Oxygen transport membrane based advanced power cycle with low pressure synthesis gas slip stream

An oxygen transport membrane based advanced power cycle system comprising:

• a source of high pressure synthesis gas;
• at least one oxygen transport membrane based partial oxidation reactor having one or more oxygen transport membrane elements and one or more metal tubes containing the synthesis gas and disposed adjacent or juxtaposed to the one or more oxygen transport membrane elements, the at least one oxygen transport membrane based partial oxidation reactor configured to heat the synthesis gas stream in the metal tubes via indirect heat exchange with a first source of radiant heat generated from a partial oxidation of a low pressure synthesis gas slip stream with oxygen permeated through the one or more oxygen transport membrane elements, and wherein the partial oxidation further produces a reaction product stream and the first source of radiant heat;
• at least one expander disposed downstream of the at least one oxygen transport membrane based partial oxidation reactor, the expander configured to expand the heated synthesis gas stream to produce energy and reduce the pressure of the synthesis gas stream;
• a recycle conduit configured to divert a portion of the expanded synthesis gas stream to the at least one oxygen transport membrane based partial oxidation reactor where such diverted portion of the synthesis gas stream is the low pressure synthesis gas slip stream that is partially oxidized with the permeated oxygen;
• an oxygen transport membrane based boiler having one or more oxygen transport membrane elements and one or more steam tubes containing the boiler feed water and disposed adjacent or juxtaposed to the one or more oxygen transport membrane elements in the oxygen transport membrane based boiler, the oxygen transport membrane based boiler configured to heat the boiler feed water in the steam tubes to produce steam via indirect heat exchange with a second source of radiant heat generated from a combustion of the low pressure synthesis gas with oxygen permeated through the one or more oxygen transport membrane elements, and wherein the combustion produces the second source of radiant heat;
• wherein the oxygen transport membrane based boiler is further configured to combust any expanded synthesis gas stream with a source of supplemental oxygen to produce a carbon dioxide containing flue gas and to further heat the boiler feed water in the steam tubes to produce steam;
• and
• a steam turbine subsystem operatively associated with the oxygen transport membrane based boiler and configured to convert the steam to electrical power.
