Abstract
The University of Illinois Urbana-Champaign's Prairie Research Institute and Covanta Corporation will design, build, and operate a pilot-scale carbon dioxide (CO2) capture system at a Covanta waste-to-energy (WTE) facility that combusts municipal solid waste (MSW) to generate steam for the City of Indianapolis. The University of Illinois' transformational biphasic solvent-based CO2 absorption process (BiCAP) technology was previously tested at a 0.7 tonne CO2/day scale on coal-derived flue gas at the Abbott Power Plant located on the University of Illinois Urbana-Champaign campus. In this project, the technology will be scaled up to capture 2.5 tonnes CO2/day from combustion flue gas at the WTE facility, and the pilot unit will be designed to maintain a capture efficiency of ≥ 95% and produce CO2 with ≥ 95% purity. The project will assess the economic and environmental performance of the technology and the potential net-negative CO2 emissions associated with energy production from burning MSW when carbon capture is incorporated. The impact of the project on environmental justice and the regional economy will be analyzed, and a workforce readiness plan will be developed.
