amakhompiya ephakeme kweVPSA
Izixazululo zezitshalo ze-VPSA ezenziwe ngezifiso (i-Vacuum Pressure Swing Adsorption) zimelela indlela eseqophelweni eliphezulu yokuhlukanisa igesi nokuhlanza ubuchwepheshe. Lezi zinhlelo ezintsha zenzelwe ukuhlangabezana nezidingo ezithile zezimboni, zinikeza amandla okwenza umoya-mpilo asebenzayo futhi onokwethenjelwa. Lobu buchwepheshe busebenza ngokusebenzisa ama-molecular sieve adsorbents akhethekile ahlukanisa umoya-mpilo nomoya ozungezile ngenqubo yokucindezela. Lolu hlelo lusebenzisa izindlela zokulawula eziphambili ezilawula imijikelezo ye-vacuum nengcindezi, okuqinisekisa ukusebenza kahle nokuvumelana kwekhwalithi yomkhiqizo. Izitshalo ze-VPSA zenzelwe izingxenye ezihlanganisiwe, ezivumela ukusabalalisa nokuzivumelanisa namakhono ahlukahlukene okukhiqiza asukela ekusebenzeni kwamasayizi amancane kuya ezikhungweni ezinkulu zezimboni. Lobu buchwepheshe buhlanganisa izinhlelo zokuqapha ezihlakaniphile ezinikeza idatha yokusebenza ngesikhathi sangempela nokulungiswa okuzenzakalelayo ukuze kutholakale ukusebenza kahle okuphezulu. Lezi zitshalo zinezinhlelo ezisebenza kahle ezinciphisa kakhulu ukusetshenziswa kwamandla uma kuqhathaniswa nezindlela zendabuko zokuhlukanisa igesi, okwenza zihlale zikhona kokubili imvelo kanye nezomnotho. Izicelo zihlanganisa izimboni eziningi, kuhlanganise ezempilo, ezensimbi, ukukhiqizwa kwengilazi, kanye nokucutshungulwa kwamakhemikhali, lapho umoya-mpilo ohlanzekile ubalulekile ekusebenzeni.
