1. Kupondereza ndi kuyeretsa mpweya

Mpweya umalowa mu air compressor ukachotsa fumbi ndi zinyalala zamakina kudzera mu fyuluta ya mpweya, n’kukanikizidwa kufika pa mphamvu yofunikira, kenako n’kutumizidwa ku air cooler kuti muchepetse kutentha kwa mpweya. Kenako mulowe mu air drying purifier kuti muchotse chinyezi, carbon dioxide, acetylene ndi ma hydrocarbon ena mumlengalenga.

2. Kulekanitsa mpweya

Mpweya woyeretsedwa umalowa mu chosinthira kutentha chachikulu mu nsanja yolekanitsa mpweya, umaziziritsidwa kufika kutentha kokwanira ndi mpweya wa reflux (nayitrogeni wazinthu, mpweya wotayira), ndipo umatumizidwa pansi pa nsanja yokonzanso, komwe nayitrogeni imapezeka pamwamba pa nsanja, ndipo mpweya wamadzi umakokedwa kenako umatumizidwa pansi pa nsanja yokonzanso. Lowani mu evaporator ya condensation kuti isungunuke, ndipo nthawi yomweyo gawo la nayitrogeni wotumizidwa kuchokera ku nsanja yokonzanso, gawo la nayitrogeni wamadzimadzi wochepetsedwa limagwiritsidwa ntchito ngati madzi a reflux a nsanja yokonzanso, ndipo gawo lina limatulutsidwa kuchokera ku nsanja yolekanitsa mpweya ngati chinthu cha nayitrogeni wamadzimadzi.

Mpweya wotulutsa mpweya wochokera ku evaporator yoziziritsa mpweya umatenthedwanso kufika pa 130K ndi chotenthetsera chachikulu ndipo umalowa mu chotenthetsera kuti chiziziziritse kuti chikhale ndi mphamvu yoziziritsira ya nsanja yolekanitsa mpweya. Gawo la mpweya wofutukukawo limagwiritsidwa ntchito pokonzanso ndi kuziziritsa sefa ya molekyulu, kenako nkutulutsidwa mumlengalenga woziziritsira mpweya.

3. Kutulutsa mpweya wa nayitrogeni wamadzimadzi

Nayitrogeni wamadzimadzi wochokera ku nsanja yolekanitsa mpweya amasungidwa mu thanki yosungiramo nayitrogeni wamadzimadzi. Zipangizo zolekanitsa mpweya zikakonzedwanso, nayitrogeni wamadzimadzi womwe uli mu thanki yosungiramo umalowa mu vaporizer ndipo umatenthedwa, kenako umatumizidwa ku payipi ya nayitrogeni yopangidwa.

Kupanga nayitrogeni ya cryogenic kumatha kupanga nayitrogeni yokhala ndi chiyero cha ≧ 99.999%.
