Dresser-Rand (D-R) will design, build, and test a pilot-scale supersonic carbon dioxide (CO2) compressor for new and existing coal-based electric generating plants for carbon capture and storage (CCS) applications. The commercial embodiment of a compression system for CCS would utilize a 10:1 pressure ratio low pressure (LP) compressor and a 10:1 pressure ratio high pressure (HP) compressor delivering the required overall 100:1 pressure ratio. This project will focus on testing the existing HP development compressor and the design, manufacture, and testing of a corresponding LP compressor. The LP compressor will have a single-stage 10:1 pressure ratio with a CO2 flow rate of 100 pounds per second (lbm/s) suitable for CCS applications in 125 MWe coal-fired power plants. Dresser-Rand will test the existing HP compressor; perform an initial techno-economic analysis; design, construct, and test the LP compressor; and perform a final detailed techno-economic analysis, including integration into a 550 MWe power plant. Testing will be conducted at the D-R plant in Olean, New York, on CO2 gas representative of a CO2 capture system in a CCS process. Upon completion of the tests, the LP and HP pilot compressors will be installed at a field site to validate their performance when integrated into a full system configuration.
Predecessor Project: FE0000493
Testing of both the HP and the LP compressors in parametric and steady-state operation will confirm that the operating characteristics and performance levels are on track to meet the U.S. Department of Energy’s CCS goals for development of a pathway to achieve a deployment of a commercial process by 2025 at a cost of $40/tonne of CO2 captured. The benefits of the proposed supersonic compressor include reduced capital cost, a smaller footprint, and reduced parasitic plant loss impact for carbon capture systems and the CCS process.
