Four different configurations of pressure swing adsorption (PSA) were designed numerically using Matlab software. The PSA system was applied to separate oxygen from air. The software was used first to validate previous experimental results of single bed adsorber. The results showed that the breakthrough time with product pressurizing is about 1000 s and mass transfer zone (MTZ) is steeper, while with the air pressurizing happened within 60s and MTZ was very wide. High purity of oxygen (>90%) was observed with the first and fourth configuration. Purity of about 88% was achieved with the third configuration, and low purity (75%) with the second configuration. In addition, high power consumption was indicated by the first, and second configurations. However, the third and fourth configurations consumed low power due to the pressure equalization step. Based on the results, the more economic and effective design is the fourth configuration.
