英文摘要	Because the fleet of coal-fired power plants is of such importance to the nation's energy production while also being the single largest emitter of COâ, the development of retrofit, post-combustion COâ capture technologies for existing and new, upcoming coal power plants will allow coal to remain a major component of the U.S. energy mix while mitigating global warming. Post-combustion carbon capture technologies are an attractive option for coal-fired power plants as they do not require modification of major power-plant infrastructures, such as fuel processing, boiler, and steam-turbine subsystems. In this project, the overall objective was to develop an advanced, hollow-fiber, polymeric membrane process that could be cost-effectively retrofitted into current pulverized coal-fired power plants to capture at least 90% of the COâ from plant flue gas with 95% captured COâ purity. The approach for this project tackled the technology development on three different fronts in parallel: membrane materials R&D, hollow-fiber membrane module development, and process development and engineering. The project team consisted of RTI (prime) and two industrial partners, Arkema, Inc. and Generon IGS, Inc. Two COâ-selective membrane polymer platforms were targeted for development in this project. For the near term, a next-generation, high-flux polycarbonate membrane platform was spun into hollow-fiber membranes that were fabricated into both lab-scale and larger prototype (~2,200 ftÂ˛) membrane modules. For the long term, a new fluoropolymer membrane platform based on poly(vinylidene fluoride) [PVDF] chemistry was developed using a copolymer approach as improved capture membrane materials with superior chemical resistance to flue-gas contaminants (moisture, SOâ, NO_x, etc.). Specific objectives were: - Development of new, highly chemically resistant, fluorinated polymers as membrane materials with minimum selectivity of 30 for COâ over Nâ and COâ permeance greater than 300 gas permeation units (GPU) targeted; - Development of next-generation polycarbonate hollow-fiber membranes and membrane modules with higher COâ permeance than current commercial polycarbonate membranes; - Development and fabrication of membrane hollow fibers and modules from candidate polymers; - Development of a COâ capture membrane process design and integration strategy suitable for end-of-pipe, retrofit installation; and - Techno-economic evaluation of the "best" integrated COâ capture membrane process design package In this report, the results of the project research and development efforts are discussed and include the post-combustion capture properties of the two membrane material platforms and the hollow-fiber membrane modules developed from them and the multi-stage process design and analysis developed for 90% COâ capture with 95% captured COâ purity.
