ụdị mmiri vpsa
VPSA (Vacuum Pressure Swing Adsorption) ụwa ahụ nke ike na-ekwu ndị mmiri gara agha, na-enye oge n'ime ndị mmiri gas separation processes, na-abụgharị maka ndị mmiri oxygen na nitrogen. Ndị ụwa siteere na ndị molecular sieve materials ndị mmiri na-agba nitrogen n'ime ndị mmiri atmospheric air, ka ndị mmiri oxygen bụrụta na-eme product. Nke akwụkwọ ga-eji otu ndị ikike: pressurization, n'ezie ndị mmiri air na-agba n'ime ndị bed adsorbent, na vacuum desorption, n'ezie ndị mmiri nitrogen na-agba n'aka. VPSA technology na-enye ndị mmiri ọzọ na-akwado na ndị system cryogenic ndị na-otu na-na-ato, ma na ndị application small to medium-scale. Na-eme na-otu na-akwukwo temperature, ndị ụwa ga-eme energy input ndị na-adịghị, ma na-eme ndị mmiri gas na-high purity. Nke design modular na-enye ndị mmiri ọzọ na-eme installation na-operation, na-enye ha mere ndị ideal n'ime ndị industry ndị na-akwado healthcare facilities, wastewater treatment plants, na manufacturing processes. Na-enye control systems automatic na monitoring capabilities advanced, ndị ụwa VPSA na-eme performance consistent na-adịghị na-eme ndị mmiri operator intervention. Nke efficiency na-enye ndị mmiri ọzọ na-eme rapid cycling capability, na-enye ha mere ndị mmiri continuous gas production na-power consumption lower na-akwado na ndị method conventional.
