1. Cryogenic iska rabuwa nitrogen janareta
The cryogenic iska rabuwa nitrogen janareta ne na gargajiya nitrogen samar da kuma yana da tarihi na kusan shekaru da dama. Yin amfani da iska a matsayin ɗanyen abu, bayan matsawa da tsarkakewa, ana shayar da iskar cikin iska mai ruwa ta hanyar musayar zafi.
Ruwan iska shine gauraye na ruwa oxygen da ruwa nitrogen. Ta hanyar amfani da bambance-bambancen wuraren tafasa tsakanin ruwa oxygen da ruwa nitrogen (a 1 yanayi matsa lamba, tafasar batu na tsohon -183).° C kuma na karshen shine -196° C), ana samun nitrogen ta hanyar rabuwar ruwa ta iska. Kayan aikin samar da nitrogen na cryogenic yana da rikitarwa, yana mamaye babban yanki, yana da tsadar gini, yana buƙatar babban saka hannun jari na lokaci ɗaya a cikin kayan aiki, yana da tsadar aiki, yana samar da iskar gas a hankali (12 zuwa 24 hours), yana da buƙatun shigarwa da tsayi mai tsayi. Yin la'akari da dalilai daban-daban kamar kayan aiki, shigarwa da ginawa, don kayan aiki tare da damar 3,500 Nm3 / h ko žasa, ma'auni na saka hannun jari na raka'a PSA na ƙayyadaddun ƙayyadaddun abu shine 20% zuwa 50% ƙasa da na sassan rabuwar iska na cryogenic. The cryogenic rabuwa nitrogen samar na'urar ya dace da manyan-sikelin masana'antu nitrogen samar, amma ba tattalin arziki ga matsakaici da kuma kananan-sikelin samar da nitrogen.
2. Molecular sieve nitrogen janareta:
Samar da nitrogen ta PSA hanya ce da ke amfani da iska a matsayin albarkatun ƙasa da kuma sieves na ƙwayoyin carbon a matsayin adsorbents. Yana ɗaukar ka'idar adsorption na matsa lamba kuma yana amfani da zaɓin adsorption na sieves na ƙwayoyin carbon don oxygen da nitrogen don raba nitrogen da oxygen. Wannan hanyar sabuwar nau'in fasaha ce ta samar da nitrogen wacce ta haɓaka cikin sauri a cikin 1970s.
Idan aka kwatanta da hanyoyin samar da nitrogen na gargajiya, yana fasalta tsari mai sauƙi, babban digiri na atomatik, samar da iskar gas mai sauri (minti 15 zuwa 30), ƙarancin amfani da makamashi, tsabtace samfurin daidaitacce a cikin kewayon fa'ida bisa ga buƙatun mai amfani, aiki mai dacewa da kiyayewa, ƙarancin farashin aiki, da dacewa da kayan aiki mai kyau.
3. Membrane iska rabuwa nitrogen janareta
Yin amfani da iska a matsayin albarkatun ƙasa, a ƙarƙashin wasu yanayi na matsa lamba, oxygen da nitrogen da sauran iskar gas tare da kaddarorin daban-daban sun rabu ta hanyar yin amfani da nau'o'in nau'i daban-daban a cikin membrane.
Idan aka kwatanta da sauran kayan aikin samar da hydrogen, yana da abũbuwan amfãni na sauƙi mai sauƙi, ƙananan ƙararrawa, babu bawul mai sauyawa, ƙananan kulawa, samar da iskar gas mai sauri (minti 3), da kuma fadada damar da ya dace. Ya dace musamman ga ƙananan masu amfani tare da tsabtar nitrogen na 98%. A gefe guda kuma, lokacin da tsabtar nitrogen ke sama da 98%, farashin zai kasance sama da 15% sama da na injin samar da nitrogen na PSA na ƙayyadaddun bayanai.
