Case # | Description |
---|---|
Case 1 | A simple integration where H2 from MA-CLR is fed to the added combustor after the CLC reactors. |
Case 2 | Case 1 with an additional coupling by using part of the CLC fuel reactor flue gas as a steam source for reforming in MA-CLR. |
Case 3 | Using all the CLC fuel reactor flue gas as a steam source for reforming in MA-CLR and producing excess H2 for export. |
Case 4 | Combining CLC and MA-CLR into a single reactor unit and using a 2-phase flow heat exchanger to raise steam from the steam condensation enthalpy in the fuel reactor outlet stream. |
Case 5 | Case 4 produces excess H2 and Case 5 was formulated to produce only power by sweeping the membranes with additional steam to extract more heat from the reactor. |
