Processes and apparatuses for reducing molecular weight fluctuation in a tail gas stream from a pressure swing adsorption process. Multiple PSA separation zone are synchronized such that when one of the PSA units is generating a low molecular weight tail gas, there is another PSA unit generating a high molecular weight tail gas.
