Abstract
A method for producing a purified carbon dioxide product suitable for EOR and surplus electricity uses a vaporous hydrocarbon feed and a SOFC system. A SOFC system includes a condensate removal system, an acid gas removal system, a hydrodesulfurization system, a sorption bed system, a pre-reformer, a solid oxide fuel cell, a CO2 separations system and a CO2 dehydration system operable to form the purified carbon dioxide product, where the SOFC system is operable to produce surplus electricity from the electricity produced by the solid oxide fuel cell. A method of operating the pre-reformer to maximize the internal reforming capacity of a downstream solid oxide fuel cell uses a pre-reformer fluidly coupled on the upstream side of a solid oxide fuel cell. A method of enhancing hydrocarbon fluid recovery from a hydrocarbon-bearing formation using a SOFC system.
