Uxinzelelo swing adsorption imveliso nitrogen

isebenzisa umoya njengento ekrwada, i-carbon molecular sieve njenge-adsorbent, isebenzisa umgaqo woxinzelelo lwe-swing adsorption, ukusetyenziswa kwe-carbon molecular sieve ukukhetha i-oksijini kunye ne-nitrogen ukwahlula i-nitrogen kunye ne-oksijini, eyaziwa ngokuba yi-PSA nitrogen.Le ndlela iteknoloji entsha yokuvelisa i-nitrogen eyaphuhliswa ngokukhawuleza kwi-1970s.Xa kuthelekiswa nendlela yokuvelisa i-nitrogen yendabuko, ineenzuzo zokuhamba kwenkqubo elula, iqondo eliphezulu lokuzenzekelayo, ukuveliswa kwegesi ngokukhawuleza (imizuzu eyi-15-30), ukusetyenziswa kwamandla aphantsi, ukucoceka kwemveliso kunokulungelelaniswa kuluhlu olukhulu ngokweemfuno zomsebenzisi, ukusebenza kunye nokugcinwa kulula, kunye nokusebenza Ngeempawu zexabiso eliphantsi kunye nokuguquguquka okunamandla, iyakhuphisana kakhulu kwizixhobo zokuvelisa i-nitrogen engaphantsi kwe-1000Nm3 / h, kwaye ithandwa ngakumbi nabasebenzisi be-nitrogen abancinci nabaphakathi.Imveliso ye-nitrogen ye-PSA ibe lukhetho lokuqala kubasebenzisi be-nitrogen abancinci nabaphakathi.

I-Cryogenic Air Ukwahlula iNitrogen

Ukuveliswa kwe-nitrogen ye-Cryogenic ngokuhlukana komoya yindlela yokuvelisa i-nitrogen yendabuko kunye nembali yamashumi eminyaka.Isebenzisa umoya njengento ekrwada, icinezelwe kwaye icocwe, emva koko isebenzisa ukutshintshiselana ngobushushu ukunyibilikisa umoya ube ngumoya wolwelo.Ulwelo lomoya lungumxube weoksijini elulwelo kunye nenitrogen elulwelo, kusetyenziswa iindawo zokubilisa ezahlukeneyo zeoksijini elulwelo kunye nenitrogen engamanzi (kwi-atmosphere e-1, indawo yokubila yangaphambili yi-183°C, kwaye le yokugqibela yi -196°C) , ngokulungiswa koMoya woLiquid, Bahlule ukuze bafumane initrogen.Izixhobo zokuvelisa initrogen zomoya Cryogenic zokwahlula umoya zintsonkothile, igubungela indawo enkulu, iindleko eziphezulu zeziseko zophuhliso, utyalo-mali lwezixhobo zexesha elinye, iindleko eziphezulu zokusebenza, ukuveliswa kwegesi okucothayo (12-24h), iimfuno zofakelo eziphezulu, kunye nomjikelo omde.Izixhobo ezibanzi, ukufakwa kunye nezinto ezisisiseko, izixhobo ezingaphantsi kwe-3500Nm3 / h, isikali sotyalo-mali lwesixhobo se-PSA senkcazo efanayo yi-20% -50% ephantsi kuneso sixhobo sokwahlula umoya we-cryogenic.Izixhobo zokuvelisa initrogen yomoya yeCryogenic zifanelekile kwimveliso yenitrogen yemizi-mveliso emikhulu, ngelixa imveliso yenitrogen ephakathi kunye nencinci ayinaqoqosho.

IMembrane Air Ukwahlula iNitrogen Production

Ukusebenzisa umoya njengento ekrwada, phantsi kweemeko ezithile zoxinzelelo, ukusetyenziswa kwe-oksijini kunye ne-nitrogen kunye nezinye iigesi ezineepropati ezahlukeneyo kwi-membrane zinemilinganiselo eyahlukeneyo yokungena ukwahlula i-oksijini kunye ne-nitrogen.Xa kuthelekiswa nezinye izixhobo zokuvelisa i-nitrogen, ineenzuzo zesakhiwo esilula, umthamo omncinci, akukho valve yokutshintsha, ukugcinwa okuncinci, ukuveliswa kwegesi ngokukhawuleza (≤3 imizuzu), kunye nokwandiswa kwamandla afanelekileyo.Ifaneleke ngokukodwa ukucoceka kwe-nitrogen ≤ I-98% yabasebenzisi be-nitrogen abaphakathi nabancinci banomlinganiselo ongcono wexabiso ukuya kumsebenzi.Xa ubunyulu be-nitrogen bungaphezulu kwe-98%, ixabiso layo lingaphezulu kwe-15% ephezulu kune-PSA yejenereyitha ye-nitrogen yenkcazo efanayo.
