Izityalo zenitrogen ezicocekileyo zibaluleke kakhulu kumashishini aliqela afana neekhemikhali, izinto zombane, kunye nezicelo zonyango. I-nitrojeni licandelo eliphambili phantse kuwo onke la mashishini, kwaye ukucoceka kwayo kunye nomgangatho udlala indima ebalulekileyo ekuqinisekiseni umgangatho wemveliso yokugqibela. Ke ngoko, ukuvelisa initrogen ekumgangatho ophezulu kubaluleke kakhulu.
I-Pressure swing adsorption (PSA) bubuchwepheshe obunokusetyenziswa ukuhlambulula i-nitrogen ngokususa i-oksijini kunye nobunye ukungcola. I-PSA isekelwe kumgaqo we-gas adsorption kwizinto eziqinileyo ze-adsorbent. I-adsorbent ikhethwa ngokukhethiweyo ngokusekelwe kwikhono layo lokubhengeza i-molecule yegesi enomdla, ngelixa ivumela ezinye iigesi ukuba zidlule.
Kwisityalo se-nitrogen esicocekileyo, iteknoloji ye-PSA ingasetyenziselwa ukuvelisa i-nitrogen okanye i-oksijini ngokulawula i-adsorption kunye ne-desorption ye-molecule yegesi. Inkqubo ibandakanya ukunyanzeliswa komoya kuxinzelelo oluchaziweyo kwaye idlulise ngombhede wezinto ze-adsorbent. Izinto ze-adsorbent ziyakubhengeza i-oksijini kunye nezinye izinto ezingcolileyo, ngelixa i-nitrogen idlula ebhedeni kwaye iqokelelwa kwitanki yokugcina.
Isixhobo se-adsorbent sinokuphinda sihlaziywe ngokukhulula uxinzelelo, obangela ukuba ii-molecule zegesi zidibanise kwizinto eziphathekayo. Irhasi ye-desorbed igqithiselwa ngaphandle kwenkqubo, kwaye i-adsorbent ilungele ukubhengeza omnye umjikelo weeathomu zegesi.
Enye yeenzuzo eziphambili zokusebenzisa iteknoloji yePSA kwizityalo zenitrogen ezisulungekileyo kukusebenza kwayo kweendleko. Itekhnoloji yePSA isebenza kakuhle kakhulu kwaye ayifuni zixhobo zintsonkothileyo okanye abasebenzi abakhethekileyo ukuze isebenze. Ukongezelela, ineendleko zokusebenza eziphantsi, njengoko ayifuni nawuphi na umthombo wamandla wangaphandle ngaphandle komoya ocinezelweyo.
Enye ingenelo kukuguquguquka kwayo. Itekhnoloji yePSA inokuvelisa zombini initrogen kunye neoksijini, kuxhomekeke kwizinto ezikhethiweyo ze-adsorbent. Umoya otyetyiswe ngeoksijini ungasetyenziswa kumashishini aliqela afana nezicelo zonyango kunye ne-welding, apho kufuneka i-oksijini ephezulu.
Nangona kunjalo, ukuvelisa i-nitrogen ecocekileyo okanye i-oksijini ngokusebenzisa itekhnoloji ye-PSA kufuna ukukhethwa ngononophelo kwezinto ze-adsorbent. Izinto ze-adsorbent kufuneka zibe nokukhethwa okuphezulu kwi-molecule yegesi enomdla kwaye kufuneka ifaneleke kwiimeko zokusebenza zesityalo se-nitrogen esicocekileyo. Ukongezelela, ubungakanani kunye nokuma kwezinto ze-adsorbent kufuneka ziphuculwe ukunciphisa ukuhla koxinzelelo kunye nokuqinisekisa i-adsorption efanelekileyo.
Ukuqukumbela, itekhnoloji ye-PSA yindlela esebenza kakhulu kwaye eneendleko zokuvelisa initrogen ecocekileyo okanye ioksijini kwizityalo zenitrogen ezicocekileyo. Inika iingenelo ezininzi, kubandakanya ukuguquguquka kunye neendleko eziphantsi zokusebenza. Nangona kunjalo, ukukhethwa ngokucophelela kwezinto ze-adsorbent kubalulekile ukuqinisekisa ukucoceka okufunwayo kunye nomgangatho we-nitrogen okanye i-oxygen eveliswayo. Ngeenzuzo zayo ezininzi, iteknoloji yePSA lukhetho olunomtsalane kumashishini afuna umgangatho ophezulu, unikezelo lwenitrogen oluthembekileyo.
