Abstract
Pressure swing adsorption process for reducing fluctuations in the flow rate of tail gas from the adsorption unit and reducing fluctuations in the stoichiometric oxidant flow rate required to completely combust the tail gas in a reformer furnace. Constant flow rate and constant fuel property can be obtained by intelligent mixing designs.
