Teknoloji VPSA (Vacuum Pressure Swing Adsorption) ati PSA (Pressure Swing Adsorption) jẹ́ àwọn ìtàn mẹ́ta tí a dá pápọ̀ ní èdè gas separation ati purification processes. Pada iná ti PSA technology jẹ́ orílẹ̀-èdè, VPSA rí pataki tí ó ṣe pẹlu iye ni awọ́ ati ohun mẹ́ta. PSA ṣe ni iraye lori ọdún láti fihan gas mixtures, típàlù ó ṣe ni iraye tí ó ní 2 to 4 bar. Pẹlu orilẹ-ede, VPSA kọjá vacuum phase, ní iraye tí ó ní sub atmospheric pressures, tí ó ní 0.3 to 0.5 bar absolute. Iraye mẹ́ta tí ó ní yìí lè yíkí VPSA systems ṣe ni higher recovery rates ati reduced power consumption. Teknoloji tí ó ní ìmọ̀ pẹlu specialized adsorbent materials tí ó gbé gas molecules si aláṣe lori iraye variations. Nígbà tí ó ṣe, VPSA systems ṣe ni multi step cycle tí ó ní pressurization, adsorption, depressurization, ati vacuum regeneration phases. Iraye yìí lè yíkí fihan gas mẹ́ta tí ó ní oxygen from air, ní recovery rates tí ó ní 90 percent or higher. Teknoloji tí ó ní ìbúkọ́ ni industrial gas production, medical facilities, wastewater treatment plants, ati various manufacturing processes tí high purity gases jẹ́ ìfihán.
