vpsa vs psa technology
VPSA (Vacuum Pressure Swing Adsorption) na PSA (Pressure Swing Adsorption) technolọjị nwere ike ọzọ maka ndị mmiri ụmụ na ikwu okwu ndị mmiri. Gbasara PSA bụ nnukwu ọdịnala, VPSA mere ike na-eme ka anya mgbe a na-akwado ike na mmiri. PSA mere ihe na-eme pressure changes na-akwado ambient levels na-akwado mmiri ụmụ, na-akwado na pressures n'anya 2 to 4 bar. Nkem na-VPSA na-eme vacuum phase, na-akwado sub-atmospheric pressures, na-akwado na pressures n'anya 0.3 to 0.5 bar absolute. Nke mmiri na-agbakwuo ike na-VPSA systems na-akwado recovery rates na-akwado reduced power consumption. Technolọjị na-eme specialized adsorbent materials na-akwado gas molecules ha na-pressure variations. Na-eme, VPSA systems na-eme multi step cycle maara pressurization, adsorption, depressurization, na vacuum regeneration phases. Nke mmiri na-eme ike na-apụta mmiri ụmụ ha na-ojiịa oxygen from air, na-recovery rates na-akwado 90 percent maara. Technolọjị na-eme applications na-akwado industrial gas production, medical facilities, wastewater treatment plants, na ndị mmiri manufacturing processes na-eji ike na-apụta high purity gases.
