Kuchepetsa nayitrogeni yamadzimadzi ya mafakitale nthawi zambiri kumatanthauza kupanga nayitrogeni yamadzimadzi muzipangizo kapena makina ang'onoang'ono. Kusinthasintha kumeneku kumapangitsa kupanga nayitrogeni yamadzimadzi kukhala kosavuta, kosavuta kunyamula komanso koyenera kugwiritsidwa ntchito m'njira zosiyanasiyana.

Pa kuchepetsa nayitrogeni yamadzimadzi yamakampani, pali njira zotsatirazi makamaka:

Mayunitsi osavuta okonzekera nayitrogeni yamadzimadzi: Mayunitsi awa nthawi zambiri amagwiritsa ntchito ukadaulo wolekanitsa mpweya kuti atulutse nayitrogeni mumlengalenga pogwiritsa ntchito njira monga kulowetsedwa kapena kulekanitsa nembanemba, kenako amagwiritsa ntchito makina oziziritsira kapena zokulitsa kuti aziziritse nayitrogeniyo kuti ikhale yamadzimadzi. Mayunitsi awa nthawi zambiri amakhala ochepa kuposa mayunitsi akuluakulu olekanitsa mpweya ndipo ndi oyenera kugwiritsidwa ntchito m'mafakitale ang'onoang'ono, ma laboratories kapena komwe kumafunika kupanga nayitrogeni pamalopo.

Kuchepetsa mpweya wochepa kutentha: Njira yochepetsera mpweya wochepa kutentha ndi njira yodziwika bwino yopangira nayitrogeni m'mafakitale, ndipo nayitrogeni yamadzimadzi imayeretsedwa kudzera mu kukanikizana kwa magawo ambiri, kukulitsa kuzizira ndi njira zina. Zipangizo zochepetsera mpweya wochepa kutentha nthawi zambiri zimagwiritsa ntchito ukadaulo wapamwamba woziziritsa komanso zosinthira kutentha bwino kuti zichepetse kukula kwa zida ndikuwonjezera mphamvu.

Njira yochepetsera kusungunuka kwa mpweya wa vacuum: pansi pa mikhalidwe yochuluka ya vacuum, nayitrogeni ya mpweya imasungunuka pang'onopang'ono pansi pa kukakamizidwa, kotero kuti kutentha kwake kumachepa, ndipo pamapeto pake nayitrogeni yamadzimadzi imapezedwa. Njirayi ingapezeke kudzera mu makina ang'onoang'ono a vacuum ndi ma evaporators, ndipo ndi yoyenera kugwiritsidwa ntchito pamene kupanga nayitrogeni mwachangu kukufunika.

Kuchepetsa nayitrogeni yamadzimadzi yamakampani kuli ndi zabwino izi:

Kusinthasintha: Zipangizo zopangira nayitrogeni yamadzimadzi zomwe zapangidwa pang'ono zimatha kusunthidwa ndikuyikidwa malinga ndi zosowa zenizeni kuti zigwirizane ndi zosowa za nthawi zosiyanasiyana.

Kusunthika: Chipangizochi ndi chaching'ono, chosavuta kunyamula komanso kunyamula, ndipo chimatha kukhazikitsa mwachangu machitidwe opangira nayitrogeni pamalopo.

Kuchita Bwino: Zipangizo zopangira nayitrogeni yamadzimadzi zomwe zimagwiritsidwa ntchito pang'ono nthawi zambiri zimagwiritsa ntchito ukadaulo wapamwamba komanso zosinthira kutentha bwino kuti ziwongolere kugwiritsa ntchito mphamvu moyenera komanso kuchepetsa kugwiritsa ntchito mphamvu.

Kuteteza chilengedwe: Nayitrogeni yamadzimadzi, monga choziziritsira choyera, siipanga zinthu zovulaza ikagwiritsidwa ntchito ndipo ndi yabwino ku chilengedwe.

Njira yopangira nayitrogeni yamadzimadzi imaphatikizapo makamaka masitepe otsatirawa, izi ndi njira yoyambira mwatsatanetsatane:

Kupondereza ndi kuyeretsa mpweya:

1. Mpweya umayamba kupanikizika ndi chokometsera mpweya.

2. Mpweya wopanikizika umaziziritsidwa ndi kuyeretsedwa kuti ukhale mpweya wokonzedwa.

Kusamutsa kutentha ndi kusungunuka kwa madzi:

1. Mpweya wokonzedwa umasinthidwa kutentha ndi mpweya wotentha pang'ono kudzera mu chosinthira kutentha chachikulu kuti upange madzi ndikulowa mu nsanja yogawa.

2. Kutentha kochepa kumachitika chifukwa cha kufalikira kwa mpweya wothamanga kwambiri kapena kufalikira kwa mpweya wothamanga wapakati.

Kugawa magawo ndi kuyeretsa:

1. Mpweya umasungunuka mu fractionator kudzera mu zigawo za thireyi.

2. Nayitrogeni yeniyeni imapangidwa pamwamba pa mzere wapansi wa fractionator.

Kubwezeretsanso mphamvu yozizira ndi zotsatira za mankhwala:

1. Nayitrogeni woyera wotentha pang'ono wochokera ku nsanja yapansi umalowa mu chosinthira kutentha chachikulu ndikubwezeretsa kuchuluka kozizira mwa kusinthana kutentha ndi mpweya wokonzedwa.

2. Nayitrogeni yoyera yotenthedwanso imatuluka ngati chinthu ndipo imakhala nayitrogeni yomwe imafunika ndi dongosolo lotsikira pansi.

Kupanga nayitrogeni wosungunuka:

1. Nayitrogeni yomwe imapezeka kudzera mu njira zomwe zili pamwambapa imasungunukanso madzi m'mikhalidwe inayake (monga kutentha kochepa ndi kuthamanga kwambiri) kuti ipange nayitrogeni yamadzimadzi.

2. Nayitrogeni yamadzimadzi imakhala ndi kutentha kochepa kwambiri, pafupifupi madigiri -196 Celsius, kotero imafunika kusungidwa ndikunyamulidwa pansi pa mikhalidwe yovuta.

Kusungirako ndi kukhazikika:

1. Nayitrogeni yamadzimadzi imasungidwa m'zidebe zapadera, zomwe nthawi zambiri zimakhala ndi mphamvu zabwino zotetezera kuti zichepetse kuchuluka kwa nayitrogeni yamadzimadzi yomwe imatuluka.

2. Ndikofunikira kuyang'ana nthawi zonse kulimba kwa chidebe chosungiramo zinthu ndi kuchuluka kwa nayitrogeni yamadzimadzi kuti muwonetsetse kuti nayitrogeni yamadzimadzi ndi yabwino komanso yokhazikika.
