A Comparative of Life Cycle Assessment of Post-combustion, Pre-combustion and Oxy-fuel CO2 Capture

Energy and exergy analysis of chemical looping combustion technology and comparison with pre-combustion and oxy-fuel combustion technologies for CO2 capture

Carbon dioxide (CO2) emitted from conventional coal-based power plants is a growing concern for the environment. Chemical looping combustion (CLC), pre-combustion and oxy-fuel combustion are promising CO2 capture technologies which allow clean electricity generation from coal in an integrated gasification combined cycle (IGCC) power plant. This work compares the characteristics of the above thr...

Optimal conception of a post-combustion CO2 capture unit with assessment of solvent degradation

The combination of growing energy demand and environmental concerns has made the development of CO2 capture and storage technologies a necessity for the near-future energy mix. Post-combustion CO2 capture is one of the most mature technologies for reducing CO2 emissions in power plants. As a next step for the technology development, large-scale demonstration capture plants have to be implemente...

Oxy - fuel combustion of coal and biomass blends

The ignition temperature, burnout and NO emissions of blends of a semi-anthracite and a high-volatile bituminous coal with 10 and 20 wt.% of olive waste were studied under oxy-fuel combustion conditions in an entrained flow reactor (EFR). The results obtained under several oxy-fuel atmospheres (21%O2-79%CO2, 30%O2-70% CO2 and 35%O265%CO2) were compared with those attained in air. The results in...

Homogeneous oxidation of mercury during combustion: A comparison between combustion in air and oxy-combustion

Since oxy-combustion is a relatively new technology, many problems associated with the behavior of coal in this novel combustion process still need to be solved. In particular, there is a lack of knowledge regarding the behavior of toxic trace elements, and there is a need to determine whether trace element distribution among the by-products and emissions to the environment, is comparable with ...
