英文摘要 | The primary objectives of this project are to (1) demonstrate the performance and fabrication of a technically and economically viable pre-combustion-based CO{sub 2} capture system based on the high temperature stability and permeance of PBI membranes, (2) optimize a plan for integration of PBI capture system into an IGCC plant and (3) develop a commercialization plan that addresses technical issues and business issues to outline a clear path for technology transfer of the PBI membrane technology. This report describes research conducted from April 1, 2007 to March 30, 2012 and focused on achieving the above objectives. PBI-based hollow fibers have been fabricated at kilometer lengths and bundled as modules at a bench-scale level for the separation of CO{sub 2} from H{sub 2} at high temperatures and pressures. Long term stability of these fibers has been demonstrated with a relatively high H{sub 2}/CO{sub 2} selectivity (35 to 50) and H{sub 2} permeance (80 GPU) at temperatures exceeding 225Ă°C. Membrane performance simulations and systems analysis of an IGCC system incorporating a PBI hollow fiber membrane modules have demonstrated that the cost of electricity for CO{sub 2} capture (<10%) using such a high temperature separator. When the cost of transporting, storing, and monitoring the CO{sub 2} is accounted for, the increase in the COE is only 14.4%. |
