EGU GHG CONTROL OPTIONS - EARLY TRENDS AND RESULTS

摘要

Under the Environmental Protection Agency's (EPA's) latest regulatory action related to climate change, certain new and modified sources will be subject to stringent regulations focused on reducing emissions of greenhouse gases (GHG). The regulation requires each source to conduct an evaluation to determine the Best Available Control Technology (BACT) for GHGs. Currently, very few permits have been issued that address BACT for GHGs. PPRP and ERM present a technical evaluation focused on the potential results of a conceptual top-down BACT analysis conducted to identify possible control options for combustion turbines and coal-fired boilers, including efficiency related techniques as well as post combustion control equipment. While BACT determinations are unit-specific, this evaluation provides a generic analysis for large, utility-scale, electric generating units. A goal of the presentation is to provide a further understanding of the technologies available for review when a new or modified power plant conducts a GHG BACT assessment.
