Pressure swing adsorption time

Issues with pressure swing adsorption time? 5-1-3-v5: Tower 1 is online for adsorption while Towers 3 are used for pressure equalization! Recently, the hydrogen Co content is high! Does changing the pressure swing adsorption time have an effect? What specific times does the modification time refer to? Is it adsorption or equalization time?
First, it is necessary to check whether the carbon monoxide content in the feed gas has increased compared to before. If it is to be increased, it needs to be resolved within the previous system. If there is no increase, fine-tuning will need to be done through PSA operations. When the total amount of gas added remains constant, if the purity of hydrogen drops below the required level, it is necessary to slightly reduce the adsorption time and the operating coefficient, as well as to conduct frequent tests on the carbon monoxide content in the produced hydrogen. Make adjustments based on the results. The consequence of making the above adjustments is a decrease in the hydrogen recovery rate; in other words, the hydrogen content in the purge gas increases.
