Oxygen, nayitrogeni, argon ndi mpweya ena osowa opangidwa ndi mpweya kupatukana unit chimagwiritsidwa ntchito mu zitsulo, makampani mankhwala, oyeretsera, galasi, mphira, zamagetsi, zaumoyo, chakudya, zitsulo, kulenga mphamvu ndi mafakitale ena.

1. Mfundo yopangira chomera ichi imachokera ku malo otentha osiyanasiyana a mpweya uliwonse mumlengalenga. Mpweya umatsindikitsidwa, woziziritsidwa kale ndikuchotsedwa kwa H2O ndi CO2, kenako uzikhazikika muchotenthetsera chachikulu mpaka utasungunuka. Pambuyo kukonza, kupanga mpweya ndi nayitrogeni akhoza kusonkhanitsidwa.
2. Chomera ichi ndi MS kuyeretsedwa kwa mpweya ndi kulimbikitsa turbine expander ndondomeko. Ndi chomera chodziwika bwino cholekanitsa mpweya, chomwe chimatengera kudzaza zinthu zonse ndikukonzanso kupanga argon.
3. Mpweya waiwisi umapita ku fyuluta ya mpweya kuti ichotse fumbi ndi zonyansa zamakina ndi kulowa mu kompresa ya mpweya wa turbine komwe mpweya umakanizidwa kukhala 0.59MPaA. Kenako imalowa mu air precooling system, pomwe mpweya umakhazikika mpaka 17 ℃. Pambuyo pake, imathamangira ku thanki yotsatsa ya ma molekyulu awiri, omwe akuyenda nawonso, kuti achotse H2O, CO2 ndi C2H2.

* 1. Mukayeretsedwa, mpweya umasakanikirana ndi mpweya wotenthedwanso wowonjezera. Kenako imapanikizidwa ndi compressor yapakati kuti igawidwe mu mitsinje 2. Gawo limodzi limapita ku chotenthetsera chachikulu kuti chizikhazikika ku -260K, ndikuyamwa kuchokera pakatikati pachotenthetsera chachikulu kuti chilowetse makina opangira magetsi. Mpweya wotambasulidwa umabwerera ku chotenthetsera chachikulu kuti utenthedwenso, pambuyo pake, umayenda kupita ku kompresa yolimbikitsa mpweya. Mbali ina ya mpweya imalimbikitsidwa ndi chowonjezera kutentha kwapamwamba, kuzizira, kumapita kumalo otsika owonjezera kutentha. Kenako imapita ku bokosi lozizira kuti izizirike mpaka ~ 170K. Zina mwa izo zikanakhazikikabe, ndipo zimayenderera mpaka pansi pa chigawo chotsika kudzera pa chotenthetsera kutentha. Ndipo mpweya wina umayamwa kuti ukhale wochepa. chowonjezera. Pambuyo kukulitsidwa, imagawidwa m'magawo awiri. Gawo limodzi limapita m'munsi mwa ndime yapansi kuti ikonzedwenso, yotsalayo imabwereranso ku chotenthetsera chachikulu, kenako imathamangira ku chowonjezera mpweya pambuyo potenthedwanso.
2. Pambuyo pokonza m'munsi, mpweya wamadzimadzi ndi nayitrogeni wamadzimadzi ukhoza kusonkhanitsidwa pansi. Nayitrogeni wamadzi wotayira, mpweya wamadzimadzi ndi nayitrogeni wamadzimadzi wamadzimadzi amapita kumtunda kudzera mumpweya wamadzimadzi ndi woziziritsa wa nayitrogeni wamadzimadzi. Imakonzedwanso m'chigawo chapamwamba, pambuyo pake, mpweya wamadzimadzi wa 99.6% woyera ukhoza kusonkhanitsidwa pansi pa chigawo chapamwamba, ndikutulutsidwa mu bokosi lozizira ngati kupanga.
3. Gawo la gawo la argon kumtunda limayamwa kukhala gawo la argon. Pali 2 magawo a crude argon column. Reflux ya gawo lachiwiri imaperekedwa pamwamba pa yoyamba ndi pampu yamadzimadzi monga reflux. Imakonzedwanso muzakudya zopanda pake kuti ipeze 98.5% Ar. 2ppm O2 crude argon. Kenako imaperekedwa pakati pa gawo loyera la argon kudzera pa evaporator. Pambuyo rectification mu ndime koyera argon, (99.999% Ar) madzi argon akhoza kusonkhanitsidwa pansi koyera argon ndime.
4. Zinyalala za nayitrogeni kuchokera pamwamba pa chigawo chakumtunda zimatuluka mu bokosi lozizira kupita ku zoyeretsera monga mpweya wobwezeretsa, mpumulo umapita ku nsanja yozizirira.
5. Nayitrojeni pamwamba pa chigawo chothandizira chapamwamba amachokera mubokosi lozizira monga kupangidwa kudzera muzitsulo zozizira komanso zotentha kwambiri. Ngati safunikira nayitrogeni, ndiye kuti ikhoza kuperekedwa ku nsanja yozizirira madzi. Kuti kuzizira kwa nsanja yozizirira madzi sikukwanira, chiller iyenera kuyikidwa.
