1. Chidule cha zida za nayitrogeni zoyera kwambiri
Zipangizo za nayitrogeni zoyera kwambiri ndiye gawo lalikulu la makina olekanitsa mpweya wa cryogenic (cryogenic air separation). Zimagwiritsidwa ntchito makamaka kulekanitsa ndi kuyeretsa nayitrogeni kuchokera mumlengalenga, ndipo pamapeto pake zimapeza zinthu za nayitrogeni zoyera mpaka **99.999% (5N) kapena kuposa pamenepo**. Zipangizozi zimachokera ku ukadaulo wa **cryogenic distillation**, pogwiritsa ntchito kusiyana kwa ma boiling point pakati pa nayitrogeni (boiling point -195.8℃) ndi mpweya (boiling point -183℃) mumlengalenga, ndipo zimapatukana bwino kudzera mu condensation ndi fractionation yotsika kutentha.

Zipangizo za nayitrogeni zoyera kwambiri zimagwiritsidwa ntchito kwambiri m'mafakitale a zamagetsi, mankhwala, mankhwala, kukonza zitsulo, kusunga chakudya ndi zina, makamaka m'mafakitale apamwamba monga kupanga ma semiconductor ndi kupanga mabatire a lithiamu, omwe ali ndi zofunikira kwambiri pakuyeretsa nayitrogeni, ndipo ukadaulo wolekanitsa mpweya wa cryogenic pakadali pano ndiye njira yokhazikika komanso yotsika mtengo kwambiri.

2. Zinthu zazikulu za zida za nayitrogeni zoyera kwambiri
1). Kutulutsa kwa nayitrogeni koyera kwambiri
- Nsanja yothira madzi yokhala ndi magawo ambiri komanso ukadaulo wothira madzi pogwiritsa ntchito sieve ya molecular sieve wothandiza kwambiri ukhoza kupanga nayitrogeni woyeretsedwa bwino wa 99.999% ~ 99.9999% (5N ~ 6N) kuti ikwaniritse zofunikira za semiconductor, photovoltaic ndi mafakitale ena.
- Mpweya wochepa, chinyezi ndi ma hydrocarbon zimachotsedwanso kudzera mu cryogenic adsorption (PSA) kapena ukadaulo wochotsa mpweya m'thupi kuti zitsimikizire kuti nayitrogeni ili bwino.

2) Kusunga mphamvu komanso kugwira ntchito bwino komanso kokhazikika
- Zipangizo zolekanitsa mpweya zomwe zimagwiritsidwa ntchito pogwiritsa ntchito cryogenic air leating zimagwiritsa ntchito expander + heat exchanger kuti zithandizire bwino nthawi yoziziritsira ndikuchepetsa kugwiritsa ntchito mphamvu. Poyerekeza ndi ukadaulo wolekanitsa ndi membrane kapena pressure swing adsorption (PSA), mtengo wogwirira ntchito kwa nthawi yayitali ndi wotsika.
- Dongosolo lowongolera lokha limayang'anira kutentha, kuthamanga ndi kuyera nthawi yeniyeni kuti zitsimikizire kuti zida zikugwira ntchito bwino komanso kuchepetsa kugwiritsa ntchito kwamanja.

3). Kapangidwe ka modular, kusinthasintha kwamphamvu
- Zipangizo zazing'ono za nayitrogeni (<100Nm³/h), zapakati (100~1000Nm³/h) kapena zazikulu (>1000Nm³/h) zitha kusinthidwa malinga ndi zosowa za makasitomala, mogwirizana ndi zosowa za mafakitale osiyanasiyana.
- Yoyenera kupanga nayitrogeni pamalopo (Kupanga pamalopo), kuchepetsa ndalama zoyendera ndi kusunga nayitrogeni yamadzimadzi.

4). Yotetezeka komanso yodalirika, yosamalira chilengedwe komanso yosagwiritsa ntchito kwambiri
- Gwiritsani ntchito kapangidwe kake kosaphulika komanso njira zambiri zodzitetezera (monga kuyang'anira kuchuluka kwa mpweya, chitetezo cha kupanikizika kwambiri) kuti muwonetsetse kuti zinthu zikuyenda bwino.
- Magetsi ndi mpweya zokha ndi zomwe zimagwiritsidwa ntchito panthawi yolekanitsa mpweya wozizira kwambiri, popanda kuipitsa mankhwala, mogwirizana ndi miyezo yopangira zinthu zobiriwira.

3. Madera akuluakulu ogwiritsira ntchito zida za nayitrogeni zoyera kwambiri
1). Makampani a zamagetsi ndi ma semiconductor
- Amagwiritsidwa ntchito popanga ma wafer, ma LED packaging, kupanga ma cell a photovoltaic, kupereka nayitrogeni yoyera kwambiri ngati mpweya woteteza kuti usawonongeke komanso kuipitsidwa.
- Mu semiconductor etching, chemical vapor deposition (CVD) ndi njira zina, nayitrogeni imagwiritsidwa ntchito ngati mpweya wonyamula kapena mpweya woyeretsa kuti zitsimikizire kuti njirayo ndi yokhazikika.

2). Makampani a Mankhwala ndi Mphamvu
- Amagwiritsidwa ntchito poteteza mpweya wosagwira ntchito m'mafakitale opanga mankhwala a petrochemical ndi malasha kuti apewe zoopsa zomwe zingayake komanso kuphulika.
- Amagwiritsidwa ntchito popanga mabatire a lithiamu (monga kuumitsa pole piece, kuyikapo jakisoni wamadzimadzi) kuti ateteze chinyezi ndi mpweya kuti zisakhudze magwiridwe antchito a batire.

3). Makampani Ogulitsa Zakudya ndi Mankhwala
- Ma phukusi a chakudya amagwiritsa ntchito nayitrogeni woyeretsedwa kwambiri (woposa 99.9%) kuti awonjezere nthawi yogwiritsira ntchito ndikuletsa kuwonongeka kwa okosijeni.
- Amagwiritsidwa ntchito mumakampani opanga mankhwala podzaza nayitrogeni ndi kuteteza zinthu zamoyo, mogwirizana ndi miyezo ya GMP.

4). Chithandizo cha Kutentha kwa Chitsulo ndi Kusindikiza kwa 3D
- Kupereka malo opanda mpweya pomangirira, kuzimitsa, kupangira zitsulo ndi njira zina kuti chitsulo chisawonongeke.
- Amagwiritsidwa ntchito posindikiza zitsulo za 3D (ukadaulo wa SLM) kuti achepetse kukhuthala kwa ufa ndikuwonjezera ubwino wa utomoni.

5). Kafukufuku wa Sayansi ndi Laboratory
- Perekani malo a nayitrogeni oyera kwambiri kuti muyesere zinthu zapamwamba monga zinthu zopangira zinthu zambiri komanso nuclear magnetic resonance (NMR).

4. Zochitika zamtsogolo pa chitukuko
1). Kuphatikizika kwa Intelligence ndi Internet of Things (IoT)
- Kupititsa patsogolo kugwiritsa ntchito bwino mphamvu zamagetsi ndi luso lokonzekera zinthu mwanzeru kudzera mu kuyang'anira kutali ndi kukonza bwino AI.
2). Ukadaulo wobiriwira komanso wogwiritsa ntchito mpweya wochepa
- Kuphatikiza ndi mphamvu zongowonjezwdwanso (monga mphamvu ya mphepo, photovoltaic) kuti muchepetse mpweya woipa.
3). Kuchepetsa kupanga kwa nayitrogeni ndi kuyenda
- Pangani zida zopangira nayitrogeni yopyapyala kwambiri yoyenera kugwiritsa ntchito mphamvu zogawika komanso mafakitale ang'onoang'ono.

Chidule
Monga njira yofunika kwambiri yogwiritsira ntchito ukadaulo wolekanitsa mpweya wa cryogenic, zida za nayitrogeni zoyera kwambiri zakhala zida zazikulu zopangira zinthu zamakono komanso zopangira mafakitale ndi zabwino zake monga kuyera kwambiri, kusunga mphamvu ndi kukhazikika, chitetezo ndi kuteteza chilengedwe. Ndi chitukuko chachangu cha mafakitale monga zamagetsi ndi mphamvu zatsopano, zida za nayitrogeni zoyera kwambiri zipitiliza kusintha kukhala zanzeru, magwiridwe antchito komanso zobiriwira, kupereka mayankho odalirika a nayitrogeni m'makampani amakono.
