Production of hydrogen-rich fuel-gas with reduced coemission

Abstract

An H-rich fuel gas stream can be advantageously produced by reforming a hydrocarbon/steam mixture in to produce a reformed stream, followed by cooling the reformed stream in a waste-heat recovery unit to produce a high-pressure steam stream, shifting the cooled reformed stream a first shifted stream, cooling the first shifted stream, shifting the cooled first shifted stream to produce a second shifted stream, cooling the second shifted stream, abating water from the cooled second shifted stream to obtain a crude gas mixture stream comprising Hand CO, and recovering a COstream from the crude gas mixture stream. The H-rich stream can be advantageously combusted to provide thermal energy needed for residential, office, and/or industrial applications including in the H-rich fuel gas production process. The H-rich fuel gas production process can be advantageously integrated with an olefins production plant comprising a steam cracker.
