Emkhakheni wezimboni, ijenereyitha ye-nitrogen isetshenziswa kabanzi embonini ye-petrochemical, igesi yemvelo encibilikayo, i-metallurgy, ukudla, imithi kanye ne-elekthronikhi. Imikhiqizo ye-nitrogen yejenereyitha ye-nitrogen ingasetshenziswa njengegesi yezinsimbi, kodwa futhi njengezinto zokusetshenziswa zezimboni kanye ne-refrigerant, okuyimishini yomphakathi edingekayo ekukhiqizweni kwezimboni. Inqubo yejenereyitha ye-nitrogen ihlukaniswe kakhulu ngezinhlobo ezintathu: indlela yokuhlukanisa umoya obandayo ojulile, indlela yokuhlukanisa i-membrane kanye nendlela yokudonsa ingcindezi yesihlungo sama-molecule (PSA).
Indlela yokuhlukanisa umoya obandayo ojulile ukusebenzisa isimiso esihlukile sokubilisa se-oxygen ne-nitrogen emoyeni, kanye nokukhiqizwa kwe-nitrogen ewuketshezi kanye ne-oxygen ewuketshezi ngokusebenzisa isimiso sokucindezela, ukupholisa kanye nokuhlanza izinga lokushisa eliphansi ". Le ndlela ingakhiqiza i-nitrogen ewuketshezi esezingeni eliphansi kanye ne-oxygen ewuketshezi, isikali esikhulu sokukhiqiza; ububi ukutshalwa kwezimali okukhulu, okuvame ukusetshenziswa ekudingweni kwe-nitrogen ne-oxygen embonini yezinsimbi kanye namakhemikhali.
Indlela yokuhlukanisa ulwelwesi umoya njengokusetshenziswa kwezinto zokusetshenziswa, ngaphansi kwezimo ezithile zokucindezela, kusetshenziswa umoya-mpilo ne-nitrogen kulwelwesi olunezinga lokuphuma elihlukile ukwenza ukuhlukaniswa komoya-mpilo ne-nitrogen?. Le ndlela inezinzuzo zesakhiwo esilula, akukho valve yokushintsha, ivolumu encane, njll., kodwa ngenxa yokuthi izinto zelwelwesi zincike kakhulu ekungenisweni, intengo yamanje iyabiza futhi izinga lokungena liphansi, ngakho-ke isetshenziswa kakhulu ngezinjongo ezikhethekile zokugeleza okuncane, njengomshini wokwenza i-nitrogen ohambayo.
Indlela yokumunca ingcindezi yesihlungo sama-molecule (i-PSA) umoya njengezinto zokusetshenziswa, isihlungo sama-molecule esi-carbon njengesimunca, ukusetshenziswa komgomo wokumunca ingcindezi, ukusetshenziswa kwesihlungo sama-molecule esi-carbon somunca i-oxygen ne-nitrogen kanye nendlela yokuhlukaniswa kwe-oxygen ne-nitrogen “. Le ndlela inezici zokugeleza kwenqubo elula, izinga eliphezulu lokuzenzakalela, ukusetshenziswa kwamandla aphansi kanye nobumsulwa obuphezulu be-nitrogen, futhi ubuchwepheshe obusetshenziswa kakhulu. Ngaphambi kokuba umoya ungene embhoshongweni wokumunca abantu, amanzi emoyeni kumele omiswe ukuze kuncishiswe ukuguguleka kwamanzi esihlungweni sama-molecule futhi kwandiswe impilo yenkonzo yesihlungo sama-molecule. Enqubweni evamile yokukhiqiza i-nitrogen ye-PSA, umbhoshongo wokomisa uvame ukusetshenziswa ukususa umswakama emoyeni. Lapho umbhoshongo wokomisa ugcwele amanzi, umbhoshongo wokomisa upheshulwa umoya owomile ukuze kuqashelwe ukuvuselelwa kombhoshongo wokomisa.
