Kwicandelo lemizi-mveliso, ijenereyitha ye-nitrogen isetyenziswa kakhulu kwi-petrochemical, i-liquefaction yegesi yendalo, i-metallurgy, ukutya, amayeza kunye nemizi-mveliso ye-elektroniki. Iimveliso ze-nitrogen zejenereyitha ye-nitrogen zingasetyenziswa njengegesi yesixhobo, kodwa zikwasetyenziswa njengezinto zokwenza imveliso yemizi-mveliso kunye ne-refrigerant, eyimfuneko kwimveliso yemizi-mveliso. Inkqubo yejenereyitha ye-nitrogen yahlulwe ngokubanzi kwiintlobo ezintathu: indlela yokwahlula umoya obandayo, indlela yokwahlula i-membrane kunye nendlela yokudibanisa uxinzelelo lwe-molecular sieve (PSA).
Indlela yokwahlula umoya obandayo kukusebenzisa umgaqo owahlukileyo we-oksijini kunye ne-nitrogen emoyeni, kunye nokuveliswa kwe-nitrogen engamanzi kunye ne-oxygen engamanzi ngokusebenzisa umgaqo wokucinezela, ukukhenkceza kunye nokucocwa kobushushu obuphantsi ". Le ndlela inokuvelisa i-nitrogen engamanzi kunye ne-oxygen engamanzi kubushushu obuphantsi, isikali esikhulu semveliso; ingxaki kutyalo-mali olukhulu, olusetyenziswa ngokubanzi kwimfuno ye-nitrogen kunye ne-oxygen kwishishini lesinyithi kunye neekhemikhali.
Indlela yokwahlula i-membrane ngumoya njengezinto eziluhlaza, phantsi kweemeko ezithile zoxinzelelo, kusetyenziswa i-oksijini kunye ne-nitrogen kwi-membrane enamazinga ahlukeneyo okuphuma kwamanzi ukwenza ukwahlula i-oksijini kunye ne-nitrogen?. Le ndlela ineenzuzo zesakhiwo esilula, akukho valve yokutshintsha, umthamo omncinci, njl.njl., kodwa ngenxa yokuba izinto ze-membrane zixhomekeke kakhulu kwiingeniso ezingenisiweyo, ixabiso langoku libiza kakhulu kwaye izinga lokungena liphantsi, ngoko ke isetyenziselwa ikakhulu iinjongo ezikhethekileyo zokuhamba kancinci, njengomatshini wokwenza i-nitrogen ohambayo.
Indlela yokufunxa uxinzelelo lwe-molecular seeve (PSA) ngumoya njengezinto ezikrwada, isihluzo se-carbon molecular njenge-adsorbent, ukusetyenziswa komgaqo wokufunxa uxinzelelo, ukusetyenziswa kwesihluzo se-carbon molecular seeve kwi-oxygen kunye ne-nitrogen adsorption kunye nendlela yokwahlula i-oxygen kunye ne-nitrogen ". Le ndlela ineempawu zokuhamba kwenkqubo elula, inqanaba eliphezulu lokuzenzekela, ukusetyenziswa kwamandla aphantsi kunye nobumsulwa be-nitrogen ephezulu, kwaye yeyona teknoloji isetyenziswa kakhulu. Ngaphambi kokuba umoya ungene kwinqaba yokufunxa yomntu, amanzi asemoyeni kufuneka omiswe ukuze kuncitshiswe ukukhukuliseka kwamanzi kwi-molecular seeve kwaye kwandiswe ubomi benkonzo yesihluzo se-molecular. Kwinkqubo yesiqhelo yemveliso ye-nitrogen ye-PSA, inqaba yokufunxa isetyenziswa kakhulu ukususa umswakama emoyeni. Xa inqaba yokufunxa igcwele ngamanzi, inqaba yokufunxa ivuthelwa ngumoya owomileyo ukuze kufezekiswe ukuhlaziywa kwenqaba yokufunxa.
