PROJECT DESCRIPTION:

The objective of the proposed research is to develop an economically and environmentally acceptable integrated process for disposal of carbon dioxide (CO2) generated by the combustion of fossil fuels in power-generation plants. The method of carbon sequestration in this proposal is mineral carbonation, the reaction of naturally occurring calcium and/or magnesium silicate minerals with CO2 to form stable, benign solid carbonate minerals for return to the environment. The process has been demonstrated in batch-type laboratory-scale tests over a wide range of temperatures and partial pressures of CO2 (PCO2). Research to date has advanced the understanding of the kinetics and important parameters of the reaction, but the development of a continuous reactor is necessary to prove the process on a larger scale. Preliminary engineering feasibility studies will be conducted to help define appropriate reactor systems for the carbonation step in the direct mineral carbonation approach. Several different reactor systems will be investigated, such as conventional continuous-flow stirred autoclaves and pipe-line reactors. However, the expected lower capital cost of pipe reactors makes that the favored concept for use in the mineral carbonation step in aqueous-based processes that operate at high temperatures and pressures.
