Ulwelo lweOxygen kunye neLiquid Nitrogen Plant

Emva kwe-molecular sieve adsorption, umoya okrwada utsalwa kakhulu yi-supercharger. Emva kokupholisa nge-cooler, ingena kwi-heat exchanger engundoqo. Ingxenye yegesi ikhutshwe kwindawo ephakathi kwendawo yokushisa ubushushu kwaye ingena kwi-expander. Emva kokuba omnye umoya ungene kwi-heat exchanger engundoqo, ipholiswe kwi-saturation nge-reflux gas kwaye ingene kwinqaba ephantsi kunye nenani elincinci lolwelo. Umoya emva kwenqaba yokuqala ye-distillation, inqaba malunga ne-36 ~ 38% yomoya ophuculweyo we-oksijini, ukunyanga i-nitrogen engamanzi, umoya olwelo kunye ne-nitrogen engamanzi ngenkunkuma ye-nitrogen kunye ne-nitrogen kwi-supercooler emva kokubanda okubandayo kwinqaba, isibhalo emva koko. i-distillation tower, ezantsi ukwenzela ukucoceka kwe-99.6% ye-oksijini, i-oksijini ephuma kwibhokisi ebandayo, emva kokutshintshwa kobushushu obuphambili emva kobushushu kubasebenzisi be-oxygen compressor drive emva koxinzelelo kwi-3.0 MPa. Ioksijini elulwelo ithathwa ukusuka ezantsi kwinqaba ephezulu kwaye ithunyelwe kwitanki yeoksijini engamanzi. I-Nitrogen ≤10PPmO2 ifunyenwe ukusuka phezulu kwinqaba ephezulu. Emva kokufudumeza kwakhona yi-cooler kunye ne-heat exchanger engundoqo, iphuma kwibhokisi ebandayo kwaye ingena kwi-nitrogen press ukuze ixinzelelwe kwi-2.5mpa ngaphambi kokuba ithunyelwe kumsebenzisi. I-nitrogen engcolileyo ikhutshwe phezulu kwinqaba ephezulu, ihlaziywe ngokutsha nge-cooler kunye ne-heat exchanger enkulu, kwaye iphuma kwibhokisi ebandayo. Emva kokufudumeza yonke indlela kwi-heater yokuvuselela, isetyenziswe njenge-molecular sieve regeneration gas. Enye indlela ithunyelwa kwinqaba yokupholisa amanzi kunye nobushushu obuqhelekileyo bamanzi kutshintshiselwano lobushushu ukubuyisela isixa sokupholisa emva koko ukhuphe ngaphandle.

Itsalwa ukusuka kwinqaba esezantsi amaqhezu argon kwikholamu ekrwada yeargon I ukuya ezantsi komphunga onyuka ukusuka phezulu kwikholamu ekrwada yeargon ndatsalela ezantsi kwekholamu ekrwada yeargon II, emva kwedistillation yeenqaba ezimbini kwikholamu ekrwada yeargon II phezulu argon ekrwada, uninzi argon ekrwada ibe ekrwada argon ikholamu condenser, ulwelo yayingenanto ulwelo olujiniweyo emva kwinqaba argon ekrwada njenge argon inqaba ekrwada ulwelo reflux. Ulwelo wabuyela erhabaxa argon tower II icinezelwe yimpompo argon elulwelo kwaye zondliwa phezulu erhabaxa argon tower II. Iqhezu elulwelo emva kokulungiswa kwinqaba yeargon ekrwada ndibuyela kwinqaba ephezulu ukusuka ezantsi, kwaye inxalenye encinci ye-argon ekrwada ingena kwinqaba ecocekileyo ye-argon emva kwe-liquefier. Emva kokulungiswa kwi-argon tower ecocekileyo, i-argon ecocekileyo efunekayo inokufumaneka phantsi kwe-argon tower ecocekileyo.
