Claim One:
1. A controller system for optimizing operation of a chemical looping plant having a loop A and a loop B, each of the loop A and the Loop B having respective seal pot valves, and a respective pressure control device, the system comprising: a non-linear model predictive controller (“NMPC”) adapted to: receive a plurality of user setpoints, pressure measurements, solid mass flows and solid levels of both loops A and B; create respective optimum signals for the respective seal pot valves of loop A; create respective optimum signals for the respective pressure control device of loop A; create respective optimum signals for the respective seal pot valves of loop B; create respective optimum signals for the respective pressure control device of loop B provide to loop A the respective optimum signals for the respective seal pot valves of loop A, and respective optimum signals for the respective pressure control device of loop A, to control the respective seal pot valves and the respective pressure control device of loop A; provide to loop B the respective optimum signals for the respective seal pot valves of loop B, and respective optimum signals for the respective pressure control device of loop B, to control the respective seal pot valves and respective pressure control device of loop B; an observer adapted to: receive pressure and differential pressure measurements from loops A and B; calculate solids mass flow and solids levels in loops A and B, and provide the calculated solids mass flow and solids levels of loops A and B to the NMPC.
