Abstract

A process for the integration of oxygen transport membrane with a coal based DRI process is provided. The process includes introducing a heated, compressed air stream into an oxygen transport membrane separator, thereby producing a permeate stream and a retentate stream, introducing at least a portion of the retentate stream into a fired heater along with a combustion air stream, and introducing at least a portion of the permeate stream into a DRI shaft furnace.
