1. Jenereta ya nayitrogeni yolekanitsa mpweya ya Cryogenic

Chopangira nayitrogeni cholekanitsa mpweya chotchedwa cryogenic air leating ndi njira yachikhalidwe yopangira nayitrogeni ndipo chakhalapo kwa zaka pafupifupi makumi angapo. Pogwiritsa ntchito mpweya ngati zopangira, pambuyo poponderezedwa ndi kutsukidwa, mpweyawo umasungunuka kukhala mpweya wamadzimadzi kudzera mu kusinthana kwa kutentha.

Mpweya wamadzimadzi makamaka ndi chisakanizo cha mpweya wamadzimadzi ndi nayitrogeni wamadzimadzi. Pogwiritsa ntchito mwayi wosiyana pakati pa mpweya wamadzimadzi ndi nayitrogeni wamadzimadzi (pa mpweya umodzi, kutentha kwa mpweya woyamba ndi -183).° C ndi ya yomalizayi ndi -196° C), nayitrogeni imapezeka kudzera mu kugawanitsa mpweya wamadzimadzi. Zipangizo zopangira nayitrogeni wa cryogenic batch ndi zovuta, zimakhala ndi malo akuluakulu, zimakhala ndi ndalama zambiri zomangira, zimafuna ndalama zambiri kamodzi kokha pazida, zimakhala ndi ndalama zambiri zogwirira ntchito, zimapanga mpweya pang'onopang'ono (maola 12 mpaka 24), zimakhala ndi zofunikira kwambiri pakuyika komanso nthawi yayitali. Poganizira zinthu zosiyanasiyana monga zida, kukhazikitsa ndi kumanga, pazida zomwe zili ndi mphamvu ya 3,500 Nm3/h kapena kuchepera, kuchuluka kwa ndalama zomwe zimayikidwa mu PSA mayunitsi ofanana ndi 20% mpaka 50% poyerekeza ndi mayunitsi ogawanitsa mpweya wa cryogenic. Chipangizo chopangira nayitrogeni chogawanitsa cryogenic ndi choyenera kupanga nayitrogeni m'mafakitale akuluakulu, koma sichimawononga ndalama zambiri popanga nayitrogeni wapakati komanso waung'ono.

2. Wopanga nayitrogeni wopangira sefa ya mamolekyulu:

Kupanga nayitrogeni ya PSA ndi njira yomwe imagwiritsa ntchito mpweya ngati zinthu zopangira ndi ma sieve a carbon molecular ngati ma absorbents. Imagwiritsa ntchito mfundo ya pressure swing adsorption ndipo imagwiritsa ntchito ma absorbent osankhidwa a carbon molecular sieves kuti mpweya ndi nayitrogeni zilekanitse nayitrogeni ndi mpweya. Njira iyi ndi mtundu watsopano wa ukadaulo wopanga nayitrogeni womwe unakula mofulumira m'zaka za m'ma 1970.

Poyerekeza ndi njira zachikhalidwe zopangira nayitrogeni, ili ndi njira yosavuta, mphamvu yodziyimira yokha, kupanga mpweya mwachangu (mphindi 15 mpaka 30), kugwiritsa ntchito mphamvu zochepa, kuyera kwa zinthu komwe kumasinthidwa mkati mwa mitundu yosiyanasiyana malinga ndi zosowa za ogwiritsa ntchito, kugwiritsa ntchito bwino ndi kukonza, ndalama zochepa zogwirira ntchito, komanso kuyenerera bwino kwa zida.

3. Jenereta ya nayitrogeni yolekanitsa mpweya ndi nembanemba

Pogwiritsa ntchito mpweya ngati zopangira, pansi pa mikhalidwe ina yopanikizika, mpweya ndi nayitrogeni ndi mpweya wina wokhala ndi makhalidwe osiyanasiyana umalekanitsidwa pogwiritsa ntchito mwayi wosiyana wa kuchuluka kwawo kolowera mu nembanemba.

Poyerekeza ndi zida zina zopangira haidrojeni, ili ndi ubwino wokhala ndi kapangidwe kosavuta, voliyumu yaying'ono, valavu yosinthira, kukonza kochepa, kupanga mpweya mwachangu (mphindi 3), komanso kukulitsa mphamvu mosavuta. Ndi yoyenera makamaka kwa ogwiritsa ntchito ang'onoang'ono omwe ali ndi chiyero cha nayitrogeni cha 98%. Kumbali inayi, pamene chiyero cha nayitrogeni chili pamwamba pa 98%, mtengo wake udzakhala wokwera ndi 15% kuposa makina opanga nayitrogeni a PSA omwe ali ndi mfundo zomwezo.
