METHOD AND SYSTEM FOR PRODUCING A SYNTHESIS GAS IN AN OXYGEN TRANSPORT MEMBRANE BASED REFORMING SYSTEM

摘要

A method and system for producing a synthesis gas in an oxygen transport membrane based reforming system that utilizes a combined feed stream (200) having a steam to carbon ratio between about 1.6 and 3.0 and a temperature between about 500 °C and 750 °C wherein the oxygen transport membrane based reforming system and associated synthesis production process equipment are substantially free of carbon formation and metal dusting corrosion. The combined feed stream is comprised a pre-reformed hydrocarbon feed (195), superheated steam (180), and a reaction product stream (198) created by the reaction of a hydrogen containing stream (163) reacted with the permeated oxygen at the permeate side of the oxygen transport membrane elements (120).
