Performance of an Integrated Gasification Direct-Fired Supercritical CO2 Power Cycle

This presentation discusses development and performance results of a coal gasification system integrated with a direct-fired supercritical CO2 (sCO2) power cycle. In this plant, coal is first gasified and cleaned in order to avoid introducing sulfur and particulate matter into the sCO2 cycle, with the sCO2 cycle’s oxy-combustor burning the cleaned syngas with oxygen in a recycled sCO2 stream. The plant is inherently amenable to carbon capture and storage (CCS) processes, as it produces a high pressure exhaust stream that is largely comprised of CO2. The baseline direct sCO2 cycle performance is discussed and compared to IGCC and oxy-coal AUSC reference plants with CCS. The sensitivity of the sCO2 cycle’s performance to various operating parameters is also discussed, as well as the effect of various heat integration options on thermal efficiency, operability, and cost.
