Cryogenic Air Rabe Nitrogen

Samar da nitrogen na Cryogenic ta hanyar rabuwar iska hanya ce ta samar da nitrogen ta gargajiya tare da tarihin shekaru da yawa.Yana amfani da iska a matsayin ɗanyen abu, wanda aka matsa da kuma tsarkakewa, sannan yana amfani da musayar zafi don sanya iska ta zama iska mai ruwa.Air Liquide galibi cakude ne na ruwa oxygen da nitrogen ruwa, ta yin amfani da wuraren tafasa daban-daban na ruwa oxygen da nitrogen ruwa (a yanayi 1, wurin tafasa na farko shine -183°C, na karshen kuma shine -196°C). , ta hanyar gyaran Liquid Air , Rarrabe su don samun nitrogen.Cryogenic iska rabuwa nitrogen samar da kayan aiki ne hadaddun, maida hankali ne akan babban yanki, high kayayyakin more rayuwa halin kaka, karin lokaci daya zuba jari kayan aiki, high aiki halin kaka, jinkirin samar da iskar gas (12-24h), high shigarwa bukatun, da kuma dogon sake zagayowar.M kayan aiki, shigarwa da abubuwan abubuwan more rayuwa, kayan aiki da ke ƙasa 3500Nm3 / h, ma'auni na saka hannun jari na na'urar PSA na ƙayyadaddun ƙayyadaddun 20% -50% ƙasa da na na'urar rabuwar iska ta cryogenic.Cryogenic iska rabuwa nitrogen samar da kayan aiki ne dace da manyan-sikelin masana'antu nitrogen samar, yayin da matsakaici da kuma kananan-sikelin nitrogen samar ne uneconomical.
