The book describes the clean coal technology of chemical looping combustion (CLC) for power generation with pure CO2 capture. The focus of the book is on the modeling and simulation of CLC. It includes fundamental concepts behind CLC and considers all categories of fluidized beds and reactors including a variety of oxygen carriers. The book includes process simulations with Aspen Plus® software using coal, natural gas, and biomass as well as computational fluid dynamics (CFD) simulations using both the Eulerian and Lagrangian methods. It describes various drag models, turbulence models, and kinetics models required for CFD simulations of CLC and covers single reactor, partial, and full-simulations, single/multi-stage as well as single-particle simulations, and CLC with reverse flow. A large number of examples for both process simulations using Aspen Plus and CFD simulations using a variety of fluidized beds/reactors employing both the two-fluid and Computational Fluid Dynamics / Discrete Element Method (CFD-DEM) model are provided.  Modeling and Simulation of Fluidized Bed Reactors for Chemical Looping Combustion will be an invaluable reference for industry practitioners and researchers in academic and industrial R&D currently working on clean energy technologies and power generation with carbon capture.

Geological Carbon Storage (GCS) is one of the most promising technologies to address the issue of excessive anthropogenic CO2 emissions into the atmosphere due to fossil fuel combustion. For GCS, the saline aquifers are considered very attractive compared to other options because of their huge sequestration capacity in U.S. and other parts of the world. However, in order to fully exploit their potential, the injection strategies need to be investigated that can address the issues of both the CO2 storage efficiency and safety along with their economic feasibility. Numerical simulations can be used to determine these strategies before the deployment of full scale sequestration in saline aquifers. This book presents the physical models, numerical simulation techniques and genetic algorithm based optimization method for CO2 sequestration in saline aquifers. Several model examples, benchmark studies as well as examples of actual large scale sequestration efforts in saline aquifers worldwide are presented and compared with available field data. The goal of the book is to provide important insights in physical modeling as well uncertainties associated with the numerical simulation of GCS.
