Etude de la capture du CO2 par absorption physique dans les systèmes de production d'électricité basés sur la gazéification du charbon intégrée à un cycle combiné

摘要

The reduction of greenhouse gas emissions call for new strategies toward the use of fossil fuels. The study is aimed to assess the possibility of reducing CO2 emission from an Integrated Gasification Combined Cycle plant. A comparative study of the CO2 capture processes retained in literature (MEA-MDEA, AMP, N-Methyl-Pyrrolidone and methanol) led to the choice of the physical absorption by methanol. The simulation of the IGCC with CO2 capture was carried out with the Aspen Plus
