【Abstract】 In the present work the data of N2/O2 adsorption equilibrium were measured by the laboratory setup of dynamic adsorption and were applied on the simulation of two - bed pressure swing adsorption (PSA) process for O2 product from Air in lab scale. The effects on O2 purity,recovery and productivity of adsorption pressure, adsorption time, purge time, feed flow rate and P/F ratio were discussed in the modeling of O2 PSA, and it is helpful for the design of PSA for O2 product from air.更多还原
