umaxhobo wesezintsha lwe-VPSA
I-VPSA (Vacuum Pressure Swing Adsorption) izingu lwenqanawe kwindawo yomtheleli wokusebenzisa ngokubanzi kwi-technology yesibhakabhaka sasemphakathini, elibekelwe ukuthi lokhu kuhlala kusenzo esikhethiswayo nge-oxygen. Isistimu esingaphambili lesikhulula imibhalo yokuphakamisa amagase ngokusebenzisa i-material ezindwendwe zokuphakamisa umthonyama ukusukela okwesiphumo sesikhephe sezingaphambili ukusukela okwesipho sesikhathi. Izingu lingahlukene namandla amabili amalungiselelo amafihlwe ngokubhekelela ukusukela okwesikhathi phakathi kwamandla, ukuvumela ukuhlukaniswa kwe-nitrogen ngokushesha kunye nokulandelana ne-oxygen. Ukusebenza kwi-VPSA kulandelana nezi-zile zokuqinisekisa kahle kakhulu ngokubonisa ukuthi isistimu sikhethe izimbali zokusebenza ezifanele kakhulu ngokuhlukelela kwezi-PSA ezithile. Isistimu singahlukene namandla amaphrofeshoneli amancane okusebenzisa ukubheka, ukuvumela ukusebenza kakhulu kunye nokuhlukaniswa kwekhona lemfano. Ngenxa yalokho kokuthi i-production capacities zizihamba kusasa kanye nokuthi zihamba kwezindlela ezilimi, i-VPSA izingu ziqhuba i-oxygen nge-purity levels ezintathu usuku kunye nokuthi zihamba kwezindlela ezilimi, ukuthi zihlale kusenzo esikhethiswayo ngezinto eziphakeme zokugcina, ngezinhlangano zokusebenza ze-steel kunye nezinye izindawo ezinikezela izinto ezimnandi.
