    Abstract: An apparatus and process for steam reforming can be configured to produce at least one product with reduced carbon dioxide and/or nitrogen oxide emissions. Some embodiments can be better adapted for retrofitting a pre-existing steam reforming process while other embodiments can be better adapted for use in a newly constructed facility. Embodiments can be configured to utilize a synthetic air oxidant to provide combustion that results in formation of a flue gas having relatively high carbon dioxide concentrations that may also have low nitrogen and low nitrogen oxide concentrations. A control system can be configured for utilization in such embodiments to control the steam reforming process and/or oxidant formation process as well. Some embodiments can also be configured to provide carbon dioxide recovery that can permit recovery of a second product stream comprised of carbon dioxide.
