This paper estimates the costs of CO2 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 €/ tCO2 avoided; depending on technology choice for heat supply and energy penalty for the CO2 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 CO2 emission changes outside the refinery are included or not.
