Abstract
A waste heat recovery system is provided. The waste heat recovery system includes a gas separation apparatus that includes a chamber and at least one membrane positioned within the chamber. The gas separation apparatus is configured to produce a retentate that includes at least a combustible gas and a permeate that includes at least a waste gas, wherein the waste gas includes at least a noncombustible gas. Moreover, the waste heat recovery system includes a burner that is coupled to the gas separation apparatus, wherein the burner is configured to receive the permeate and to combust the permeate such that heat is generated from the permeate. Further, a heat recovery steam generator is coupled to the burner and configured to recover heat generated by the burner.
Claims20
A waste heat recovery system for use with a power generation system, said waste heat recovery system comprising:
- a gas separation apparatus comprising a chamber and at least one membrane positioned within said chamber, said chamber having at least a first inlet and at least a first outlet, said gas separation apparatus configured to produce a retentate that includes at least a combustible gas and a permeate that includes at least a waste gas, wherein the waste gas includes at least a noncombustible gas, said first outlet configured to channel the retentate towards a turbine engine;
- a burner coupled to said gas separation apparatus, said burner configured to receive the permeate and to combust the permeate such that heat is generated from the permeate;
- and
- a heat recovery steam generator coupled to said burner and configured to recover heat generated by said burner.
A power generation system comprising:
- at least one turbine engine;
- and
- a waste heat recovery system coupled to said at least one turbine engine, said waste heat recovery system comprising:
- a gas separation apparatus comprising a chamber and at least one membrane positioned within said chamber, said chamber having at least one inlet and at least a first outlet, said gas separation apparatus configured to produce a retentate that includes at least a combustible gas and a permeate that includes at least a waste gas, wherein the waste gas includes at least a noncombustible gas, said first outlet coupled to the at least one turbine engine and configured to channel the retentate towards the at least one turbine engine;
- a burner coupled to said gas separation apparatus, said burner configured to receive the permeate and to combust the permeate such that heat is generated from the permeate;
- and
- a heat recovery steam generator coupled to said burner and configured to recover heat generated by said burner.
A method of using a waste heat, said method comprising:
- separating a mixture of gaseous components via at least one membrane to produce a retentate that includes at least a combustible gas and a permeate that includes at least a waste gas, wherein the waste gas includes at least a noncombustible gas;
- channeling the retentate to a turbine engine;
- channeling the permeate to a burner;
- combusting the permeate via the burner such that heat is generated;
- and
- recovering the heat generated by the burner via a heat recovery steam generator.
