Claim One:
1. A method optimizing operation of a chemical looping plant having loops A and B, each having a riser for carrying solid particles entrained in air/gas upward then through a horizontal upper pipeline to a separation unit adapted for separating the solid particles from the fluid, the separation unit provides the solid particles downward through a dip leg to a seal pot, the seal pot selectively sending the solid particles either to the opposite loop through a crossover pipe or through a return leg to a lower pipeline at an interconnection point, the fluid is introduced into the lower pipeline blowing the solid particles up the lower pipeline and back through the riser, the method comprising the steps of: creating a reduced order model (“ROM”) by: creating mass balance equations employing terms for pressure, pressure drop, mass flow, acceleration of air and particles for each of the riser, dip leg and return leg; deleting pressure drop terms for the return leg other than those defining friction; deleting acceleration terms in the return leg; setting the return leg pressure drop due to friction to a constant; providing various inputs (u i ) to the ROM and monitoring outputs (y i ) of the ROM to determine optimum settings for the chemical looping plant; and providing the optimum settings to the chemical looping plant to result in optimum operation of the chemical looping plant.
