| 초록 | It is now recognized that the anthropogenic emissions of greenhouse gases are involved in the global warming problem. The principal sources of CO2 releases from combustion of fossil fuels, which are used for power generation, transport, heating and many other purposes. Moreover, coal remains available for several hundred years. For these reasons, it is important that there should be technology options that would allow continued use of fossil fuels without substantial emissions of CO2. In pre-combustion CO2 capture, the CO2 is recovered from some process stream before the fuel is burned. To the extent that the concentration and pressure of the CO2 containing stream can be increased, then the size and cost of the capture facilities can be reduced. This has led to efforts to develop combustion technologies that inherently produce concentrated CO2 streams or CO2 containing streams at high pressure, for which there are existing capture processes. Membrane systems are seen as an attractive technology for pre-combustion CO2 capture in gas fired power stations because they combine, all in one reactor, the efficient conversion of coal gasification gas into H2 for power production with capture of the remaining CO2. The membrane reactor is integrated in a conventional power cycle, where the hydrogen is used for power generation, while the remaining gas stream contains mainly CO2 and some non-recovered hydrogen and steam at relatively high pressure. Subsequent condensation of the steam leaves concentrated CO2 at high pressure, reducing the compression energy for transport and storage. This presentation will describenovel approaches, membrane technology , doing projectfor the separation of carbon dioxide (CO2) at the pre-combustion stage of gasification-based power generation point sources. |
