Application Model Overview
Chemical looping combustion (CLC) offers a promising approach to carbon capture by separating fuel combustion from the nitrogen in air. Using a solid oxygen carrier, CLC transfers oxygen between an air reactor and a fuel reactor, enabling combustion that produces a concentrated CO₂ stream for downstream capture.
This Barracuda Virtual Reactor Application Model simulates a coal-fueled CLC system consisting of two reactors, a cyclone, a loop seal, and an L-valve. The model incorporates ilmenite oxygen-carrier particles, detailed oxidation and reduction kinetics, coal gasification, and water-gas shift reactions to capture the coupled hydrodynamic, thermal, and chemical behavior of the system.
Results demonstrate Barracuda’s ability to resolve particle loading, temperature, velocity, and composition throughout the circulating system, while tracking gas-phase species and chemical reaction rates. The model highlights the separation of oxygen and carbon dioxide between the air and fuel reactors—an important feature of CLC for efficient CO₂ capture.
