PROCESS AND PLANT FOR PRODUCING HYDROGEN-RICH SYNTHESIS GAS STREAM FROM A CARBON-CONTAINING INPUT GAS STREAM

PROCESS AND PLANT FOR PRODUCING HYDROGEN-RICH SYNTHESIS GAS STREAM FROM A CARBON-CONTAINING INPUT GAS STREAM

Provided is a process for producing a hydrogen-rich synthesis gas stream (222, 322) having reduced carbon dioxide emission by reacting a carbon-containing input gas stream (202, 302) in at least one synthesis gas production stage (204, 304) to produce a raw synthesis gas steam (206, 306), producing...

Zusammenfassung:Provided is a process for producing a hydrogen-rich synthesis gas stream (222, 322) having reduced carbon dioxide emission by reacting a carbon-containing input gas stream (202, 302) in at least one synthesis gas production stage (204, 304) to produce a raw synthesis gas steam (206, 306), producing a converted synthesis gas stream (214, 314) by converting the cooled raw synthesis gas steam (210, 310) in a CO conversion plant (212, 312) which comprises at least one CO conversion stage, contacting the cooled converted synthesis gas stream (218, 318) in a carbon dioxide absorption column (220, 320) and discharging a first synthesis gas stream (222, 322) and utilizing at least a portion of the second synthesis gas stream (240, 340) depleted in carbon dioxide as a portion of fuel gas or process gas or forms the fuel gas or process gas.
