Abstract :This study experimentally investigates the purification of synthesis gas using the pressure swing adsorption (PSA) method to isolate H₂. The effects of different pressures and flow rates on adsorption durations has been examined. The lowest adsorption capacity has been observed at 5 bar, while the highest has been recorded at 15 bar. It has been observed that the column adsorption capacity increases with increasing pressure. The results indicate an increase in column retention capacity with pressure. The optimum adsorption duration has been found to be 3 minutes at 5 bar and 9 minutes at 15 bar. Additionally, significant effects of p/f ratio and pressurization direction on H₂ purity has been observed. These findings are consistent with the study’s objective which is to provide insights on optimization of PSA parameters and enhancing hydrogen purity. The results support a broader understanding of PSA technology and potential applications of hydrogen purification in industrial areas and paves the way for further progress. Future research suggests that modeling studies could provide further insights and the use of different adsorbents may enhance H₂ purity.
