VPSA (Vacuum Pressure Swing Adsorption) ho qala ka bohlokwa jwalo lefelo la sephetho sa gasa ea hlokomelang oxygen. Sebetsing sa jwalo seo, e hlobane ho tsoa ho ya ka ho fumana oxygen ho qetela ma-weather ha air ka mokgwa o fetiswang joang ho hlabola pressure. Sebetsing sa VPSA e ne e nyakanyaka tse pedi le tse neng ea vessels ea llenyenyane, e sebedisitse ho bontsha ho ya ka ho fumana oxygen fa ho beletswe. Ha e boloka, air e ne e tshwarelwa ke sebetsing le e tshenyeletswe, e leng e tla hlokomela nitrogen ho adsorb fa oxygen e tla thibela. Sebetsing e ne e tswa ho vacuum phase ho kubisa adsorbent material ho rebella, e tla ile ho feta kgolobong ea production ea jwalo. Sebetsing sa tse pedi e ne e bile e na le control systems ea ntjha ea bohlokwa joang ho hlokomela performance parameters, ho lula pressure levels, cycle times, le flow rates. Mme le ho tswa ho feta oxygen purity levels ho sena 95%, e tla ile ho tswa ho ya ka ho sebediswa ka lintho tse pedi le tse neng tsa industrial. Ho reka le ho hlokomela bohlokong ba technology e tla ile ho tswa ho ya ka ho sebediswa ka lintho tse pedi le tse neng tsa medical facilities tsa tse pedi le tse neng tsa large-scale industrial operations, ho tswa ho ya ka capacities ea production ea 50 to 15,000 Nm³/h. Sebetsing sa VPSA e ne e bile e na le energy efficiency, e tla ile ho tswa ho ya ka ho sebediswa ka power eo le ho latelang ho feta cryogenic separation methods. Ho tswa ho ya ka ho fumana ho ya ka automated operation e tla ile ho tswa ho ya ka ho hlokomela performance ho latelang maintenance requirements le operational complexity.
