Nayitrogeni yopanga mamolekyulu

Mu mafakitale, jenereta ya nayitrogeni imagwiritsidwa ntchito kwambiri mu petrochemical, liquefaction ya gasi lachilengedwe, metallurgy, chakudya, mankhwala ndi zamagetsi. Zinthu za nayitrogeni zomwe zimapangidwa ndi jenereta ya nayitrogeni zingagwiritsidwe ntchito ngati mpweya wa zida, komanso ngati zipangizo zopangira mafakitale ndi refrigerant, zomwe ndi zida zofunika kwambiri pagulu popanga mafakitale. Njira yopangira jenereta ya nayitrogeni imagawidwa m'mitundu itatu: njira yolekanitsa mpweya wozizira kwambiri, njira yolekanitsa nembanemba ndi njira yosinthira kupanikizika kwa molecular sieve (PSA).
Njira yolekanitsira mpweya wozizira kwambiri ndikugwiritsa ntchito mfundo zosiyanasiyana za mpweya ndi nayitrogeni mumlengalenga, komanso kupanga nayitrogeni wamadzimadzi ndi mpweya wamadzimadzi kudzera mu mfundo ya kupsinjika, kuzizira ndi kusungunuka kwa kutentha kochepa ". Njirayi imatha kupanga nayitrogeni wamadzimadzi ndi mpweya wamadzimadzi wochepa kutentha, kupanga kwakukulu; vuto lake ndi ndalama zambiri, zomwe nthawi zambiri zimagwiritsidwa ntchito pakufunikira kwa nayitrogeni ndi mpweya mumakampani opanga zitsulo ndi mankhwala.
Njira yolekanitsira nembanemba ndi mpweya ngati zinthu zopangira, pansi pa mikhalidwe ina yopanikizika, pogwiritsa ntchito mpweya ndi nayitrogeni mu nembanemba yokhala ndi kuchuluka kosiyanasiyana kwa mpweya ndi nayitrogeni kuti apange kulekanitsa mpweya ndi nayitrogeni?. Njirayi ili ndi ubwino wa kapangidwe kosavuta, palibe valavu yosinthira, voliyumu yaying'ono, ndi zina zotero, koma chifukwa chakuti zinthu za nembanemba zimadalira kwambiri zinthu zomwe zimatumizidwa kunja, mtengo wamakono ndi wokwera mtengo ndipo kuchuluka kwa kulowa kwake ndi kochepa, kotero imagwiritsidwa ntchito makamaka pazinthu zapadera zoyenda pang'ono, monga makina oyenda ndi nayitrogeni.
Njira yogwiritsira ntchito mphamvu ya molekyulu ya sefa (PSA) ndi mpweya ngati zopangira, sefa ya molekyulu ya kaboni ngati adsorbent, kugwiritsa ntchito mfundo yogwiritsira ntchito mphamvu ya kaboni, kugwiritsa ntchito sefa ya molekyulu ya kaboni pogwiritsira ntchito mpweya ndi nayitrogeni komanso njira yolekanitsa mpweya ndi nayitrogeni. Njirayi ili ndi makhalidwe osavuta kuyenda kwa njira, mphamvu zambiri zodziyimira pawokha, kugwiritsa ntchito mphamvu zochepa komanso kuyera kwambiri kwa nayitrogeni, ndipo ndi ukadaulo wogwiritsidwa ntchito kwambiri. Mphepo isanalowe mu nsanja ya anthu yogwiritsira ntchito, madzi omwe ali mumlengalenga ayenera kuumitsidwa kuti achepetse kuwonongeka kwa madzi pa sefa ya molekyulu ndikuwonjezera moyo wa ntchito ya sefa ya molekyulu. Mu njira yachikhalidwe yopangira nayitrogeni ya PSA, nsanja yowumitsa imagwiritsidwa ntchito nthawi zambiri kuchotsa chinyezi mumlengalenga. Nsanja yowumitsa ikadzazidwa ndi madzi, nsanja yowumitsa imabwezeretsedwa ndi mpweya wouma kuti nsanja yowumitsa ibwezeretsedwe.
