 70degC imapezeka mosavuta.

Chifukwa Chiyani Kupanga Nayitrogeni Patsamba?

Popereka ndalama zambiri poyerekeza, kutulutsa kwa nayitrogeni pamalowa kumakondedwa kuposa kutumiza nayitrogeni wambiri.

Kupanga nayitrojeni pamalowo kulinso kogwirizana ndi chilengedwe chifukwa kutulutsa mpweya wamagalimoto kumapewedwa komwe kunkachitika kale.

Majenereta a Nayitrogeni amapereka gwero lopitilira komanso lodalirika la nayitrogeni, kuwonetsetsa kuti kasitomala sayima chifukwa chosowa nayitrogeni.

Kubwezeretsa kwa jenereta wa nayitrogeni pazachuma (ROI) kumakhala kochepera chaka chimodzi ndipo kumapangitsa kukhala ndalama zopindulitsa kwa kasitomala aliyense.

Majenereta a nayitrogeni amakhala ndi moyo wazaka 10 ndikusamalidwa bwino.
