System and method for producing syngas

Abstract

Syngas is produced from hydrocarbons and carbon dioxide. A steam methane reformer is configured to receive a hydrocarbon containing stream and steam, and to produce a first intermediate syngas stream from the hydrocarbon containing stream and the steam. At least a fraction of the hydrogen produced in the steam methane reformer is removed from the first intermediate syngas stream, and fed to a reverse water gas shift reactor in which carbon dioxide is reverse shifted to CO. The resulting CO-containing effluent stream is combined with a second intermediate syngas stream, which is a residue stream from the first intermediate syngas stream from which the fraction of hydrogen has been removed. Unconverted hydrogen which is discharged from the reverse water gas shift reactor, can be reintroduced in the second intermediate syngas stream together with the CO. The combined stream is a final syngas stream.
