CO2 capture in oil refineries-an evaluation of different heat integration possibilities for heat supply to the post-combustion process
Paper i proceeding, 2011

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.
