NOVELTY - Hydrogen-enriched fuel gas and carbon dioxide are generated by, converting hydrocarbon molecules from a gaseous hydrocarbon feed stream into hydrogen and carbon dioxide; separating the hydrogen and carbon dioxide; blending the hydrogen back into the gaseous hydrocarbon feed stream to generate a hydrogen-enriched fuel gas; and utilizing the carbon dioxide for storage or sequestration.    USE - Method of generating hydrogen-enriched fuel gas and carbon dioxide (claimed).    ADVANTAGE - The method generates carbon dioxide, and hydrogen-enriched fuel gas that produces less carbon dioxide per energy unit output when combusted than non-hydrogen-enriched natural gas. The total carbon dioxide compression requirements for the storage or sequestration are reduced by 50-75% as compared to chemical or physical solvent-based carbon dioxide recovery processes that do not utilize the carbon dioxide recovery solvent.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a system for generating hydrogen-enriched fuel gas and carbon dioxide, comprising an inlet handling system; a syngas and water-gas shift system; a water-gas compression system; a carbon dioxide recovery system; a dehydration system; and a carbon dioxide compression system; and    (2) a method of generating hydrogen and carbon dioxide, comprising converting hydrocarbon molecules from a gaseous hydrocarbon feed stream into hydrogen and carbon dioxide; separating the hydrogen and carbon dioxide; utilizing the hydrogen as a separate product; and utilizing the carbon dioxide for storage or sequestration.    The inlet handling system prepares a gaseous hydrocarbon feed stream having a pressure and a temperature to be fed to the syngas and water-gas shift system by removing liquids and solids, reducing the pressure of the gaseous hydrocarbon feed stream, and maintaining the temperature of the gaseous hydrocarbon stream for downstream processes. The syngas and water-gas shift system produces hydrogen-bearing syngas by reforming the gaseous hydrocarbon feed stream into hydrogen and carbon monoxide and then converts the carbon monoxide to carbon dioxide, producing a water-gas stream. The carbon dioxide recovery system has an operating pressure. The water-gas compression system compresses the water-gas stream from the syngas and water-gas shift system to the operating pressure of the carbon dioxide recovery system. The carbon dioxide recovery system separates the carbon dioxide from the hydrogen contained in the water-gas stream produced by the syngas and water-gas shift system. The dehydration system removes water vapor present in the water-gas stream produced by the syngas and water-gas shift system, recovering additional carbon dioxide. The carbon dioxide compression system compresses the carbon dioxide recovered from the water-gas stream by the carbon dioxide recovery system and the dehydration system to a carbon dioxide delivery pressure. The carbon dioxide is separated from the hydrogen using a carbon dioxide recovery solvent. The carbon dioxide recovery solvent comprises butanes, pentanes, hexanes, heptanes, octanes, aromatics, or isomers of butanes, pentanes, hexanes, heptanes, octanes and aromatics.
