Izitshalo ze-nitrogen ezihlanzekile sezibaluleke kakhulu ezimbonini eziningana njengamakhemikhali, ama-electronics, kanye nezicelo zezokwelapha. I-nitrogen iyingxenye ebalulekile cishe kuzo zonke lezi zimboni, futhi ubumsulwa nekhwalithi yayo idlala indima ebalulekile ekuqinisekiseni ikhwalithi yomkhiqizo wokugcina. Ngakho-ke, ukukhiqiza i-nitrogen yekhwalithi ephezulu kubaluleke kakhulu.
I-Pressure swing adsorption (PSA) ubuchwepheshe obungasetshenziswa ukuhlanza i-nitrogen ngokukhipha umoya-mpilo nokunye ukungcola. I-PSA isuselwe kumgomo wokukhangisa kwegesi ezintweni eziqinile ze-adsorbent. I-adsorbent ikhethwa ngokukhetha ngokusekelwe ekhonweni layo lokukhangisa ama-molecule egesi athakaselayo, kuyilapho ivumela amanye amagesi ukuthi adlule.
Esitshalweni se-nitrogen ehlanzekile, ubuchwepheshe be-PSA bungasetshenziswa ukukhiqiza i-nitrogen noma umoya-mpilo ngokulawula ukukhangiswa kanye nokuncibilika kwama-molecule egesi. Inqubo ihilela ukucindezela umoya ekucindezelweni okucacisiwe nokuwudlulisa embhedeni wempahla ye-adsorbent. I-adsorbent material izokhanga i-oxygen nokunye ukungcola, kuyilapho i-nitrogen idlula embhedeni futhi iqoqwe ku-tank yokugcina.
Impahla ye-adsorbent ingavuselelwa ngokukhulula ukucindezela, okubangela ukuthi ama-molecule egesi ancibilike entweni. I-desorbed gas ibe isikhishwa ohlelweni, futhi i-adsorbent ilungele ukukhangisa omunye umjikelezo wama-molecule egesi.
Enye yezinzuzo eziyinhloko zokusebenzisa ubuchwepheshe be-PSA ezitshalweni ze-nitrogen ezihlanzekile kakhulu ukusebenza kahle kwayo kwezindleko. Ubuchwepheshe be-PSA busebenza kahle kakhulu futhi abudingi izinto eziyinkimbinkimbi noma abasebenzi abakhethekile ukuze busebenze. Ukwengeza, inezindleko eziphansi zokusebenza, njengoba ingadingi noma yimuphi umthombo wamandla wangaphandle ngaphandle komoya ocindezelwe.
Enye inzuzo ukuguquguquka kwayo. Ubuchwepheshe be-PSA bungakhiqiza kokubili i-nitrogen ne-oxygen, kuye ngokuthi i-adsorbent material ekhethiwe. Umoya onomoya-mpilo ungasetshenziswa ezimbonini ezimbalwa ezifana nezicelo zezokwelapha kanye nokushisela, lapho kudingeka khona umoya-mpilo omningi.
Kodwa-ke, ukukhiqiza i-nitrogen ehlanzekile noma i-oxygen ngokusebenzisa ubuchwepheshe be-PSA kudinga ukukhethwa ngokucophelela kwempahla ye-adsorbent. Impahla ye-adsorbent kufanele ibe nokukhetha okuphezulu kwama-molecule egesi anentshisekelo futhi kufanele ifanele izimo zokusebenza zesitshalo se-nitrogen esihlanzekile. Ukwengeza, usayizi nokuma kwento ye-adsorbent kufanele kuthuthukiswe ukuze kuncishiswe ukwehla kwengcindezi nokuqinisekisa ukukhangiswa okufanele.
Sengiphetha, ubuchwepheshe be-PSA buyindlela esebenza kahle kakhulu futhi engabizi kakhulu yokukhiqiza i-nitrogen ehlanzekile noma umoya-mpilo ezitshalweni ze-nitrogen ezihlanzekile. Inikeza izinzuzo ezimbalwa, okuhlanganisa ukuguquguquka kanye nezindleko eziphansi zokusebenza. Kodwa-ke, ukukhetha ngokucophelela kwe-adsorbent material kubalulekile ukuze kuqinisekiswe ukuhlanzeka okufiswayo kanye nekhwalithi ye-nitrogen noma i-oxygen ekhiqizwayo. Ngezinzuzo zayo eziningi, ubuchwepheshe be-PSA buyindlela ekhangayo yezimboni ezidinga ikhwalithi ephezulu, ukunikezwa kwe-nitrogen okuthembekile.
