This paper estimates the costs of CO 2 post-combustion capture for two refineries by comparing different alternatives for supplying the heat needed for the regeneration of the absorbent. The cost of capture ranges from 30 to 472 €/ tCO 2 avoided, depending on technology choice for heat supply and energy penalty for the CO 2 separation. In this study, it is concluded that process integration leads to a reduction in avoidance costs. However, the avoidance cost depends greatly on which system perspective is considered, i.e. whether CO 2 emission changes outside the refinery are included or not.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
