The present invention is a method of reducing the carbon dioxide balance from a reformer furnace flue gas to the high pressure syngas exit water gas shift reaction unit. Introducing a heated gas mixture into at least one pre-reforming chamber. The heating being provided by indirect heat exchange with one or more of an SMR furnace flue gas or an SMR furnace syngas introducing the gas mixture into a standard H2 PSA unit, wherein the gas mixture is separated into a hydrogen enriched stream and a PSA tail gas stream; introducing the PSA tail gas stream into a CPU system, wherein the PSA tail gas stream is separated into a carbon dioxide enriched stream, a hydrogen rich stream, and a residual stream, and introducing the residual stream as fuel into the reformer furnace along with natural gas.
A method of reducing the carbon dioxide balance from a reformer furnace flue gas to the high pressure syngas exit water gas shift reaction unit, comprising;
