Method and system for producing a synthesis gas in an oxygen transport membrane based reforming system with recycling of the produced synthesis gas
A method and system for producing a synthesis gas in an oxygen transport membrane based reforming system that utilizes a combined feed stream having a steam to carbon ratio between about 1.6 and 3.0 and a temperature between about 500° C. and 750° C. The combined feed stream is comprised a pre-reformed hydrocarbon feed, superheated steam, and a reaction product stream created by the reaction of a hydrogen containing stream reacted with the permeated oxygen at the permeate side of the oxygen transport membrane elements and wherein the hydrogen containing stream is a recycled portion of the synthesis gas.
