pSA o2
Isistimu sase-PSA O2 (Pressure Swing Adsorption Oxygen) sikhulula isibonelo esisodwa kwisezintaba zokusebenza nokuthiwelela amagama, ukuhlanganisa uphawu olungileyo kunye nesiphumo esidingekayo emizuzweni ehlukene lokufakwa ukuthiwelela okwesikhiwo se-oxygen ngalokhu. Isistimu esisisekelwe singafundiswa ukususa oxygen kumoya omnyama ngaphandle kwezinye izigama ezithethelwe ngamashumi amane amabili. Umthetho wesiphi woqala umgca wokuqhuma imoya yomphilo kunye nokuthiwelela kuhluke kwezilayithi zezeolite, okuyifunda ukubheka i-nitrogen ngendlela engazange i-oxygen uzisebenza. Isistimu sikhethe umdlalo wezi-2, okufuneka ukuthiwelela okanyeleyo kwe-oxygen ngeminyaka yokuhlukomelela kunye nokuphumelela komoya. Iziphathiso ezimbili zase-PSA O2 zihlukanisiwe neziqinisekisi zokudibanisa, amasensor wephressha kunye neziqinisekisi zokubona ukuthiwelela, ukusure ukuthiwelela kunye nokusenzenjani kakhulu. Izithombo ezinhlobo ziyahlukanisiwe neziqinisekisi zokuthola, futhi zihlukanisiwe neziqinisekisi zokuthiwelela okanyeleyo kwe-oxygen, okungavalelako ukusetshenziswa kwemibuzo enkulu ezigcinwe kwindawo ye-healthcare, indawo yokusebenzela kunye neziqhuthu zokuthola. Ukubuyekeza kwebhalisi kulandelwe, kunye nokuba amasistimu akhona ngamandla amahhadi labalingana namanye amagama, phakathi kwezilaborethi ezincinci kunye nemingeni engaphezulu eyaziwayo amacubi angamahhadi amakhulu amahhadi.
