ba umthengi weseVPSA
Isikhombisa sokuqasha kweVPSA (Vacuum Pressure Swing Adsorption) usetyenziswa njenge-solution esisophutha kwisekhono lokusekelwa kweamasiko, luhlukileyo olungena ukusetyenziswa kokubuyiselwa kweoxygen. Isistimu esisodwa sesetyenziswa leyi-use molecular sieve adsorbents yokubuyisela oxygen kumoya wendawo, ukuze libuyeleye umphilo womncedisi weoxygen eziningi zokusebenza kwi-industri nesikoleni. Isikhombisa sikusebenza ngokushesha kwezinye zeminyaka lokuphumelela nokulayisha, ukuze lihlale lindise oxygen ngokuphelele ngokwesibhedlela sokufundziswa. Amaphrojekthi amandla amahhadi amanamashumi amabili afakwa kuhluke amasistimi akudibanisa, amaxhobo okunquma kwe-pressures kunye nezinto zakudibanisa zokugcina emgquweni, uzokusiza ukusebenza kwakhulu. Izikhombiso zilungene ukuba labe ompiweyo loluntu lwabo eliphi le 90% kwi-95%, ukuze bazingeni izicwangciso ezidingiwe kwekliniki, ukusebenzisa isitshati, ukusebenzisa igilasi kunye nokuphucula amanzi angaphansi. Ukusetha kwezinga lemncedisi kanye nokufundiswa kwezindlela ezinomsindo, uzokususa ukusetha nokufundiswa kunye nokusetyenziswa komncedisi.
