1. An oxygen transport membrane panel for transferring radiant heat to a plurality of catalytic reforming reactors, the oxygen transport membrane panel comprising:
- a panel frame; and
a plurality of oxygen transport membrane repeating units arranged in a tightly packed linear or co-planar orientation;
wherein each oxygen transport membrane repeating unit comprises two or more oxygen transport membrane tubes coupled together and configured to be in fluid communication with either a feed manifold or an exhaust manifold; and
wherein each oxygen transport membrane tube having a permeate side located on an interior surface of the tube and a retentate side located on an exterior surface of the tube;
wherein the plurality of oxygen transport membrane repeating units are supported by said panel frame and are configured to separate oxygen from an oxygen containing stream contacting the retentate side of the tubes in cross-flow arrangement and react the permeated oxygen with a gas stream containing hydrogen and carbon containing species introduced into the permeate side of the tubes thereby producing radiant heat and a steam containing reaction product stream;
wherein the catalytic reforming reactors are configured to produce synthesis gas in the presence of the radiant heat and a hydrocarbon containing reactant stream optionally containing the reaction product stream from the oxygen transport membrane panels; and
wherein the catalytic reforming reactors are arranged in a plane substantially parallel to the oxygen transport membrane panels.
