A quantitative comparison of gas turbine cycles with CO2 capture

摘要: Abstract Nine different concepts for natural gas fired power plants with CO2 capture have been investigated, and a comparison is made based on net plant efficiency emission of CO2. The cycles are one post-combustion, six oxy-fuel two pre-combustion concepts. A 400 MW combined cycle applied as reference case. common basis the all defined employed in heat- mass-balance simulations various As turbine cooling impacts at high inlet temperatures, simplified model has simulations. It found that concepts, which novel technology (the hydrogen membrane separation reformer—-MSR-H2, advanzed zero plant—AZEP, solid oxide fuel cell turbine— SOFC + GT chemical looping combustion—CLC concepts) employed, exhibit best performance respect to both most cases also (capture rates close 100%). Post-combustion auto-thermal reforming, more mature technology, show lower rate typically 90%. concept exhibits even better than standard CC plant, however, any realization SOFC-GT very distant future perspective. In order conduct complete assessment these diverse other criteria such e.g. level costs should be considered. This not, included present work.
