Abstract

This review is devoted to assess and compare various processes aiming at recover CO<sub>2</sub> from power plants fed with natural gas (NGCC) and pulverized coal (PC). These processes are post combustion CO<sub>2</sub> capture using chemical solvents, natural gas reforming for pre-combustion capture and oxy-fuel combustion with cryogenic recovery of CO<sub>2</sub>. These processes were evaluated to give some clues for choosing the best option for each type of power plant.
The comparison of these various concepts suggests that, in the short and medium term, chemical absorption is the most interesting process for NGCC power plants. For CP power plants, oxy-combustion can be a very interesting option, as well as post-combustion capture by chemical solvents.
