Bench-Scale Process for Low-Cost Carbon Dioxide (CO2) Capture Using a Phase-Changing Absorbent
Project No.: DE-FE0013687


GE global is constructing and operating a continuous, bench-scale CO2 capture system that employs a phase-changing silicone solvent . Experimental data obtained at the laboratory scale in a previous ARPA-E funded project, including mass transfer and kinetic information, is being used to determine process scalability and perform a techno-economic assessment of the commercial scale process. The manufacturability of the solvent is being examined to obtain the material needed for bench-scale testing. Data obtained from the bench-scale system will include mass transfer parameters, kinetic parameters, heat transfer parameters, solvent stability, effects of flue gas contaminants, and recommended operating conditions. Other data such as absorption/desorption isotherms and solvent regeneration energy will be determined in laboratory testing. The solvent manufacturing cost, the bench-scale engineering data, and the laboratory property data will be used to complete the techno-economic assessment and to develop a scale-up strategy for commercialization.
