Product Description
This presentation discusses the development of baseline Direct Power Extraction (DPE) plant designs incorporating oxy-coal combustion, a magnetohydrodynamic (MHD) topping cycle, a steam bottoming cycle, and a carbon dioxide purification unit for carbon capture and storage (CCS). Two MHD configurations have been developed; one representing the current state-of-the-art in MHD channel design, and a more advanced design capable of higher power density. The MHD cycle incorporates potassium seeding for plasma generation and a potassium formate seed recovery process that also removes sulfur from the combustion products. The air separation unit for oxygen production, MHD system, and seed recovery systems are all thermally integrated with a Rankine bottoming cycle operating at advanced ultra-supercritical (AUSC) steam conditions. The modeled performance of the two DPE plant systems are compared to IGCC and oxy-coal AUSC reference plants with CCS.
