CO2 capture processes in power plants - Le captage du CO2 dans les centrales thermiques

TL;DR

This review compares CO2 capture methods in power plants, evaluating post-combustion, pre-combustion, and oxy-fuel processes to identify the most suitable options for natural gas and coal plants.

Contribution

It provides a comparative analysis of CO2 capture technologies, guiding optimal process selection for different types of power plants.

Findings

Chemical absorption is most suitable for NGCC plants in the short and medium term.

Oxy-fuel combustion and chemical solvent capture are promising for coal power plants.

The review offers insights into the advantages of each CO2 capture process.

Abstract

This review is devoted to assess and compare various processes aiming at recover CO2 from power plants fed with natural gas (NGCC) and pulverized coal (PC). These processes are post combustion CO2 capture using chemical solvents, natural gas reforming for pre-combustion capture and oxy-fuel combustion with cryogenic recovery of CO2. 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.
