1. A chemical looping plant comprising:

  • a chemical loop system including an oxidizer and a reducer;

    the oxidizer being effective to oxidize reduced solids and transport the oxidized solids to the reducer;

    the reducer being effective to reduce the oxidized solids and transport the reduced solids to the oxidizer; and

    a controller that controls the operation of the chemical looping system, wherein the controller receives input signals indicative of an operational parameter of the chemical loop system and at least one of income generated by the chemical looping system and cost of operating the chemical looping system and, in response to the input signals, provides an output signal to the chemical loop system for controlling and optimizing the operation of the chemical loop system;

    the controller including;

    a model of at least one of the chemical looping system and a component of the chemical looping system, wherein the model characterizes at least one of the multi-phased flows and chemical reactions of the chemical looping system in response to the inputs signal received from the chemical looping system;

    a simulator configured to simulate the operation of the chemical looping system to predict the operation of the chemical looping system based on the characterization of the chemical looping system by the model; and

    an optimizer operative to provide the output signal optimized for operating the chemical looping system based on the characterization of the chemical looping system by the model and at least one of income generated by the chemical looping system and cost of operating the chemical looping system.
