Intégration d'un procédé de récupération du CO2 par membrane, dans le schéma d'une centrale thermique IGCC en vue de son stockage

Abstract : Combustion power plants are an important localized source of COz, and are therefore appropriate for considering its recovery, for subsequent injection in oil wells or other possible modes of disposai. The present study is in the context of an futegrated Coal Gasification Combined Cycle power plant (IGCC), producing after conversion a pressurized hot mixture containing COz and Hz as major components. It appears appropriate to recover a part of CO2 from this mixture, before hydrogen is burnt in the combustion chamber of a gas turbine. Severa! potential COz recovery techniques can be considered : absorption, adsorption, membrane and cryogenie processes. Although these technologies are basically feasible from a technical viewpoint, their efficiency, reliability, long-term performance and economies are still uncertain. Among_ these technologies, membrane processes seem attractive, because they are continuous, and less sensitive to operating parameters than other techniques. An experimental study has been performed on inorganic membranes, in order to evaluate membrane performances, the aim being to design the separation unit. Based on experimental results, the power plant with conversion unit, membrane unit, and CO2 liquefaction system has been modelled in order to evaluate the overall energy penalty
