N'ime VPSA (Vacuum Pressure Swing Adsorption), ụlọ oksigen nwere ike na-akwado technology nke otu ndị mmiri oke oksigen n'asusu adsorption process. System nke otu akwukwo na-echeta molecular sieve materials nke ahu na-akpata nitrogen nke air nke ala, maka o na-ekwu oksigen. Nkweretị na-adịghị mere amalitọ: pressurization na-vacuum desorption. N'anya pressurization, air nke ahụ na-eme ka e mere na molecular sieve beds, ma ọ bụrụ na nitrogen molecules na-akpata, o ha oksigen molecules na-ekwu. N'anya vacuum na-egosi molecular sieve beds na-eme ka e ga-elu nitrogen na-akpata. Cycle nke otu na-eme na-akwado oksigen na-agbakwuo purity levels nke 93-95%. Ụlọ na-egosi vessels nke adsorption na-adịghị mere na-alaejikwa sequences, na-akwado ozi oksigen. Control systems nke ndị mmiri na-echeta na-ajụjụ na na-amama operational parameters, mgbe pressure levels, cycle times, na flow rates, na-akwado optimal performance. Process na-eme energy nke otu ndị na-eme na-oji oge oge method nke ozi oksigen, na-akwadọ ya na-eme ihe otu na-eme na industrial applications. VPSA plants na-eme scale na na-akwadọ ya na-eme ihe otu na-eme na varying ozi oksigen requirements, n'aka small medical facilities na large industrial operations.
